Question

Indesign script – get xmp metadata for broken links

Hi All,

often I have to work with indesign documents at different locations and I have to deal with broken links.

My main problem is to get the credit-lines for missing images (usually JPeG-previews from adobe.stock.com) with a script. These are stored in the indd-file, even if the image-file is missing. See Example 2 below.

Is there a way to get this information by java script? Up to now I only could mange to
get these information for existing files with the code below (Example 1).

Can anyone help, please?

Thanks Thomas

Example 1 – my code to read xmp-info for existing files:

if (ExternalObject.AdobeXMPScript == undefined){

ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript'); }

//read Photoshop entry:

var xmpFile = new XMPFile (fileRef.fsName, XMPConst.NS_PHOTOSHOP, XMPConst.OPEN_FOR_READ);

var xmp = xmpFile.getXMP();

xmpFile.closeFile()

var myPS_Credit = xmp.getProperty(XMPConst.NS_PHOTOSHOP,"Credit");

Example 2 – xmp-data for missing image taken from indd-file displayed with "less-command":

Sorry, but I'm sick and tired of fighting with this lousy new forum software.

I really don’t understand why Adobe decided to ruin something that worked well for years.

Who knows what [removed] is this? Why I can’t just post a reply?

Well, I had to reset my password today ...

I don´t know what´s going on.

Anyway, I´ll do some tests tonight. I found this, possibly it is a question of different namespaces?

NS_XMP_MM The XML namespace for the XMP digital asset management schema.

NS_XMP_BJ The XML namespace for the job management schema.

NS_XMP_NOTE The XML namespace for the XMP note schema. An Adobe private namespace; do not create new properties.

NS_PDF The XML namespace for the PDF schema.

NS_PDFX The XML namespace for the PDFX schema. An Adobe private namespace; do not create new properties.

NS_PHOTOSHOP The XML namespace for the Adobe Photoshop custom schema.

It seems to me that both should work identically, but it doesn't:

Theoratically, this should work:

main();

function main() {
	var doc = app.activeDocument;
	var link = doc.allGraphics[0].itemLink;
	var xmp = link.linkXmp;
	var prop = xmp.getProperty(XMPConst.NS_PHOTOSHOP, "photoshop:Credit");
	$.writeln((prop == "") ? "FAILED" : prop);
}

But in practice it doesn't, though it works, for some reason with, say, XResolution (also with a missing file)

main();

function main() {
	var doc = app.activeDocument;
	var link = doc.allGraphics[0].itemLink;
	var xmp = link.linkXmp;
	var prop = xmp.getProperty(XMPConst.NS_TIFF, "tiff:XResolution");	
	$.writeln((prop == "") ? "FAILED" : prop);
}

I don't understand why one works but another doesn't.

I just made a quick test and, yes, it's possible. For example, let's try this code:

main();

function main() {
	var doc = app.activeDocument;
	var link = doc.allGraphics[0].itemLink;
	var xmp = link.linkXmp;
	var author = xmp.author;
	var propCredit = xmp.getProperty(XMPConst.NS_PHOTOSHOP, "Credit");
}

It works with a missing link as well.

Hi Kasyan,

Unfortunately your code does not work with preview-images downloaded from stock.adobe.com
The file-information that you request in your code returns an empty string. I think this is because the file-information is empty (see image).

It is not a problem to access author and credit information for missing files that I created myself, but it seems to be a little tricky with adobe-stock-previews.

It seems to me, that I need access to the raw-xmp-data (see image 2) ... but I dont know how.

Best, Thomas

BTW: I tested this with Indesign CC 2019/2020 German version
