IPTC Core metadata fields lost with PNGs

Hi there,
I have a TIF file which contains data in the IPTC core fields. Converting the TIF to a JPEG will retain most of the fields and can be viewed still in Adobe Bridge.
However, converting to a PNG will lose all of the data. The only way it seems to retain metadata is to set options on the Save to Web options in Photoshop, which doesn't really work too good with a 100mb TIF being converted.
Resampling to PNG in ImageMagick and then reading in Bridge has the same issue, even though 8BIN and IPTC profiles are actually embedded into the file.
Does Bridge support IPTC core metadata for PNG files?
Many thanks!

They've confirmed the same thing i've found, that Save For Web actually preserves a chunk of the IPTC core data, but this isn't really any good for the quality of image I need to save.
It's strange how the XMP preserve option isn't available for a standard PNG save.

Script to add content to IPTC core metadata fields

Is there the possibility that a script could be used to add data to IPTC standard fields?

Do search engines make use of IPTC Core metadata?

I'm using Bridge to organise a large group of maps (the maps are JPEG images), which will be published on my organisation's website. These maps are about niche topics and very specific areas of the UK.
I'm wondering if there are any SEO benefits from adding IPTC Core metadata to these map images using Bridge? Does anyone know if search engines use the meta?
Thanks in advance for any ideas.

Thanks for the replies. Yes, I'm talking about whether Google etc. pay any attention to the meta in the images.
My map images are exported from the source map application as JPEGs.
I'm not using a batch 'Save for web' in Photoshop, as the map images aren't designed for viewing in web pages - I'm just putting the maps up on the web to quickly share them for re-use by other people.
In Bridge, I can quickly add the basic meta (copyright notice, addresses, rights usage terms, etc.) by selecting all the JPEGs and then do the title and description individually. Just wondering if it's worth the effort?

IPTC field codes -- Bridge IPTC Core metadata

Is there a reference somewhere as to which IPTC codes match up with the IPTC Core fields in Bridge metadata?
A list of the codes is here, so you know what I'm talking about. For example, the Description field in Bridge metadata corresponds to the Caption / #120 code in this list:
http://www.fotoware.com/binaries/fsp50/userguide/28.htm
I'm using a plug-in that writes image info from a database into the corresponding file's IPTC fields based on the IPTC code, but the names of the fields on the list of codes don't match up with what they're called in Bridge, so it's taking a lot of trial and error to figure out where things go.

Never mind, found one. It doesn't mention Bridge specifically, but it has Photoshop and Lightroom (along with several other image-browsing apps) and both seem similar to Bridge:

Display the filed instructions (that´s under IPTC Core metadata).

Hi all
I´m new on programing scripts in Photoshop..and tried everything but was not able to change the script below. Let´s explain this script is found at Adobe Photoshop default folder and works to show the Camera Model used to the current image.
Now..the challenge...I want to change the scripts so when you run the it shows a field called Instructions (that´s located in the IPTC Core XMP metadata Tab. (In Photoshop > open an Image > go to File menu > File Info option and see the IPTC Core Tab > Instruction field).
Can anyone please help me to change this lines. It could look very simple for you but it´s actually very difficult to me; This base-script is what I have and works fine to display the camera model:
try {
     var xmpString = activeDocument.xmpMetadata.rawData.toString();
     var tiffModelLength = ('<tiff:Model>').length;
     var tiffModel = xmpString.search( '<tiff:Model>' );
     var tiffModelEnd = xmpString.search( '</tiff:Model>' );
     var tiffModelStr = xmpString.substr( tiffModel + tiffModelLength, tiffModelEnd - tiffModel - tiffModelLength );
     if ( tiffModelStr.length > 0 ) {
          alert( tiffModelStr + localize ( '$$$' ) );
     // check the exif
     var exifModelStr = '';
     var exifData = activeDocument.info.exif;
     for ( var i = 0; i < exifData.length; i++ ) {
          if ( exifData[i][0] == 'Model' ) {
} // try end
catch( e ) {
// always wrap your script with try/catch blocks so you don't stop production
// remove comments below to see error for debugging
// alert( e );
Thank you a lot for any help.
Gustavo.

