Metadata Sharing Strategy
Hi,
In the standard SOA install you have a SOA infra metadata repository.
When AIA is installed AIAMetadata is then added to this repository.
AIAMetadata contains the abstract WSDL’s, xsd’s etc. for all the enterprise level artefacts.
We have Development, Test and Production SOA Servers which each have their own metadata. We have a patching system which deploys metadata to each sever.
It has crossed my mind that we could have a single metadata store and connect all three SOA Servers to that one. There are already strict rules for adding files to metadata so this should not be a problem. There is also the need for other systems (ADF servers, OSB, etc) to access the abstract WSDL’s. This would avoid all the management issues involved in creating metadata in Dev and needing it to be moved from system to system.
What are the best methods to share enterprise metadata across the environments?
Thanks
Robert
Robert,
while your thoughts make sense conceptually, there are technical constraints that would not allow one central MDS for all your environments. If you take a closer look at your MDS, you will not only find the AIA meta data you described, but also environment specific data such as the deployed composites for a SOA infrastructure that is connected to that MDS.
So the best parctise at this point is to maintain the source of truth of your shared AIA meta data on the file system, typically managed through a source control system. You use a file system level tool to keep the meta data in your AIA Homes in synch as required and then use the usual AIA deployment tools to get this moved to each MDS. I assume this is what you already do anyway.

Does anyone have any suggestions for a family needing to share and play iTunes on or via multiple devices?
Here's the scenario.
i) 3 users in a house.
ii) Installed in the house, 2 x Apple TV and a MacMini.
iii) 2 Users have MacBooks, one of these users has an iPhone, the other an iTouch
iiii) 3rd user has iTouch.
Each of the users has an iTunes library and whatever the strategy, they would like to keep the libraries separate.
The ideal solution would be that the MacMini is a music server but, only if there's no need to switch users as the only access to the MacMini is via the network.
Is there a way to keep each users's music separate on a single user account? (other than dragging music into libraries!)
The current problem is extended because there are 7 AirPort Express units driving speakers in different rooms. When another Mac or iTouch/Phone tries to use a remote library, if the remote Mac is set to use multiple speakers, music plays in rooms not required but there's no way for the remote user to control the multiple speaker settings. Is there, maybe, a script that triggers when a remote user logs on and automatically re-sets multiple speakers to computer only?
Is there a way, if the iTunes account users agree to share, that an iTunes user can enter more than one account name to overcome the sharing problem of 5 registered devices?
Has anyone written a multiple Mac, iTouch, iPhone and AppleTV iTunes strategy?
Appreciate any suggestions.
Regards, NormI'm still searching for an iTunes / Apple TV Home Sharing solution but wonder if anyone thinks this idea might work ...
Here's the hardware situation (ASA = Apple Store Account):
House
Apple TV Lounge ASA User 2
Apple TV Master Bedroom ASA User 2
Apple TV Pool Room
MacMini ASA (User4 ?)
User 2
MacBook Pro ASA User 2
Apple iPhone ASA User 2
User 1
MacBook Air ASA User 1
iTouch (Music from iMac in Office) ASA User 1
(Office iMac) ASA User 1
User 3
iTouch ASA User 2
* ASA = Apple Store Account
Create a new ASA in the name of thehouse. Set up the MacMini with 4 users, User1, User2, User3 and User4 (thehouse) each using their own ASA. Enable fast user switching and have automatic start-up on all 4 accounts (if possible?). Set-up Home Sharing on the MacMini using User4 ASA (thehouse) Have each user's iTunes music synced from their personal device/s to the MacMini. This should mean that User1, User2, and User3 will each have an iTunes replica of their master much library. User 4, the new thehouse account, will also be used on the Apple TVs in the living room, Master Bedroom and (soon to be installed) Pool Room. Hopefully, the MacMini will, via Home Sharing, make all three iTunes libraries available to all the Apple TVs.
Anyone think this might work? -
Hi all,
with the command mdls we can obain information on the medadata of a file.
In particular I need to use the information provided by the field: kMDItemLastUsedDate, that
is updated with the last moment a file was read.
I noticed that the field is normally updated if I read a file locally.
Some problems arise when I read the files on a shared volume even if I access the volume with the local user account.
In this situation the field isn't updated and it's like none has read the file.
Is there any option in order to make the field always updated.
Thanks.Whenever you paste an icon onto a disk or folder, the Finder creates a .VolumeIcon.icns or Icon? file, which contains your custom icon. The inability to see the custom icon may simply be a permissions issue. Check to see that the icons files have at least read-only permissions for the users who are connecting.

