Crawling xmp metadata from pdf's

We have some PDF files which we are crawling in. These PDF's contain XMP metadata tags. I suspect that the PDF accessor is ignoring these tags. We've tried a number of different proprty mappings all to no avail.
Has anyone else had any luck crawlingin XMP generated metadata?

Hi,
The same code for reading other formats will go for Pdf too.
Only difference is while reading PDF it is not calling any smart filters.

C++ code to get XMP metadata from pdf files ??

Hi,
I am new to this field and now I have to write a C++ code which will read the XMP metadata from any pdf files. Could anyone please tell me how to do that or where to start? Is there any sample code available for that?
I am reading the Programmer's guide and XMP specification to have the whole idea.
I really appriciate your help. Thanks in advance.

How to import XMP metadata in pdf

Could you please explain me, how to import XMP metadata in pdf file through "Live Cycle ES"?

Yes, with LiveCycle ES (almost) all services can be invoked from any of the available endpoints (watch folder, EJB, WebService, etc).
In this case since the ImportXMP requires two input files (the PDF and the XMP) you will need to drop a directory containing both of your files into the watch folder (not the individual files). This is because several requests can be dropped into the watch folder at the same time and without the sub directories LiveCycle couldn't tell what XMP when with what PDF.
A com.adobe.idp.Document - AKA: Document - object is one of the common object types used across all LiveCycle products. When you deal with PDFs and many other binary file objects they are stored a Document object. It is more important that you know this when using Workbench, web services or the Java API.
You should have a look at the documentation at: http://livedocs.adobe.com/livecycle/8.2/programLC/programmer/help/001553.html

Ideas about viewing/displaying XMP metadata from Reader ?

Hi,
We are using Acrobat 9 to add XMP metadata to PDF documents.
These documents are viewed by the others employees with Acrobat Reader.
Since "File->Properties->Advanced Metadata" and "Custom Info Panels" are not available in Reader, how can we display XMP metadata ?
Do you know some ways or plug-ins to do this ?
Our custom XMP metadata schema have more than 20 fields, so I don't want to put all these informations in the "Keywords" field of the document properties.
Any idea would be greatly appreciated !
Thank you !

Michael... what you are describing above is not accurate. The iPod Classic does NOT have the capability of using the "Album Artist" field from iTunes to sort music. This particular metadata field is not even available to the iPod Classic. Only the "Artist" field is available. (It is the other way around with the iPod Touch, iPhone, and Ipad -- for these iOS devices, the "Album Artist" field is the one that is available, and not the "Artist" field.) There are numerous posts here in the discussion forums from other folks who are frustrated by the same issue. The iPod Classic can only sort and group songs together by "Artist" -- that is, the track artist. And the track artist is often quite different from the album artist. For example... I have 29 different Barbra Streisand albums in iTunes. For all of them, the album artist is "Barbra Streisand." There are several different track artists however. Most of them are just Barbra Streisand. But she also does a duet or two on several albums. So there are track artists like... "Barbra Streisand with Kim Carnes," and "Barbra Streisand with Barry Gibb," and many more like that. After syncing to my iPod Classic, when I sort on the iPod's "Artist" field, I get about 25 different iterations of "Barbra Streisand and .... " as the artist. Yes, "Barbra Streisand" does appear among them. But the only songs that are listed under "Barbra Streisand" are those that she sang by herself, and where she is the only track artist. Given the setup of the iPod Classic as it is now, using firmware version 2.0.4, it is NOT possible to use the Album Artist field to sort and group songs together.

Extract metadata from PDF

Hi all
Maybe the wrong category to post this question but I am wondering if it is possible to extract the metadata from PDF document as well as we do from images?
Since both metadata are based on XMP from Adobe it should theoretically be possible. Anybody knows how?
Thank you.
Nitai

XMP extraction from PDF format files is not implemented by interMedia.
You can learn more about XMP at the Adobe web site. It is possible to create a simple XMP extractor by implementing a byte scanner that looks for the XMP indicator string. However, I believe that the PDF format allows for some object blocks to be marked old or superseded by newer blocks. Thus it may be possible to have more than one XMP block in a PDF file. You would need to know more about PDF format to determine which is the current block.