Here is one of X's functions that should give you the information..
#target photoshop
var xmp = activeDocument.xmpMetadata.rawData;
var Instructions = parseMetadata(xmp,"photoshop:Instructions");
alert(Instructions);
function parseMetadata(xmp, tag) {
var re = new RegExp('<' + tag + '>(.+)</' + tag + '>');
var m = xmp.match(re);
if (!m) {
    re = new RegExp("<[^:]+:" + tag + ">(.+)</[^:]+:" + tag + '>');
    m = this.xmp.match(re);
return (m ? m[1] : '');

Filtering on IPTC Core

Hi guys,
Is it possible to customise the filter eg. to use any of the IPTC Core fields? or is it possible to search for specific fields in IPTC Core? Can the filter categories (filter pane -> icon top right) be modified? I don't use the ones listed. Can the search criteria list be modified?
Specifically, I've been hoping to use the Country field of IPTC Core and then filter by it; but if this can't be done I could start putting countries in as keywords?
The nearest I've found is to use the All Metadata criteria in Search.
Ben

yeah, thanks Curt. It seems that way.
Similarly, I note that only some fields are available in the thumbnail view, and some of the IPTC Core metadata could be useful here too.

Copy file name to IPTC (core) Instructions

Hello
In the past Paul has written some great scripts to autuomate my Bridge workflow. I'm hoping for another brilliant concoction.
I wish to copy my file name to the IPTC core- 'Instructions' field so that the original name will be preserved somewhere in case renaming more than once wipes that file name out of the File Properties palette.
Thanks!
Don

I have Bridge CS2 and CS3 and for some reason the CS3 version has the "Preserve Filename..." checkbox grayed out and I cannot figure out why. I was also looking for a way to view the "Preserved Filename..." and the only way I could do this was by using Bridge CS2 (since it isn't working for me in CS3), going to rename the file I am trying to view the old name on, and select "Preserved Filename" under the dropdown menu. This is a huge hastle and for some reason Lightroom 1.0 does not have the capability of preserving filenames at all! The DAM capabilities of Lightroom truly need work, but it is a wonderful application nonetheless, and I use it now for everything and haven't needed to use Bridge since I got Lightroom.

UCM Metadata modeling - Complex metadata field

Hi,
We are currently in the process of modeling our UCM for our enterprise webcenter application.
We have a requirement where a metadata field may have non-straigthforward values.
We have a table called worklocation_table with rows of data such as
Columns : | doc id | office | city | province | country
row 1 : | 1 | 12 Ave | NY | NY | USA
row 2 : | 1 | Buffalo | NY | NY | USA
row 3 : | 2 | Stn 2 | Edmonton | AB | Canada
We want a metadata field xWorklocationMetadata which associates a document with a one to many relationship with worklocaton_table.
So if we have a docMeta table in UCM
Columns : | dId | xWorklocationMetadata
row 1 : | 1 | 1
row 2 : | 2 | 2
But the problem will be with searching ? How will the search understand a foreign key relationship between docMeta and xWorkLocationMetadata ?
How should we approach our modeling ? Are they any features in UCM that will allow us to do that. Our main concern is
searching, metadata management and ease of development.
Thanks,
Sunil

How about changing your database scheme a bit?
a) one table (documents) with the primary key dId - in fact, dId is for revisions, not documents, but be it
b) the other table (worklocations) with its own primary key - No doc id there!!! (it is not a property of the worklocations, but of a document, or of a binding)
c) the third table (binding) which will contain many:many relationship between docs and locations (your data suggests that the relationship is rather many:many rather than one:many as doc_id 1 is in both 12 Ave and Buffalo; one:many would actually be even easier)
Now, the third table can be replaced by a custom metadata; one:many is a peanut - each doc is in just one location, so you can add the location as a metadata field. With many:many, it could be a bit trickier - OOTB you could go with Multiselect List, but if you have a lot of worklocations, the user experience might be too bad. Therefore, probably some customization (and why not keeping the binding in a separate table, then?) would be needed anyway.
Either way, check what schemes http://docs.oracle.com/cd/E23943_01/doc.1111/e10978/c04_metadata.htm#DAFEDBBA can do for you.