Creating less expensive small xSAN for 2 editors - suggestions?
I've been setting up a second editing bay for our company which is supposed to have identical capabilities to my own. It's a Quad with Kona LHe, just like I'm using. We mostly edit TV comercials in DV50, uncompressed 10bit SD and DVCProHD 720P so our bandwidth requirements usually out spec editing over ethernet.
Since both editors need to have equal capability, I have chosen to create a small xSAN to allow both editors to access the same media drives simultaneously. With a SAN, large server volumes (located on a fibre channel network) show up on the editor computers just as a simple local hard drive would at very fast speed. You can point FCP scratches to the same places on each machine, then use any machine to edit any project instantly. My budget is large by my standards, but not very large on the scale of typical xSAN implementations so I've been collecting "deals" on the gear I need before I put it all together.
Since I'm on a budget, it has been fun finding much of the gear on ebay, etc. FYI, here is a quick list of the stuff I've acquired:
xServe RAID 5.6TB refurbished from Techrestore.com: $5900
xServe 2Ghz Metadata controller w/ Tiger Server 1.5GB ECC RAM, PCIX fibre card new, but last year's model from Smalldog: $2600
Brocade Silkworm 3200 8 channel 2Gb entry fibre switch new on ebay: $950
2 PCI Express fibre cards new for 2 editor G5 quads: $1100
3 xSAN licenses new on eBay: $1300
Mini GB ethernet network stuff and switch (for metadata only - separate from our LAN network): $150
Misc. fibre cables and tranceivers: $700
One of my editing G5's will act as the fallback Metadata controller in case the xServe goes down at any time.
I also am planning on at least 8 hours of time from a local xSAN authorized tech to help me set everything up and teach me what I need to maintain the system. This should be about $700 or so.
I have found several articles posted at xsanity.com very helpful in planning this.
If any of you have any experience with xSAN, you might agree this is a very low cost of entry into this very exciting new workflow. $13.5K for a fully functioning xSAN of this size is not bad at all. Many would spend that on the xServe RAID alone, sans SAN;-) And I can expand very easily since my switch will still have 3 unused ports. Note: the 5.6TB xServe RAID will only be about 4TB after accounting for the RAID 5 and dedicated (and mirrored) metadata volumes. Only 4TB. Pity!
Now that I have the main hardware components ready, it's time to install and setup the system. I'll be posting my progess in the next few weeks as this happens, but first would like to hear any impressions on this. Suggestions or warnings are appreciated by those with experience with xSAN. The xSAN forum here at Apple is used mostly by IT professionals and I'm mostly interested in hearing comments from editors and those that use the system in small settings like my own.
One question for the Gurus: I don't believe FCP projects can be opened and used by two people at the same time, but if there is a way to do this without corrupting the project file, I would love to know.
I'm also seeking to hire an assistant to occupy the new editing bay. Broad multimedia skills are needed, but I can train to a degree. We're an advertising agency just north of Salt Lake City, Utah. Please let me know if any of you are interested.Thanks for the suggestions. Brian, I'll be sure to get you some points once I close the topic.
I didn't realize the Project files are best copied to the hard drive. Is this for a permissions related reason or just to avoid short spikes in bandwidth during saves?
I agree that Metadata is best on a dedicated controller with full scale xSANs, however with just 2 systems editing mostly DVCPro50 resolution projects I can't imagine burning up more than 100MB/sec at any given time. OK, maybe, but this is unlikely for next year or so. I've read that a single controller can achieve 80MB/sec easily, so 2 should be around 150MB/sec under heavy load. I'll have the metadata mirrored to 2 drives on one side of the XSR and the remaining 5 drives on that controller in a RAID 5. The other side of the XSR will be a full 7 drive RAID 5. These 2 data LUNs will be striped together in xSAN to achieve a full bandwidth of about 150MB/sec. I was told that the XSR controller can handle multiple RAID's at the same time so I can send metadata to one mirror array and designate the other as a RAID 5 LUN. Considering the small size of the data going to the metadata volumes and the relative simplicity of RAID 1 mirroring, I believe the controller shouldn't be adversly affected by this. Is this incorrect in your experience?
I do plan on turning off the cache of the XSR since the system will be used for editing, yet it would be nice to have cache for the metadata so that's a point to consider.
THe metadata should be segregated on its own XSR controller.
Are you saying that the metadata sharing the same controller as the video data is going to slow the whole system down even though the metadata is located on separate, dedicated drives in that controller? I thought metadata was tiny and required very little bandwidth on the bus of a controller. If this is the case, the only bottleneck would be the RAID chip in the XSR. Again, these metadata files are very small and RAID 1 is very simple, so I don't see how it could slow things down enough to justify another $4K for a new XSR. If you still disagree, please let me know.
As per your suggestion, and considering your stellar reputation in this forum, I'm shopping right now for a mostly empty xServe RAID to use this for just the Metadata volumes mirrored. It just seems like a huge waste to get an XSR just to use 2 drive bays mirrored. The plus side of this is I could begin filling the other controller in the future as my storage needs expand.
It would be really cool to use the 2 drive bays in the Xserve Metadata controller for the metadata volumes, but I can see how that would cause problems if the xServe goes down, making the metadata invisible to the fallback MDC. 100% uptime isn't that big of a deal for me, however. As long as the XSAN comes back online safely after the xServe reboots without trouble, I'm OK with such a setup. Have you ever seen this done? It seems a bit of a hack to use anything but fibre channel data. I'd hate to introduce too much complexity just to save some bucks, but it is an intriguing idea and would cost a fraction of a new XSR. It would be fast since the writing the metadata would be local with very little latency.
For this reason, I'm also very interested to find any other simple and less expensive Fibre based storage solutions that could host my metadata as an alternative to full blown XSR for this. There are all kinds of fibre drives out there, but I don't want to waste a valuable fibre switch port just for one drive. All I need is 2 hardware mirrored bays accessible over fibre, preferably sharing the same channel on my switch. Does anyone know where I might find something like this? -
Hello everyone
I'm hoping to receive some advice on the best way to store a large collection of music, pictures and video, whilst keeping my computer as empty as possible to maximise it's processing power for professional video editing in the future. The computer is for both personal and business use, and I share it with my partner who is a music fiend, but not computer savvy.
I have recently purchased a new 27" iMac with the standard specs (3.1GHz Quad-Core Intel Core i5, 4GB memory, 1TB hard drive). It is currently running Snow Leopard (v. 10.6.6), and I plan to update to Lion when I purchase a new broadband account.
I also have:
One external 1TB Western Digital drive, currently at 85% capacity, with music, videos and pictures
One external 1TB Western Digital drive, currently empty
A new 2TB time capsule which is not yet set up
Apple TV, not yet set up
A mobile USB modem and basic account, soon to be replaced by a fairly high speed broadband modem with a fairly large download cap
So far, I have:
created three user profiles - one administrator, and two users
Set up iTunes so each user shares a single library and itunes media folder
We would like to also digitise a large collection of CDs and records.
I was thinking about using the time capsule not only for storage/back up, but also to create a wireless network, allowing it to be stored with my printer and the hard drives can be stored in different room to the computer, away from sight. The computer is so very gorgeous on it's own after all.... I've been advised also to use it as a wireless router when we purchase our broadband account, so I'm assuming the modem should also be connected to the time capsule in the other room.
Rather than droning on about what I think I should do, I wondered if one of you experts could advise me on the best way to set everything up? I'm not sure that it's the best idea to set it up so the computer is always having to find files wirelessly from the time capsule and connected drives... Wouldn't that be slow?
The advice I've read in the various forums has been rather confusing, so your advice would be really appreciated!!
Cheers
FionaHi Fiona,
Like your question, I'm in same boat and new to iMAC all together and want to setup backup and sharing strategy via best practice right up front. Did you get any response or any good best practice you ran across in your research you an share with me? Thanks. -
Smartview Refresh Changes Dimensions To Old Version
I am having an issue refreshing a smartview file that our department shares on a public network drive. When our users save the file to their own computer, open in smartview and refresh, the member options/dimensions change to an older saved version. We have all become used to this situation when only one or two dimensions would change but now as we are changing from forecast to plan and 2013 to 2014, etc. it is creating a bigger issue.
Are there some settings or bugs that anyone knows about so that no matter what members are selected in the POV, when the file opens they stay and dont revert back?Log into HSS (Hyperion Shared Services) console (http://server:port/interop/index.jsp)
Expand the Application group->Foundation->Deployment Metadata->Shared Services Registry->Essbase-> APS LWA
Check the host/server name and port in the properties files present beneath them if they are pointing to the right server and port.