Extract XMP metadata from specific Photoshop Layer in After Effects

How do it extract XMP metadata from specific Photoshop Layer in After Effects?
I am just getting my hands dirty with metadata.
I know it is possible to attack metadata to a layer/layerset in Photoshop, but how to I get it out in After Effects.
Here is the process.
I create BunchaLayers.psd.
Using the PerLayerMetaData.jsx file attached.
I use the setCommMetadata("something") function to attacked metadata to a selected layer.
I know that is is there because I check it using the exportLayerMetadata().
I save and imprt BunchaLayers.psd into AE as a comp.
Here I am lost.
I select my layer in the project window and check the XMP metadata window.
I can't find my comment.
Is the XMP data actually attached to the layer I imported in AE?
I want to be able to select the layer and see that the data is attached. Is this possible?
If it is will it work on layersets (comps in AE)?
I would appreciate any layer specific XMP insight.
Thanks for looking.

John Nack on Adobe : Per-layer metadata comes to Photoshop
This was the article that made me think this might be possible.
There is also the preference to Create Markers From Metadata
["Metadata"]
"CreateLayerMarkersFromFootageXMP" = 01
Which made me wonder if there is a way to create the metadata in the first place that made it something AE would read and automatically change to layer markers.
Any ideas?

Import XMP Metadata From File

In Beta4, the Import XMP Metadata From File command would import data found in an xmp file.
In V1, it's not working...or am I missing something.
(I do understand that Export XMP to File will write the data into the image file itself.)
Ideas?

Here's a sample xmp I created...in case it's wrong..but it was working in B4. <x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Toolkit 3.3-016, build -num-, -date-"> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <rdf:Description rdf:about="" xmlns:dc="http://purl.org/dc/elements/1.1/"> <dc:description> <rdf:Alt> <rdf:li xml:lang="x-default">: Geese at sunset.

XMP metadata from Premiere Pro

I have installed on Mac OS X:
Extension Builder 3 in Eclipse
Adobe Premiere Pro CC
Adobe ExtendScript Toolkit CC
Working on basic example extension project I want to exchange XMP metadata to/from Adobe Premiere using ExtendScript.
I added line to load XMP library in .jsx file, but it doesn't work:
ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
I also tried to extract AdobeXMPScript.framework file from Adobe Bridge installation package contents, and load it by ExternalObject, but again with no result. It seems environment doesn't know what ExternalObject is.
Is it possible to work with XMP data in extension? If yes, what I need to add/install to make it work?

The XMP data returned by projectItem.getXMPMetadata() contains all marker info for that project item. To confirm this, add some markers containing unique text strings to a clip in Prelude, import it into PPro, then getXMPMetadata() on it; you'll find your text strings in the returned XMP data.
You will need to parse the XMP on your own (or using an XML parser of your choosing), to extract that project item's marker data.
We have a feature request for "XMPScript support in PPro's ExtendScript engine"; I'll add your name to the list.
Feel free to contact me directly regarding any PPro integration development;