Raw files (CR2) - Cannot modify IPTC Core fields, get error messages

I really hope someone out there can help me out here because I'm at my wit's end!!!!
I have a bunch of raw files in a folder, these are just pictures I took for a bit of general practice over Christmas.
Now, whilst trying to modify the IPTC Core Fields (basically adding my name and my email address to the pictures), it worked fine for most of the pictures, but for some reason it will not work for the last 20. This is driving me nuts. :(
The first picture which doesn't work was taken literally 2 seconds after the last one which does work. All pictures work perfectly well in Photoshop, I can open them, modify them, save them as jpgs... no problem. But it just won't let me change the metadata. The pencils on the IPTC Core fields are nowhere to be found, the option File>File Info appears greyed out... etc.
The error messages I get:
1. When clicking on any line of the IPTC Core Fields (such as "Creator") =
i "This property cannot be modified".
2. When clicking on the keywords tab and trying to enter keywords =
i "The file Name.CR2 cannot store XMP metadata. No changes will occur"
I have scoured the web for help, visited multiple forums... to no avail. It looks like other people are having the same problem but no-one seems to have a solution. I haven't done anything different to those 20 pictures, so I just can't think of a logical answer, it just doesn't make sense!!
I am only starting to catalogue my pictures in the hope of going professional one day and this is extremely discouraging... if anyone out there can help, I'd be ever so grateful. Right now I just feel like pulling my hair out!! :'(
OK, rant over :)
Thanks very much for reading and thanks very, very much in advance for any suggestions/ideas!!

I have run into the same problem. I downloaded photos in raw format ".CR2" from a Canon 40D via a compact flash card reader to my laptop. I labelled the ones I wanted green and then transferred these images via wireless transfer to my desktop. I had not checked any keywords while these were on the laptop. I used the Bridge (CS3)File/Copy to menu selection to effect the transfer. Both systems are Windows XP, SP2.
I then tried to check a keword in my list for an image and got the error message number 2 reported by Maria Atkins above. I got the same for all images on the desktop system.
Observations:
-the green labelled items are correctly filtered on the desktop, but the labels on the images all show white.
-not all images even have .xmp files associated with them. It appears to be a random thing.
-although I have checked my preference to have double click open an image in Camera Raw in Bridge it will not do so with these images, always opening Camera Raw in Photoshop.
-the camera exif data is correctly attached to the images, whether there is a .xmp file associated or not.
-On my laptop I found I can check keywords and they are stored with the image with no complaints from Bridge, and whether the image has a .xmp file associated with it or not. This is after I had copied the images to the desktop. I was just checking whether the problem was with the original images or just the transferred ones. It appears to be that something was not done correctly in the transfer.
This is not a trivial issue since it is essential for cataloging images to enable future searches. I hope someone from Adobe is paying attention and will respond with an answer.

Automatically populate metadata field with file name?

Hi, I'm not sure if this is possible...
I'm working with many large batches of .jpg files, and am running them through Bridge in order to add metadata according to my client's guidelines.
For every single file, my client requires that the "Description" field in the IPTC Core section of the metadata is filled with the full filename, as it would appear in the Finder, including the .jpg extension.
Currently I'm copying every file's name and pasting it into the Description field. Does anyone know of a good way to automate this task? Since each file name is different, a standard metadata template isn't meeting my needs.
If anyone knows of a good way, I'd be very glad to know! Thank you.

Awesome, That works really well.
I found this on the forum based on your answer.
Puts the file name in the field and takes off the .pdf extention.
var
fileName = event.target.documentFileName;
//removing the file extensionvar vDot = fileName.length-4;
//apply the value to the TxtFieldthis.rawValue= fileName.substring(0,vDot);

Loading metadata via iptc core using Bridge

I've noticed that after loading metadata into photos opened in PS (cs5) that when checking the "file info" for that photo, the metadata isn't showing up. Wonder what I should do differently?

Does checking the "apply" check mark actually SAVE the photo with the newly applied metadata?
It took me a while to understand your workflow but you seem to use the metadata workspace and with apply you mean the tiny green checkmark icon bottom right in the metadata panel, which is not the same as a template btw, you can create a template with basic info using the little menu icon top right in the metadata panel. Changing this template every time would not be needed if you use the panel itself on multiple selected files.
You can either choose to add the template upon import using Photodownloader or select the files and choose add template from the same drop down menu top right of the panel.
Then you can use the fields in the panel itself to add extra data (besides the basic copyright info e.g added with the template) for the selected files in one go or select a given number that needs other info.
I never used it that way before but yes, when having filled all the wanted fields with your custom data you can indeed use the green checkmark and this should save the info to the files that are selected.
You have to have read and write permissions and the files shouldn't be locked.
But instead of the tiny icon in the metadata workspace (to my opinion a next to useless default workspace that can't be altered the way it should be possible) I always use my custom workspace (large preview, large content panel with larger thumbs, a column with folders, filter collections and favorites and a metadata panel with IPTC core in view) and after having filled the lines I want I hit the enter key to save the changes.
As said, only the selected files are saved with the data and you have to wait for the activity bar (bottom left) to finish the job before starting a new one because sometimes this causes half of the the files not being saved with the correct and complete info.