Hyperion Provider Services Connectivity to the Essbase Server
Hi All,
I have seen a new issue in Epm 11.1.2 Issue is
I have installed my provider services services are now up and running in port 13080
Now when Iam trying to connect thru smartview Iam using following URL
http://Servername:13080/aps/SmartView
When Iam going thru the new connection creation process
Step 1 when I give the URL and click on the next its shows up next page.
In this page basically I have to select the server and the application.
But here in my case server and application doesnt show up its BLANK.
I have checked from my browser provider services shows up perfectly
Have anyone faced this issue let me know your ideas
Thanks,
KRK

Below are the steps to resolve the issue.
1. stop APS

3. Expand Application group->Foundation->Deployment Metadata->Shared Services Registry->Essbase-> And locate APS LWA
4. Right click on datasources.xml file and “Export for Edit”
5. Save the datasources.xml file and not open it.
6. Open with notepad and make changes so that essbase server name is listed like below:

In looking at this I could not find the datasources.xml file reference following your outline. -
For the background processes we make use of JMX Beans.
We develop them with JDeveloper 10g (10.1.3) and deploy to OC4J.
We have a background proces for the processing of messages (xml-files from a queue) into the database (using ADF BC).
Most of the time this works fine, but sometimes it seems that the process is hanging (?), there are no error messages (not in logfile of the application and not in the directories of the Oracle Application Server). We had to restart the process and then the same message has to be processed well.
In the Java code we put a lot of debug-messages.
When it goes wrong, the last debug message is just before the database commit (getTransaction().commit()).
In the database there are no locks, waiting processes, or something like that, at the moment.
Any tips how I can figure out what the problem can be?Since the problem is periodic, I guess this is happening because of some weekly loads. There might be some weekly loads running on every Saturday, which is consuming most of the resources and hence creating problems for your PC.
To process the Idocs manually, you should go in SM58, select the Idocs, and press F6.
To get rid of this, you should have a proper load sharing strategy.
To get a mai/notification, this is possible. You need to include an ABAP program in your PC and configure your mail box. As soon as some loads fails, it kicks out a mail. I used to get a mail in such cases.
Thanks...

SuperDrive Media Disc(s) .. Assist ...
07.11.2005
Dear Apple Mac Mini User forum participants
b Macmini SuperDrive : Matsushita DVD-R UJ-845C
How do we confirm the correct read/writable disc(s) media for our Mac mini ?
We have searched widely .. specifically .. and generally .. online.
And we come away with no new definitive knowledge. Others
have trialled and erred .. and learned .. and reported. But still
we are ill-informed about which particular media we should
be restricting ourselves to use in our Mac mini.
Are you able to assist by sharing your garnered information(s)
about the correct media(s) for the Mac Mini Superdrive.
We seek your illumination by kind response, if you will.
Point us to the worthy online repositories or share your personally
accrued gems of optical SuperDrive media disc management.
And finally, for now, we would like to hear your formula for establishing
the minimum specification to share your media disc(s) among your Mac
computers in use and even with an XP machine, from time to time.
Establishing the upper performances and the lower compatibilities would
provide a practicable strategy to managing machine restricted and machine
to machine informations sharing by optical drive media disc(s).
Positively thanked will you be.
very much obliged,
Stuart .09.12.2005
Dear Apple Mac mini user discussions participants
Thank you to everyone who has constructively added to
the body of useful knowledge now available in this
humble thread. Your contributions are genuinely prized.
Gems.
We have read and re-read your entries, acting where
able, to discover more about the true capabilities of
the Mac mini SuperDrive mentioned. Along the way, we
have discovered a few many other related and relevant
aspects to the personal industry of media disc burning.
Here is the Apple Mac mini ..
About This Mac ..
More Info ..
Disc Burning ..
MATSHITA DVD-R UJ-845C:
Firmware Revision: DPP9
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No
One of the informations we seek is the speeds capacities
of the SuperDrive mentioned. More frequently now .. in
the stores .. you find speed rated disc media for
burning. What are the rated speeds of the Mac mini
SuperDrive and media ?
What does CD-TAO mean ? TAO : TrackAtOnce
What does CD-SAO mean ? SAO : SessionAtOnce
What does DVD-DAO mean ? DAO : DiscAtOnce
What does .. Media: No .. mean ?
From here we begin to discover compatible media ..
the original mission.
Online .. here and elsewhere .. we are educated by the
many who have trialed and erred before us. Most demanded
manufacturer of disc burning media is 'Taiyo Yuden(s)'.
Made in Japan. Taiyo Yuden Company Limited is mentioned
by www.cdfeaks.com WIKI as the most preferred media too.
Most recommended brand name of disc burning media is
Verbatim.
We searched for Taiyo Yuden(s) media in our geographical
locale. Rare as hens teeth. Sold out before arrival.
Premium price no deterrent to those in the business of
quality disc burning. We settled for a couple of
Verbatim DVD+RW media discs. Made in Taiwan. Every disc
we could locate in retail was either made in Taiwan or
made in Singapore.
We began our media disc burning adventure by applying
the native OS X Tiger 10.4.2 disc burning applications.
Finder and Disk Utility. We bothered not with itunes,
iphoto, since our mission is data. Problems emerged
early. From the log file automatically kept by Disk
Utility (top right hand corner of the DU window) you are
able to read for yourselves the two error messages
reported as operations failed. Error messages ...
Finishing burn
Verifying burn...