Can't parse XMP metadata from files

Hello,
I am currently having troubles reading custom metadata from a file.
I wrote a really simple test case to show you that, maybe I'm doing something wrong...
Writing a simple property :
static const char * kNS1 = "ns:test1/";
void Foo::writeSimple()
 if( !SXMPMeta::Initialize() )
 LOGIT( LOG_ERROR, "Could not initialize XMP toolkit!" );
 return;
 // custom schema
 std::string actualPrefix;
 bool ret = SXMPMeta::RegisterNamespace( kNS1, "ns1", &actualPrefix );
 XMP_OptionBits options = 0;
 // Must initialize SXMPFiles before we use it
 if ( !SXMPFiles::Initialize( options ) )
 LOGIT( LOG_ERROR, "Could not initialize SXMPFiles!");
 return;
 try
 SXMPMeta meta;
 std::string value;
 meta.SetProperty( kNS1, "name", "value" );
 // just to check the property gets actuelly written in meta
 bool exists = meta.GetProperty( kNS1, "name", &value, 0 );
 std::cout << "writeRead: " << value << std::endl; // output is ok
 // Options to open the file with - open for editing and use a smart handler
 XMP_OptionBits opts = kXMPFiles_OpenForUpdate | kXMPFiles_OpenUseSmartHandler;
 std::string status = "";
 // First we try and open the file
 bool ok = p_private->m_file.OpenFile( "Collines.jpg", kXMP_UnknownFile, opts );
 // Check we can put the XMP packet back into the file
 if( p_private->m_file.CanPutXMP( meta ) )
 // If so then update the file with the modified XMP
 p_private->m_file.PutXMP( meta );
 else
 LOGIT( LOG_ERROR, "PutXMP: cannot put XMP" );
 p_private->m_file.CloseFile();
 SXMPFiles::Terminate();
 SXMPMeta::Terminate();
 catch( XMP_Error& e )
 LOGIT( LOG_EXCEPTION, "writeSimple: " + std::string(e.GetErrMsg()) );
Reading the property:
void Foo::readSimple()
 if( !SXMPMeta::Initialize() )
 LOGIT( LOG_ERROR, "Could not initialize XMP toolkit!" );
 return;
 // custom schema
 std::string actualPrefix;
 bool ret = SXMPMeta::RegisterNamespace( kNS1, "ns1", &actualPrefix );
 XMP_OptionBits options = 0;
 // Must initialize SXMPFiles before we use it
 if ( !SXMPFiles::Initialize( options ) )
 LOGIT( LOG_ERROR, "Could not initialize SXMPFiles!");
 return;
 try
 // Options to open the file with - open for editing and use a smart handler
 XMP_OptionBits opts = kXMPFiles_OpenForUpdate | kXMPFiles_OpenUseSmartHandler;
 std::string status = "";
 // First we try and open the file
 bool ok = p_private->m_file.OpenFile( "Collines.jpg", kXMP_UnknownFile, opts );
 // Check we can put the XMP packet back into the file
 SXMPMeta meta;
 std::string xmpPacket;
 XMP_PacketInfo packetInfo;
 ok = p_private->m_file.GetXMP( &meta, &xmpPacket, &packetInfo );
 std::cout << "DBG: getXMP: " << xmpPacket << std::endl; // output is ok, I can see what I wrote before
 std::string value;
 bool exists = meta.GetProperty( kNS1, "name", &value, 0 ); // returns false...
 std::cout << "writeRead: " << value << std::endl; // nothing in value
 p_private->m_file.CloseFile();
 SXMPFiles::Terminate();
 SXMPMeta::Terminate();
 catch( XMP_Error& e )
 LOGIT( LOG_EXCEPTION, "readSimple: " + std::string(e.GetErrMsg()) );
Do you have any idea?
Thanks in adavance!

Hello? No one has any idea?

Incrementally appending custom XMP metadata into PDF files

I have a problem writing custom XMP metadata into a PDF document (I'm using the XMP Toolkit SDK).
The problem is that I don't know whether is possible to expand the XMP packet in order to append metadata incrementally into the document, and, if it is possible, I don't know how to do it. The program I wrote succesfully appends an item to an array four times, but it fails when trying to append the fifth one. The reason obviously is that the packet gets full and there is not room for more metadata. The error message, if I force the PutXMP call, is:
ERROR: Can't fit into specified packet size
So, what can I do? How to enlarge the packet or make it expandable? Or, otherwise, have I to inject a new XMP packet with the up-to-date information in it? How?
And a last question: Have I to scan for packets when dealing with PDF files? No smart handlers are available for this kind of files?
Thanks in advance.