Search the IPTC metadata field "Source" in Lightroom 5?

How is it possible to search for photos in Lightroom 5, where the IPTC field "Source" is empty? Is it possible to add additional metadata fields to the Library Filters?

The only way to search the IPTC Source field in LR is to use the "Searchable IPTC" criterion:
This searches all the "searchable" IPTC fields (Adobe doesn't specific exactly which fields those are, but they do include Source).
However, you want to find photos whose Source field is empty. LR doesn't have an "is empty" criterion for most fields, but the normal way you'd work around that, e.g. for Title, is to do:
Title Doesn't Contain a b c ... x y z 0 1 2 3 4 5 6 7 8 9
Unfortunately, that workaround won't work in your case, since
Searchable IPTC Doesn't Contain a b c ... x y z 0 1 2 3 4 5 6 7 8 9
would only return those photos all of whose IPTC fields are empty. If there was a photo with a non-empty IPTC Headline and an empty Source, this criterion wouldn't return the photo.
To search the Source field in particular, you'd need to use a third-party plugin, e.g. ExifMeta, Data Explorer, or Any Filter.

Custom metadata field with autonumbering sequence

I have created a custom metadata field and I need it to be able to start a zero and then increase by one with each checkin. There were other qualifications for this particular field as well, which I have managed to do. Currently, the field is V99_99999 where V is a constant, and the 99 immendiately after the V is the current two digit year. all that works great. the issue I am having is with the second half of this. I have it going against the content_id currently, which is at 003856 right now, so when I check in my first content, it will look like V09_003857. what I need it to look like is V09_00001 and then increase by one with each checkin, and then for the really tricky part...when the year changes, on Jan 1, the counter needs to start over at all zeroes again.
I am fairly new to UCM and this seems huge to me. I purchased a book called "The Definitive Guide to Stelelnt Content Server Development" hoping to find the answer, but am still struggling, so I am using another life line and reaching out to you all.
Thanks,
Patti

Interesting!
You'll need a component. You already mentioned you had a custom metadata field. You will also need to add a counter to the counters table for your component. During a check in you will need to fetch the next value from the counters table, increment the counter and store the new number back in the table. The year portion of the id is easy, get the current year and grab the last two characters. Then, put this all togther to get the data for your metadata field.
The big question now is where in the check in process will you do all this? You will need something called filters probably. Maybe addFiles, maybe validateStandard, there are several that this could work with.

XMP metadata lost in PNG files

Hello,
My XMP metadata is lost from a PNG file if the file is modified and saved. Here is what I am doing
1. Put some metadata in a PNG file using m_xmpFile.OpenFile( FileName, kXMP_PNGFile , kXMPFiles_OpenForUpdate)
2. Edit this file in Photoshop (changed the brightness and contrast of the file)
3. Saved the the modified files.
All my XMP metadata is now lost fromt the file.
is my implementation wrong? Is there some other way to stamp metadata in PNG files?
Thanks,
Hitesh

Info: Mac, Yosemite, Bridge CC
I have an extensive collection of PNG files that HAD been keyworded in Bridge (XMP). I noticed several days ago that the XMP of all those files is now missing.
When attempting to assign keywords back in, I also get the message: "The file ####.png canot store XMP metadata. No changes will occur." Weird. Like you said, it's looking like a bug.
And here's the kicker... if I duplicate the PNG file (Edit > Duplicate), the "copy" DOES contain the original XMP that went missing.
I really don't want to have to manually duplicate all my PNG files just to regain the metadata. Any brainy solution? I'm attaching an example of the original PNG (missing XMP) and the duplicated PNG (magically restored XMP).

Is there a way to sync my IPTC Core "date created" with my File Properties "Date File Created" for m

I am working with a massive file of images and part of the issue is that I need to match the Date Create in the IPTC Core to that of the File Properties "Date File Created" for each image. Is there a way to do that automatically?

The date data is complex. Read through this post and see if it sheds any light on your question. http://forums.adobe.com/thread/1171910