This disc did not verify correctly and is unreliable.
Because the disc is unreliable, discard it and try again
using a new, blank disc. (Error code: 0x80020063)
Success message - without verification ...
Burn completed successfully
Image “backup xxxxxxxxxxxxxx xx.xx.xxx.dmg” burned
successfully.
Operations failure .. we quickly discovered .. does not
mean media disc burn total failure.
All media disc burn operations were 'successful'. And,
as soon as we unticked Verify data at end of disc burn
(DU), we were regularly greeted with successful media
disc burn dialogue affirmation. Encouraging .. and
further confirmed as we examined the data burned and
satisfied ourselves of the totality of the writing
event. Otherwise .. DU had zero challenges media disc
burning and reading burned media and copying data files
back onto the originating apple mac mini hard disk
drive. Remember that DU is limited to media disc burning
in apple format only and multi-sessioning where on
screen you will be greeted with individual icons
representing each session burned on the same media disc
burned.
However, things went south far to soon and without very
apparent reason. The DVD+RW was suddenly and perpetually
rejected by the SuperDrive. No doubt .. the more
informed among you are smiling and nodding knowingly ..
at our novice and amateur opening efforts. Useless disc.
You may be able to pinpoint the moment of coaster
creation from the supplied error messages logged.
We imagine that the lack of verification availability ..
always displayed with an unsuccessful burn message,
every time .. points directly to media disc quality.
Unusable disc an eventual certainty. Perhaps.
Every disc burned delivered an unsuccessful burn message
whenever Verify data burned was ticked. Finder media
disc burning does not provide apparent opportunity to
switch off verification. Read-on .. if you are
interested to discover our further media disc burning
experiences and experimentations.
We re-examined the apple computer help system from DU
and learned that DVD+RW is the favoured alternate re-
writeable format disc for DVD re-writing intended to
replace the capabilities of DVD-RW and DVD-RAM and
provide higher compatibility with set-top players ..
though some DVD drives or applications may not support
recording to this disc format. At the store .. we re-
read the retail store chart by Verbatim on DVD options
and learned of media designation purpose distinctions.
Still .. we appear to have chosen within the SuperDrive
capabilities. Another disc we should like to sample is
the DVD-RAM disc .. which is not specifically mentioned
as compatible media .. are you able to clarify whether
Mac mini users with the mentioned SuperDrive
MATSHITA DVD-R UJ-845C are able to use this designation
? And the reason for the question is that we have
discovered a DVD-RAM disc available from a Japanese
manufacturer. Premium price at the retailer .. assuming
premium quality too. Appears, however that we are unable
to use DVD-RAM media burn disc(s).
After media disc burning the DVD+RW disc we then fed the
written disc (and at that time, readable - by the
originating Mac mini machine) to the iMac DV SE
(graphite) running OS X 10.4.3 Tiger to confirm
compatibility. Nightmare on Apple street. Barely able to
read the media disc burned .. we eventually had to force
the iMac cough the DVD+RW disc back out by manually
restarting the iMac machine (side button) and holding
the mouse button down on start-up. Disc retrieved ..
safely. First time ever in five years of ownership ..
since new. Bummer. To eliminate speculation of poor iMac
DV SE drive performance we set about throwing other CD
and DVD discs at the machine. Perfect. From the iMac ATA
Device Tree - ATA Bus ... (no media disc burning capability)
MATSHITADVD-ROM SR-8184:
Model: MATSHITADVD-ROM SR-8184
Revision: AA32
Serial Number:
Detachable Drive: No
Protocol: ATAPI
Unit Number: 1
Socket Type: Internal
Disk Utility and Finder are limited media disc burning
applications. DU creates multi-session disc by burning
separate instances that manifest as separate disc icons
on the desktop. Operationally limiting and eventually
problematical. iMac DV SE showed only the first media
disc burn of a multi-session disc burned. DU is limited
to media disc burning in Mac OS format only too.
We returned the DVD+RW discs to the retailer .. one
opened and used and fully rejected and the other
unopened. Instead we chose to step down to Verbatim
CD-RW discs .. made in Taiwan. We continue with our
experimentations. Finder help reveals more about disc
burning and under; "I got an 'unknown error' message
while burning a CD or DVD disc" we find two links ..
Apple Service & Support article: Problems burning discs
[http://www.info.apple.com/kbnum/n25480] reads ...
Mac OS X: "Unknown Error -2147352480" when burning CD-R,
CD-RW, or DVD-R media Learn how to troubleshoot burn
underrun protection issues ("Unknown Error -2147352480"
alert) when burning a disc. This document applies to Mac
OS X 10.2 or later.
Try these tips:
* Specify a burn speed that is less than the maximum
speed rating for the optical drive.
* Quit open applications you are not using. Open
applications are marked with a triangle in the Dock.
* Once a burn session has started, do not move, bump,
or vibrate the computer.
* Do not put labels on blank discs before burning them.
* Use blank discs that are rated for the burn speeds of
your drive, or consider using a different brand of media.
* See "Macintosh: Factors That Affect Writing to or
Reading From Optical Media".
Your computer may also benefit from installing additional
memory (RAM) or a higher-bandwidth system interface for a
burning device (such as SCSI).
You might also consider having the optical media device
tested by an Apple Authorized Service Provider.
Additional information
The Console utility or log may report:
"-2147352480 = 0x80020060 = kDRBurnUnderrunErr = Device
drained buffer without burn underrun protection"
Low disk space or RAM availability issues can lead to this.
These are some clues that this might be the case:<
* The issue more often occurs during the burn process.
* The failed burn more often leaves data partially
written to the disc, and he disc can't be reused.
Physical source of these issues can lead to burn failures
and can sometimes be identified when:
* The issue more often occurs at the start of the burn
process.
* The failed burn session more often leaves the media
untouched and ready to be burned. (It is still blank.)
* The burn starts, but an external incident interrupts
the session.

Factors that affect writing to or reading from optical media
This document discusses things can affect your computer's
ability to write CD and DVD discs, and what can potentially
affect their being read by other computers and consumer
electronics equipment.
Several things can affect the mastering of recordable media
and the ability to read them by other devices. These factors
equally apply to CD-R, CD-RW, DVD-R, and DVD-RW media.
To consistently achieve successful burns, be aware of these
factors
The source for the media
Third-party discs that conform to the specifications of the
drive should operate as expected. However, since Apple has
not physically tested these discs, you should contact the
manufacturer if full compatibility cannot be achieved.
Apple-brand discs are tested and qualified for use with
Apple-installed optical drives and are fully compatible.
The optical drive used to master the media
Earlier drives may not work with some later, high speed
media. Use discs recommended by your drive's manufacturer.
Make sure you have installed any firmware updates available
for the drive. Some updates may address media compatibility
issues, or update the function of the drive in other ways.
The software used to master the media
Make sure the application software you use to master the
discs is up to date. Make sure the options you choose in
the application, such as the burn speed, work with the
drive and the media you are using. Varying the burn speed
may affect the compatibility of the media in the playback
device. This may make a difference in the accuracy of the
mastering of an audio CD or DVD. Burning applications often
perform a verification after the burning process is complete.
This ensures that the final disc is ready for playback.
If the verification fails, try choosing a slower burn speed.
The connection method for your optical drive
If your burner is connected via USB, you may not be able to
burn at the highest speed the drive is capable of using.
Trying to burn at too high of a speed may lead to a failed
burn because there is not enough bandwidth on the bus.
If you have a SCSI burner, make sure the SCSI cabling is
configured correctly, and that the SCSI chain is properly
terminated. Issues may result from improper termination.
Also, make sure you use properly-shielded cables to connect
the burner to the computer.
To successfully use your burned media, be aware of these factors
The source of the media
In general, if you are able to successfully burn discs in a
drive, that drive should be able to read the same discs without
an issue.
Note: Apple optical drives work with standard 650 MB-capacity
discs, but not all drives work with 700 MB-capacity (80 or 90
minute) discs.
The optical drive used to read the media
Earlier optical drives may have issues reading modern media.
Early DVD-ROM drives, for example, may not read burned DVD-R
or DVD-RW discs. Some may read DVD-R, but not DVD-RW. This is
true for consumer audio CD players, car audio players, and
DVD-Video players, too. Depending on when the drive was
manufactured, it may or may not be compatible with certain
burned media. Check the documentation that came with the player,
or check with the manufacturer for more information. A firmware
update may be available that improves compatibility. Even if it
is considered "compatible" with certain media, you may encounter
issues with some brands of media, or issues with media burned at
certain speeds.
The software used to read the media
You may find that software designed to copy data to discs cannot
successfully copy video or audio to discs. Make sure you are
using a current version of the application, and that the software
can copy the kind of data you are working with.
For best success in reading media, use the latest version of
the Mac OS. Also, make sure that you burn the disc in a format
that can be used by the operating system that will read the disc.
For example, a CD burned in Mac OS Extended (HFS Plus) format
may not work with a Microsoft Windows-based computer.
If a disc's format is not normally recognized by the computer's
operating system, you may need to install software that allows
the computer to recognize it.