Read metadata from PDF via VBA

I wrote a VBA script that reads the custom properties of a collection of Word docs and writes the results to a file which I can then import to Excel.
Now I have to do the same thing for the PDF files created from the Word docs - that is, read the metadata from a collection of PDF files.
The fields that have to be read are always the same.
How can I read the metadata of a CLOSED PDF file from VBA?
For Word, the solution was to use DSOleFile.PropertyReader (part of the DS: OLE Document Properties 1.4 object library.
TIA

I refer you to some of the vendors that I just posted - perhaps there is a low cost solution you can find. Pound Hill has some scripting interfaces that might help.
Otherwise you will need to take the free SDK and hook it up somehow.

XMP metadata from Flashbuilder why not visible in Adobe Bridge?

Hi there,
I'm currently wondering around XMP metadata and swf files.
A: Flash CS5: works
When I use the XMP panel in Flash CS5 and export a swf, open Adobe Bridge CS5 and select the file, the XMP data are correctly displayed.
B: Flash Builder(Flex 4.1): don't work
When I use Flashbuilder and add my metadata to the compilation, then compile, open Adobe Bridge CS5 and select the file, nothing is included in metadata.
Procedure based on the following (same problem if metadata are directly set through compiler arguments):
http://livedocs.adobe.com/flex/3/html/help.html?content=compilers_14.html
../src/config/ProductMetaData.xml
<flex-config>
<metadata>
 <title>My title</title>
 <description>My description</description>
 <publisher>The publisher</publisher>
 <creator>The creator</creator>
 <language>EN</language>
</metadata>
</flex-config>
compiler argument
-load-config+=config/ProductMetaData.xml
As far as understood, on the background the following is added to the swf at compile time:
<rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'>
 <rdf:Description rdf:about='' xmlns:dc='http://purl.org/dc/elements/1.1'>
 <dc:format>application/x-shockwave-flash</dc:format>
 <dc:title>My title</dc:title>
 <dc:description>
 <rdf:Alt>
 <rdf:li xml:lang='x-default'>My description</rdf:li>
 </rdf:Alt>
 </dc:description>
 <dc:publisher>The publisher</dc:publisher>
 <dc:creator>The creator</dc:creator>
 <dc:language>EN</dc:language>
 </rdf:Description>
</rdf:RDF>
I've checked that the medata is correctly added to the swf file using this small software polarswf:
http://download.cnet.com/Polar-SWF-MetaData/3000-6676_4-10738623.html
I do not know if it is safe to use it in a produciton context at least in trial mode it allows to check the metadata included in your swf.
I wonder if this metadata coonot be read by Adobe Bridge because they are at a "lower level" than those put by flash CS5 XMP panel?
Thank you in advance for your help.
This is not a blocking situation, but I'm curious to understand what happend.
Cedric Madelaine (aka maddec)

