Appending metadata to a file

[europeanrich]

Hi,

I found this script to write XMP metadata to an open file, but it does not seem to work for me in Illustrator CC. The error message is "XMP exception: Source and destination XMP must differ".

Is there perhaps an alternative method of writing properties to the XMP fields?

Thanks,

Rich

if( xmpLib == undefined ) {

var xmpLib = new ExternalObject("lib:../../Frameworks/AdobeXMPScript");

app.synchronousMode = true;

}

var docXmp = new XMPMeta(app.activeDocument.XMPString);

var myXmp = docXmp;

myXmp.setProperty(XMPConst.NS_XMP, "CreatorTool", "My Script");

XMPUtils.appendProperties(myXmp, docXmp, XMPConst.APPEND_ALL_PROPERTIES);

var myDocFile = new File(app.activeDocument.fullName);

var docRef = new XMPFile(myDocFile.fsName, XMPConst.FILE_UNKNOWN, XMPConst.OPEN_FOR_UPDATE);

if (docRef.canPutXMP(docXmp)) { docRef.putXMP(docXmp); }

docRef.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);

Is that all your script or just part of it…? Either way it's got a line that is Bridge script…

app.synchronousMode = true; // This ONLY applies to the Bridge App…

It's just part of the script. I want to test if I can write metadata information to the illustrator file. I can then go on target specific fields.

I've removed the Bridge script line, but it's still showing the same error.

After much searching I discovered another script that does the trick. The document must be closed and then reopened to view the modifications (took me a while to realise this!)

// load XMP Library

function loadXMPLibrary(){

    if ( !ExternalObject.AdobeXMPScript ){

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

        catch (e){alert('Unable to load the AdobeXMPScript library!'); return false;}

    }

    return true;

}

// select destination file

var myFile = File.openDialog("Select destination file", "Illustrator:*.ai", false);

// check library and file

if(loadXMPLibrary() && myFile != null){

    xmpFile = new XMPFile(myFile.fsName, XMPConst.FILE_UNKNOWN, XMPConst.OPEN_FOR_UPDATE);

    var myXmp = xmpFile.getXMP();

}

if(myXmp){

    // change Document title to Foo

    myXmp.setProperty(XMPConst.NS_DC, "title", "Foo");

    // put XMP into file

    if (xmpFile.canPutXMP(myXmp)){xmpFile.putXMP(myXmp);}else{alert("Error storing XMP");}

    // close file

    xmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);

}