... Moving along ..
Finder help also explains about burning blank CD or DVD
disc(s) and states that it will create burned disc(s)in
'hybrid' format that can be read by most computers,
including Windows computers. The (burned) disc contains
these filesystem: HFS+, ISO-9660 with Rock Ridge, and
Joliet with Rock Ridge. However .. "The names of files,
folders, and the disc can't be changed after the CD is
burned." So, a CD-R or DVD-R would seem the appropriate
media disc(s) to use as they cannot be (erased and) re-
written .. on any machine. [ but they can be written
until full with other softwares and on other operating
systems .. e.g. XP ]
We used CD-RW to experiment with this capability .. by
media disc burning data files to find out what we could
do after the first Finder burn. Initially recognized as
a CDR media disc. As you, dear reader, are by now, well
aware, media burn automatic verification failed.
Automatic ejection occurred after the burn and at the
(usual) verification failure message from Finder.
Re-insertion (after a delayed period) showed the CD-RW
disc to be CD-RW Untitled CD .. even though we had
titled the disc at dialogue box burn time. One folder
and zero nested folder or data files content were shown
as recorded in the Finder window. We know something is
on the disc because the usage amount is shown as 353.6MB
on the desktop icon. Second attempt to burn gave
message: Insert a blank disc to begin. So CD-R is better
value (read: cheaper) media than CD-RW for Finder burns.
You can use use DU to erase the CD-RW. DU agrees with
the media burned disc volume usage.
Finder is doubly confusing because of two apparently
colliding help entry explanations.
Under: Disc burning options are dimmed or unavailable ..
is the explanation: If the entry contains "-R", your
computer can write to a CD-R or DVD-R disc only once. If
the entry contains "-RW", your computer can erase a CD-R
or DV-R disc and write to it again.
However ..
Under : I can't burn files on my recordable CD or DVD
disc .. is the explanation: If the entry contains "-R",
your computer can write to a CD-R or DVD-R disc only
once. If the entry contains "-RW", your computer can
erase a CD-RW or DVD-RW disc and write to it again.
Personal experience proves the latter explanation to be
the more correct one. We are unable to erase a CD-R or
DVD-R disc on either Mac or XP machines. Whew.
Are we missing something here ?
Or is that the correct facts of the designations ?
Finder also provides a run-down of Types of recordable
CD and DVD media.
Types of recordable CD and DVD media
If your computer has an internal or external recordable
optical drive supported by Apple, you can "burn" or
record your favorite music, applications, documents,
digital photos and video, and other digital files to
recordable CD and DVD discs. You can create your own
music CDs and play them on a standard audio player, or
create DVDs with movies and slideshows and play them on
a DVD player.
There are several types of recordable CD and DVD media:
• DVD-R discs hold about 4.7 GB of information.
You can burn files on a DVD-R disc using the Apple
SuperDrive. DVD-R discs are not reusable; you can burn
files on them only once.
• DVD+R is an alternate DVD Recordable write-once
format. Some DVD drives or applications may not support
recording to this disc format.
• DVD-RW discs hold about 4.7 GB of information on
each side. If you have an Apple SuperDrive, you can read
information on these discs, but you can't burn files on
them using Mac OS X. DVD-RW discs are reusable: you can
burn files on them, erase them, and then burn again (if
you have an application that is compatible).
• DVD+RW is an alternate DVD ReWritable format
intended to replace the capabilities of DVD-RW and DVD-
RAM and provide higher compatibility with set-top
players. Some DVD drives or applications may not support
recording to this disc format.
• CD-RW discs come in normal and high-speed
formats. You can burn files on CD-RW discs using the
Combo drive (or another supported CD burner). CD-RW
discs are reusable: you can burn files on them, erase
them, and then burn again.
• CD-R discs come in two types. One holds 74
minutes of audio, or about 650 MB of information. The
other holds 80 minutes of audio, or about 700 MB of
information. You can burn CD-R discs using the Combo
drive (or another supported CD burner).
For recording audio CDs, it is best to use CD-R discs
because most standard audio CD players cannot read CD-RW
discs. For longer-term storage and reliability, use CD-R
discs.
You can't burn anything on a CD-ROM or DVD-ROM disc.
Enter Microsoft Windows XP Professional
We are .. for once .. fortunate enough to have Microsoft
Windows XP machine available to us with media disc
burning hardware installed. Just like the Mac mini .. we
do not have any other software installed for media disc
operations, only from the native XP OS supplied tools.
However .. we quickly discover that the XP machine has
an edge .. licensed Roxio software integrated into the
XP OS. And it works well. We discover that the Apple OS
X media disc burning software Disk Utility .. chooses
only to format in Apple OS. Meaning .. DU media disc
burned with Mac mini are only able to be read by Apple
OS machines. Confirmed by attempting to have the XP
machine(s) read the disc burned. Unable. But .. media
discs burned by XP machines are able to be read by the
Apple machines. Because XP machines native OS media
disc burning format appears to be an industry standard
OS independent. Couldn't tell from the available
information from the XP OS but suspect it is an ISO 9660
format variation. To be exactly confirmed .. and it will
be .. because the entire outcome of this mission is to
arrive at a total media disc burning and sharing
strategy among Apple and as a matter of operating
contingency .. XP machines too. Open source
applications in use by us are deliberately cross
platform between XP and Apple machines. Data generated
is able to be swapped or even shared among the machines
with little or mostly no user operating challenges.
Focus on productivity. The media disc(s) burned in the
XP machine reads well in the Apple machines.
The Finder media burned disc .. mentioned above earlier
.. CD-RW .. read immediately on the XP machine .. folder
and data files burned .. all there .. all on display.
99% able to be copied to the XP machine hard disk .. and
confirmed as a CD-R formatted disc since only option is
to erase the disc and not add to the existing content ..
thanks to the Apple Finder format for the re-use sharing
limitations. So Apple SuperDrive cannot read it's own
disc but XP machine can and is able to verify burn by
way of 99% trouble free copy to XP machine hard disk.
Here .. we begin to struggle with what is happening in
our limited media disc burning experience(s).
Enter Media Disc Burning Software
Additional software has become necessary to accomplish
our media compatibility and resource management
requirement(s) .. and we are surely open to your welcome
suggestions for software applications that enhance the
available Tiger OS X applications for dependable
outcomes.
Remembering for a moment that we have arrived at almost
total incompatibility between the two Apple disc media
drives mentioned after burning disc(s) in the Mac mini
using DU and Finder and attempting reading in the iMac
DV SE. We are searching for ways to achieve worthwhile
compatibility.
And one way is to use the XP machine to create data
burned media disc(s) that are instantly able to be
easily read by both Apples in our humble possession.
This fact is an earlier discovery .. when migrating
(again) from the XP realm to Apple heaven. Moving open
source application data files form the XP realm to
the Apple iMac DV SE machine was unencumbered. Easy.
How unprepared we are for the encounter with OS X media
disc burning tools limitations.
We go on-line to seek any worthwhile open source media
burning software for OS X. www.pure-mac.com lists
several possibilities. We need to burn media disc(s)
that are able to be read by a wider population of
computer systems including Apple (OS X) and PC (XP) and
be fully (re-)used to their manufactured storage
capacities. A combination of Finder and Disk Utility,
if you will.
We quickly learn that Roxio is evidently the developer
of the supreme media burning software available to Apple
users. And garner from on-line sources that Roxio is
favoured by the serious and casual user who demands
quality.
For the moment we choose to learn more by trialing less
expensive media disc burning software(s) to find out
whether our simple needs (and open source patronages)
can be met by available applications without unnecessary
bells and whistles. We may be wasting our time here ..
if Roxio or similar is favoured by so many and not
because of the bells and whistles but rather
because of media disc burning performance quality and
standards then we are likely to arrive at that same
destination too. As satisfied Roxio user.