I was following this post for a LONG time, since I noticed the same problem.
This week I was getting in it into myself again and I noticed you use load-config. I used these compiler options :
contributor name
Sets metadata in the resulting SWF file. For more information, see Adding metadata to SWF files.
creator name
Sets metadata in the resulting SWF file. For more information, see Adding metadata to SWF files.
date text
Sets metadata in the resulting SWF file. For more information, see Adding metadata to SWF files.
But that resulted in this XML string where the dc namespace was missing a / on the end of the URI
That caused the metadata which was added in flashbuilder was only visible in bridge in the rawXML panel, and not the specific fields
changing the URI in http://purl.org/dc/elements/1.1/ did the trick ( did this in bridge by exporting the rawXML, changed the / , and imported it )
<rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'>
 <rdf:Description rdf:about='' xmlns:dc='http://purl.org/dc/elements/1.1'>
 <dc:format>application/x-shockwave-flash</dc:format>
 </rdf:Description>
</rdf:RDF>
Sadly there was no way I could add this / myself everytime.
BUT then I discoverd this option :
raw-metadata XML_string
Defines the metadata for the resulting SWF file. The value of this option overrides any metadata.* compiler options (such as contributor,creator, date, and description).
This is an advanced option.
And you could give the exact RAW XML as you described
<rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'>
 <rdf:Description rdf:about='' xmlns:dc='http://purl.org/dc/elements/1.1/'>
 <dc:format>application/x-shockwave-flash</dc:format>
 <dc:title>My title</dc:title>
 <dc:description>
 <rdf:Alt>
 <rdf:li xml:lang='x-default'>My description</rdf:li>
 </rdf:Alt>
 </dc:description>
 <dc:publisher>The publisher</dc:publisher>
 <dc:creator>The creator</dc:creator>
 <dc:language>EN</dc:language>
 </rdf:Description>
</rdf:RDF>
to the compiler. This could also be done in Flash with JSFL.
In the end I wrote an ANT script which injects the exact XMLstring of metadata to Flash and Flex projects by using the raw-metadata parameter in FLEX and JSFL for flash.
Hope this helps

Modify LabelGraphics.js to extract other XMP metadata from images

This script works flawlessly. However, I would like to be able to extract other XMP metadata than just
//XMP description
 case 2:
 try{
 myLabel = myLink.linkXmp.description;
 catch(myError){
 myLabel = "No description available.";
 break;
 //XMP author
 case 3:
 try{
 myLabel = myLink.linkXmp.author
 catch(myError){
 myLabel = "No author available.";
I have developed a custom info panel (based on the generic one) with following "properties.xml":
<xmp_definitions xmlns:ui="http://ns.adobe.com/xmp/fileinfo/ui/">

 <ui:separator/>
 </xmp_schema>
</xmp_definitions>
Now I would like to adapt the LabelGraphics.js to retrieve the information stored in the fields "Titel_FR", "Tekst_FR", "Titel_VL", "Tekst_VL", "Titel_NL", Text_NL". These fields contain fixed text that goes with the image and should be retrieved in several "goes".
Question 1: is this possible at all ?
Question 2: how to proceed ?

Extract Metadata from PDF as xmp file

Hello!
I have the following problem: I do always File->properties->additional metadata->advanced-> save as .xmp. How could I write this actions in Javascript?

Thank you for your reply. Unfortunatelly I know javascript badly. I have found the code that creates metadata and open it as pdf (but i need xmp):
var r = new Report();
r.writeText(this.metadata);
r.open("myMetadataReportFile");
I also found the code that must create new next file, but it doesn't work:
var filePath = 'C:/Temp/filename.txt';
var fileSysObj = new ActiveXObject('Scripting.FileSystemObject');
fileSysObj.CreateTextFile(filePath);
Habe you any ideas how to combine these codes to solve my problem? (I know javascript badly and can#t do it)
Thank you for your hepl!

Can't write large xmp metadata to pdf

Hello,
I tried to add a custom metadata of 2kb to the pdf, using PutXmp() method.The API supports "inplace" serialization of exact size - it serializes my packet to the size of the old xmp packet. If my packet size is small - it succeeds; otherwise, like in case of 2kb - fails.Moreover, if there is no old xmp packet, it can't put my xmp. Are there any limitations?I tried to remove some flags in API and PutXmp() performed "not inplace" serialization - that way it succeeded to serialize a big packet.Then I call CloseFile() method which performs an actual writing to file. When I open a pdf in txt format, I see the meta is writen correctly in a correctplace. But when I open the pdf file, the "out of memory" message is displayed.When I try to close the pdf file, it asks if I want to save it. Please advise how to add a large amount of metadata without getting the pdf corrupted.

Hi Curt,
Thanks for your response.
No, there is currently no metadata displayed for the WAV file. I was getting the impression from forums that WAV files can't carry metadata but I thought Bridge would create a sidecar file to carry it.
Cheers,
Josh