BurnAgain is one of the programs we chose to experiment
with to create more standards compatible media disc(s)
burned. BurnAgain is developed only for the OS X.
BurnAgain automatically and only formats in ISO 9660
(Rock Ridge) .. guaranteeing Windows machine
compatibility. And it does .. so far .. we have used up
about 5 of the available 10 burns before registration
should be made with the author. We learn from the
BurnAgain help system that iTunes burns the same as
Finder.
However, BurnAgain focuses only on CD-R and CD-RW media
.. SuperDrive is capable of more. And you are
discouraged from mixing media disc burning applications
to burn the same media disc. BurnAgain prefers you to
stay the course. DU is the OS X solution to alternate
media burning (DVD) .. but apple OS format only.
However, still our iMac is troubled and challenged to
fully and properly read the BurnAgain media disc(s)
burned (CD-RW) by the Mac mini .. it couldn't .. but
eject was a formality and not a crises recovery
management procedure as before with the DVD+RW disc
burned by DU on the Mac mini.
XP machine could read the BurnAgain CD-RW Verbatim
disc(s) easily and fully .. but copying was about 99%
accurate (same as Finder). We are writing about 350
Mbytes of data files recorded on the CD-RW media disc
with nested folders up to several deep. However,
subsequent burns to disc(s) wouldn't repeat the same
data file errors .. meaning if you noted the delinquent
files then you could just BurnAgain those files and
expect eventual full disc to hard drive copy success on
the target machine (XP in our situation) of those
deliquent datafiles.
Originating Apple Mac mini machine could read the
BurnAgain CD-RW verbatim disc(s) easily and fully .. and
copying was 100% accurate back onto the originating
Apple Mac mini machine hard disk .. all 350 Mbytes of
data files .. no error messages reported. Meaning the
originating machine is performing as expected .. with
BurnAgain .. but sharing remains a challenge with other
machines. Particularly iMac DV SE. Remember that Finder
media disk burned couldn't read again on the Mac mini.
BurnAgain is clearly an improvement of standards based
media disc burning .. since originating Mac mini could
read it's own burn and XP machine 99% accurate too. DU
is OK if you are confining yourself to Apple machines
and they can actually read the media disk burned .. only
originating Mac Mini was able to read it's own burn 100%
MATSHITA DVD-R UJ-845C is the most modern and capable
(Super)drive among the five disc media equipped machines
available here. For now we are confused whether that is
any advantage or disadvantage.
We are going to run through the remaining media disc
burning softwares available from the www.pure-mac.com
website to determine if our simple needs can be met
or whether we are required to plumb for the creme deluxe
(Roxio) and have greatest confidence that our media disc
burning needs are fully met. We may report back our
findings to anyone so interested at this forum. Are you?
We also chose to sample a Verbatim CD-R media disc for
burning and copying of data files among machines.
However .. the BurnAgain burn went well .. but the
copying was problematical to the XP machine hard disk ..
file copy errors .. and back on to the originating Apple
Mac mini machine hard disk too .. Error code - 36 (same
file errors as XP machine). We tried again and met error
messages from the BurnAgain application .. to the effect
that BurnAgain would not permit a further media disc
burn .. even though few hundred megabytes available on
target media CD-R disc. This outcome .. according to
Disk Utility help is because: "Mac OS Extended allows
burning the disc more than once. Formats such as ISO
allow burning the disc only once." Off to the XP machine
and burn an additional small file to the disc. Perfect.
Back to the Apple originating machine .. copy file to
the Mac mini HD. Perfect. Kept the disc for any future
file transfers between the XP to the Mac(s) until fully
used. How confusing .. and .. yes .. frustrating too.
Burnz is the only other program we choose to sample
after studying the homepages and value propositions
and our needs assessment. Thank you to www.pure-mac.com
for the compilation(s) and accessibilities. Appreciated.
Burnz developer www.thinkertons.com have other software
available too. While downloading Burnz media disc burn-
ing software for trial evaluation .. we browsed Burnerz
.. another application from thinkertons that is 100%
free. Burnerz is an informational tool .. and retrieves
whatever informations available on your system about
optical media drives fitted and attached and your
computer systems' optical media drive compatibilities.
Burnerz is a welcome assist for the knowledge starved
and delivered up useful confirmations of the MatShita

Back to BURNZ
Burnz has a particular feature that meets our
requirements and added weight to the application's value
proposition. You are able to choose the specific optical
media disc burn format. Five graduations exist.
Each graduation includes (all) of the lower ranked media
burn format qualities. Top to bottom sliding scale.
HFS+
ISO 9660 Joliet extensions
ISO 9660 RockRidge extensions
ISO 9660 level 2
ISO 9660 level 1
Visually affirmative .. this feature gives user
confidence about media disc burned format
compatibilities. And the website and written materials
from thinkertons make clear that compatibility is well
covered for all optical media drives. Exactly what we
seek. Default is HFS+ which thinkertons encourages you
to maintain unless you do reason to otherwise change.
Finally, for now, Burnz writes DVD media disc(s) too.
Wethinks .. could we go wrong now .. as we progressed to
practical evaluation. 10 free burns before registration
is required by thinkertons. Here we go ..
We chose 407.29mb data files .. application downloads
and Tiger updates (.dmg, .zip, .bin) .. in one folder
to brand new Verbatim CD-R (702.82mb available according
to Burnz) .. and settings to maximum possible speed
(automatically selected at 16x) .. other selectable
speed setting is 8x .. and leave disc appendable ..
verify burned data ON ...
Burn failed...
StatusError: -2147352477
ErrorString: Verification of the burn failed
RE-inserting the media burned disc gave desktop CDR
icon with the burn folder named and 406.9 MB usage ..
Finder (double click on the desktop disc icon) shows
all 18 items burned .. copy from CDR back to new desktop
folder showed the appropriate copy dialogue box and
progress bar without color .. left awhile to see what
happens ...
The Finder cannot complete the operation because some
data in "Gimp-2.2.8.dmg" could not be read or written.
(Error code -36).
Error code -36 is becoming an old friend ..
Repeating the operation minus "Gimp-2.2.8.dmg" ..
same drill .. offending file "MacOSXUpdate10.4.3.dmg" ..
repeating minus "MacOSXUpdate10.4.3.dmg" .. same
drill .. repeating minus "PDFLab.dmg" .. that's three
out of total 18 so far .. and not one copied from disc
to desktop .. last chance before coaster designation
is applied as we get the pattern and the picture ..
down to 245.9 MB to copy and still no satisfaction ..
and now number 4 "Firefox 1.0.7.dmg" ..
Houston .. we have a coaster .. trajectory .. garbage.
Won't bother trying this disc insert into the iMac.
However, we troubled ourselves to find out what would
happen in the XP machine .. same outcome .. yes,
readable by XP but copy failure to hard disk on the
larger .dmg files. Not unexpected. Media format
compatibility confirmed .. just as Burnz promised.
Repeating the entire exercise with brand new Verbatim
CD-RW (just to reduce CDR coaster count) .. this time
at 4x write (automatically determined with no other
speeds selectable - maximum possible) .. all other
settings unchanged ... samo .. samo ..
Burn failed...
StatusError: -2147352477
ErrorString: Verification of the burn failed
RE-inserting the media burned disc gave desktop CDRW
icon with the burn folder named and 406.9 MB usage ..
Finder (double click on the desktop disc icon) shows
all 18 items burned .. copy from CDRW back to a new
desktop folder showed the appropriate copy dialogue box
and progress bar color .. copy began immediately and
reached the end .. Bingo .. we have a winner ! .. or
do we ? .. Opening 50% of the now copied to desktop .dmg
files produced an error message: The following disk
images failed to mount. And for each delinquent .dmg ..
the same Reason: codec overrun .. quite whatever that is
meaning .. we appreciate the .dmg is damaged and now
useless. Always the larger .dmg files .. up to 125 MB.
On the Apple .. we are down two for two .. let's go
again with burn verification off .. but first erase the
disk with DU quick erase .. done .. now regarded again
as an empty CDR by Finder .. (note that 'Erase disc
before burning' is an available option in Burnz and on
the Burn Disc dialogue box .. but it wasn't available
as soon as the previously burned media disc was
re-inserted for deleting and re-burning) ..
No burn failure message .. as expected .. 406.9 MB
usage on CDRW .. as expected .. Finder shows all
18 items burned .. copy to desktop .. seemingly
good .. as before and usual .. opening .. again
a 50% failure rate .. same message .. same result.
And in the XP machine .. same for read and copy to HD.
OK .. let's give it one last go with the .dmg's, .bin's,
and the .zip files .. by erasing again (with DU again)
and media disc burning the CD-RW with just one file at
a time and then copying back to confirm burned file
integrity .. that's totally 18 burns .. but we shall
only go as far as 9 file burns and copy back to the
desktop from the burned media disc .. if all 9 are
good then we shall assume it would all be good. We
trial the big .dmg's to begin .. interestingly, erase
disk before burning is available now and so we use
that feature rather then DU (perhaps because the
burn is less than the remaining disc storage available)
.. is that a bug ? we wonder .. we turn Verify burned
data ON .. just curious .. we are asked about our erase
certainty before proceeding .. we click yes ..
burning .. 97 MB .dmg .. burned (no negative
verification error message) .. now copying back to
desktop .. opening .. and .. codec overrun message.
Finally, for now, we return to our original evaluation
folders and files trialled with BurnAgain .. and perform
the same media disc burn and onto the same (new) media
disc (i.e. CD-RW) from the same batch too .. using Burnz
.. Verify ON ...
Burn Failed ... blah
Copying back to desktop .. copy back is good .. just
like BurnAgain .. encouraging.
What that says about the larger .dmg files or perhaps
any larger (50mb+) files to burn is unclear .. do you
need even better hardware (media and burner) and
software ? .. or are you out there in expert land able
to advise readers how you do exact maximum confidence
on the larger files media disc burn(s)?
No DVD media burn disc(s) lying around here, for now,
so we shall reserve any outcomes for another day of
evaluations and experimentations.
BurnAgain and Burnz go head to head .. From the tests
performed to date we are able to comment from personal
experimentation and practical experience .. they are
very much similar quality .. Burnz does DVD's too.
However, neither managed to accomplish entirely reliable
media disc burn(s), of use, beyond the originating Mac
mini SuperDrive .. nor accomplish verification .. is
that normal ? Or do we have a particular problem ?
We are back to square one for verifiable media disc
burning.
Interestingly .. those 10 free media disc burns
available .. have only reduced by the number of burns
without verification .. since negative verification
appears to not count .. 8 free burns still available ..

We are safely at the point where we can assert that we
have a potential operating solution for the Mac mini
media disc burning. However, we remain reliant on our
XP machine to create media disc burned that can be read
fully by the iMac DV SE. And we have no confidence to
date in the ability to share information burned by the
Mac mini with any other party .. except where we can
repeat ourselves over several iterations to accomplish
100% data transfer .. and that means we are confined to
our home operating computer systems. For now, XP machine
is required to write a media disc that can then be read
by the iMac DV SE. (Yes, we do have a Mac to Mac network
.. but if data is unavailable on either of the Mac
machine drives then we are required to resort to hard
media backup) Media disc(s) sampled to date .. Verbatim

at www.apple.com and in our locale. We shall sample the,
not inexpensive, apple media disc(s) in the near future
.. and report back. Still the DVD-R is write once. And
no mention of any CD-RW apple quality media
availability. Remember ...
*• DVD-R discs hold about 4.7 GB of information.
You can burn files on a DVD-R disc using the Apple
SuperDrive. DVD-R discs are not reusable; you can burn
files on them only once.
[1] Action item one is to acquire genuine quality media
disc(s). [ to, ideally, accomplish burn verification ]
If 100% media disc burn and verification were able to be
accomplished by the OS X supplied applications Finder
and Disk Utility then only limitations to overcome are:
Finder's (improved standards adhering) write once only
to media disc feature and Disk Utility's apple OS only
media disc burned format limitation and maybe multi-
session disc burning feature.
[2] Action item two is to acquire genuine quality media
disc burning software(s). [to accomplish burn media
capacities and maximum standards adherences ]
If fuller standards compatibility and media disc burn
usage features are available then items one and two
requirements seem to be met. And actions items three
and four are no longer options of any material
significance. That would be welcome.
[3] Action item three is to optionally acquire an
alternative media disc burning solution. [ to accomplish
100% or nearest possible media burn quality and
consistency ]
[4] Action item four is to forego media disc burning
(item three) in favour of external hard disk solution
(which could be partitioned) to share datafiles among
differing machines and operating systems. [ to resolve
the media sharing challenge in the absence of
satisfactory value media burning solution that meets
quality, consistency and compatibility needs ]
Hopefully .. this tale of media burning discovery does
ignite some passion and interest among certain others of
you who may be willing to share a little of your own
enlightening discoveries in the industry of media disc
burning and any Apple SuperDrive MATSHITA guidelines or
guidance(s) that you have established .. in particular.
For now .. and until any further future update .. thank
you again everyone .. we look forward to any remedial
solutions that you may have developed to your media disc
burning operating satisfaction. Much have we to learn ..
search for answers continues ...
Well .. it's been fun .. in an adventurous and discovery
kinda way .. but back to our chosen path must we return.
Stuart.
Additional Informations ...
We only ever used the software system default media disc
burning speed settings where no choice permitted, or
where choice permitted .. we used half (the
automatically selected ) speed setting or lowest
possible speed setting.

Unable to Load Metadata (Error in shared.context.ContextLoader in startup)
Hi,
I am currently installing fixes on an environment, and every time a patch was installed the application server starts up. The application starts up successfully until I installed 8424662. I still don't know if this is the patch that causes the error, but here's the part of the log that states the error:

Any help on this problem is greatly appreciated. Thank you so much!Patch 8424662 incorporates an entry in contextManagedObjects.xml that points to a class com.splwg.base.domain.common.masterConfiguration but this class is not yet present in spl-base.jar file. Patch 8711158 should be installed, since it contains this class.

We have a group of 5 people editing and indexing photos to a shared drive on a windows server, everyone has its own catalog and working on different folders to avoid any locking conflicts.
The windows computers don't have any problems but the Mac's don't write the updated metadata to all files because they get the message "Photos have read-only access".
The environment is the following:
2x Macs workstations running:
- Adobe Photoshop Lightroom 5.7.1
- iMAC with MAC OS X Yosemite 10.10.2
3x Windows Workstations:
- Windows 7
- Adobe Photoshop Lightroom 5.7.1
Server:
- Shared drive on a Windows Server 2012 Standard
I have searched the internet, no one has this problem with this exact setup but I have tried all the solutions I found, namely:
1. Connect to the network drive with cifs:// protocol
2. Change the settings of the nsmb.conf for 'smb1_only' protocol
3. Mount the drive manually by command line
Nothing worked, any ideas?Did you ever find a solution to this problem? I have the same issue and wonder if Lightroom 6 will resolve it. I tried AFP, SMB2, SMB3 and they all failed to save metadata randomly. When I use NFS from OS X then it works fine but it's a little slower than SMB and it's not as native as the mount via AFP or SMB, so it's harder to maintain. My server is a FreeNAS 9.2 (FreeBSD) which is running Samba, Netatalk and native NFS.

Editing and sharing custom metadata/keywords through Adobe Drive in Adobe Bridge
I am part of a four-person video production unit operating within a local governmental entity. We are currently using four licenses of Adobe Master Collection CS5, and are about to get access to dedicated SAN storage.
We would like each user to have the ability to assign specific keywords to any given video clip (or remove keywords from clips) within Adobe Bridge, and have the three other users see the same results. I've noticed that Bridge alone will allow for keywords to be added or removed, but this list is specific to each user. Importing one list into other users' profiles is a start, but would no longer work, once keywords are added or taken away.
The overview page for Adobe Drive 3 says that it, "allows users to edit and view custom metadata/properties through Adobe Drive in Adobe Bridge," but I haven't found any explanation in either the website, forums, or user's guides that delves any farther into this area. If we incorporate Adobe Drive/Bridge into our workflow, will we be able to share/sync keywords between users? Is there some other (affordable) solution that would let us do this?
Thanks for any insight you might be able to offer.
ChuckHi,
Thanks for sharing your case.
The keywords you mentioned is XMP metadata, if all your digital assets are managed by ADEP CQ DAM service, you can use AD3 with built-in ADEP connector to communicate with the DAM server, then, I think it can meet your requirement, it means, the keywords can be set by one user through metadata panel in Bridge, and can be viewed by other users.
for custom properites, it's different from XMP metadata, it refers to the properties of one asset which is managed by a Content Management service. users have to use another UI to edit/view them in Br after AD3 is installed.
here are some requirements to use it.
1) CMIS 1.0 compiliant server should be used to manage all your digital assets
2) use the built-in CMIS with AD3 to connect to the server.
if other kind of servers are used, you should develope a custom connector through AD SDK to enable custom properties feature as well as some other handler required by AD SDK
thanks -
Can IPTC metadata be included in Shared Photo Streams?
I was surprised that my version name and all IPTC data such as my ratings, key words, etc. are not appearing in my Shared Photo Streams. Is there any way to include this metadata?
Since you are seeing the Shared Photo Stream Albums in Aperture, but empty, you have all preferences set up correctly.
Aperture or iPhoto should be filling the albums from the folder I mentioned, but they cannot, because this folder is empty.
There may be two reasons for this folder being empty. Either the Photostreamagent is not running or you may be having a permissions problem with your home folder.
Have you tried to toggle the Photo Sharing off and on again in the System Preferences, as described here in this link? iCloud: Troubleshooting iCloud Photo Sharing and Shared Photo Stream
You could also try if removing the empty folder ~/Library/Application Support/iLifeAssetManagement/assets/sub-shared and restarting the Mac will help.
As a test you could try, if the Shared Photo Stream will work in Safe Mode: Mac OS X: Starting up in Safe Mode
If all fails, launch the Console from the Applications folder and check, if there are any error messages relating to "photostreamagent". -
Sharing to flickr doesn't push the metadata of modified photos
In iPhoto 09, we can share photo on flickr.
There is a very annoying problem though. If a photo has been modified in iPhoto, the metadata is lost (well, it's not lost really, since it's kept in a database outside of the file) but the file corresponding to the working copy of the photo doesn't contain the metadata of the original file. Although this is very annoying for many reasons, I understand that one photo in iPhoto is not necessarily 1 file. Fine.
The problem is that contrary to when a photo is exported, the metadata is not added to a photo that is shared on flickr (using the new 09 "share to flickr feature").
It works correctly when sharing on facebook though.
Here is a very basic scenario:
Take a photo in "landscape" mode and another in "portrait" mode.
Import them in iPhoto. Normally, the one in "portrait" mode will be rotated automatically by iPhoto so that it is displayed as it was meant to be display (great).
Select those 2 photos and share them on flickr.
The one in portrait mode will not have a "date/time taken" so the value will be the same as for "date/time uploaded". The one in "landscape" mode should be fine.
I think this is because the file that is shared for the picture in landscape mode is still the original file while the one for the portrait photo is a working copy that doesn't contain the metadata.
Is this a bug? Any chances to get a fix?I believe so.
I have done some more tests and it looks like only the photos that have been rotated automatically because they were taken in portrait mode are affected.
For example, the pictures that I have modified in iphoto are exported AND shared on flickr with all the metadata. So it is not a matter of having a working copy of the original photo or having the original photo file.
It is really only for pictures that were taken in portrait mode.
I have done this simple test:
I import a photo that was taken in portrait mode, and export it with all the possible information check box checked (including location)
=> the exported photo doesn't contain the "generated date" and contains very little metadata (it does contain the location though).
I then go back to iPhoto, and "revert" the photo "to original". It doesn't appear to change, and it still is displayed in portrait mode. But now if I export it, the export contains the full metadata.
If I export a photo that got heavy modifications but that was taken in landscape mode, all the metadata is there.
So it really looks like a bug related to the "portrait" automatic orientation. The metadata is lost somehow... -
Displaying Album Usage/Sharing Metadata
I know this has been asked before, but I was wondering if anyone knows how to display in the Metadata Inspector tab, which albums might contain a selected image. The reason I ask has to do with posting images to Facebook for example. Working with a project containing many images, I selected a number of them to be published to Facebook. Essentially this creates an "album" containing these images. At a later date, I might want to add additional images from this project to the Facebook album. Looking at all the images in the project, there is no way of knowing if a certain image has already been published or not. I know you can use the Sharing Metadata View in the inspector which tells you if a selected image has been shared or not. This works only for the Facebook "Album" or other published albums. There is no corresponding way to know if a selected image is in any other type of album by using the metadata inspector. I know you can filter the images by using the Aperture metadata field "album name" with any of a number of conditions, which does provide the information. However, as far as I can know, you can't display the Aperture metadata field "album name" in the metadata inspector. Am I understanding this correctly?
Thanks!!
