documentID to source?

[justmike65]

I tried to modify a script to copy the <xmpMM:DocumentID> to the <photoshop:TransmissionReference>, obviously I have had no luck. Where do I find the correct syntax for calling up the two fields?

	#target bridge
	if( BridgeTalk.appName == "bridge" ) {
	DocumentIDToSource= MenuElement.create("command", "Document ID to Source", "at the end of Tools");
	}
	DocumentIDToSource.onSelect = function () {
	var sels = app.document.selections;
	for(var a in sels){
	md =sels.synchronousMetadata;
	md.namespace = "http://ns.adobe.com/photoshop/1.0/";
	var DocumentID =  md.DocumentID.toString().replace(/,/g,'.');// Replace a comma with decimal point
	md.namespace = "http://purl.org/dc/elements/1.1/";
	md.TransmissionReference='';
	md.TransmissionReference = DocumentID;
	}
	};

Any suggestions will be appreciated.

I do know the purl namespace will have to be changed to something else—I left it there as a placeholder for when I have the right information...

[I have gone]

To find the information for the different fields look at the Raw Data in the files File Info.

As an example:

	xmlns:photoshop="http://ns.adobe.com/photoshop/1.0/">
	<photoshop:ColorMode>3</photoshop:ColorMode>
	<photoshop:ICCProfile>sRGB IEC61966-2.1</photoshop:ICCProfile>
	<photoshop:TransmissionReference>xmp.did:B68E7606EB18E5119A83DC86D4E48975</photoshop:TransmissionReference>
	</rdf:Description>
	<rdf:Description rdf:about=""
	xmlns:xmpMM="http://ns.adobe.com/xap/1.0/mm/"
	xmlns:stEvt="http://ns.adobe.com/xap/1.0/sType/ResourceEvent#">
	<xmpMM:InstanceID>xmp.iid:FADF66149020E511B464E0DEE80B5EE4</xmpMM:InstanceID>
	<xmpMM:DocumentID>xmp.did:B68E7606EB18E5119A83DC86D4E48975</xmpMM:DocumentID>
	<xmpMM:OriginalDocumentID>xmp.did:B68E7606EB18E5119A83DC86D4E48975</xmpMM:OriginalDocumentID>
	<xmpMM:History>

You can see that TransmissionReference is part of the Photoshop namespace and DocumentID is is part of xmpMM namespace

so your code would be.

#target bridge    



    if( BridgeTalk.appName == "bridge" ) {  
    DocumentIDToSource= MenuElement.create("command", "Document ID to Source", "at the end of Tools");
    }
    DocumentIDToSource.onSelect = function () {  
var sels = app.document.selections;
    for(var a in sels){
    md =sels.synchronousMetadata; 




md.namespace = "http://ns.adobe.com/xap/1.0/mm/";



    var DocumentID =  md.DocumentID.toString().replace(/,/g,'.');// Replace a comma with decimal point
    md.namespace = "http://ns.adobe.com/photoshop/1.0/";  
    md.TransmissionReference='';
    md.TransmissionReference = DocumentID;
    }

Thanks! I will try this—I have been away for a long weekend.

You have to modify the namespaces and the exact property names for you purpose, but this can easily be adapted for your purpose:

Hope it helps.

#target bridge
if( BridgeTalk.appName == "bridge" ) {
DocumentIDToSource= MenuElement.create("command", "Document ID to Source", "at the end of Tools");
}
DocumentIDToSource.onSelect = function () {
    loadXMPLib();
    //
    var sels = app.document.selections;
    for(var a in sels){
        if (sels.spec instanceof File && sels.name.match(/\.(cr2|raw|dng|nef)$/i)) {
            var xmp = new XMPMeta(sels.synchronousMetadata.serialize());
            // try another namespace to get other simple properties:
            var DocumentID =  xmp.getProperty("http://ns.adobe.com/xap/1.0/mm/", "DocumentID");
            // If you are getting "localized text properties", use instead this one:
            // var Description =  xmp.getArrayItem("http://purl.org/dc/elements/1.1/", "description",1);
            // settting localized text property
            xmp.setLocalizedText("http://purl.org/dc/elements/1.1/", "TransmissionReference", null, "x-default", DocumentID);
            // setting simple property
            // xmp.setProperty("http://purl.org/dc/elements/1.1/", "NewProp", "my prop value");
            //
            var updatedPacket = xmp.serialize(XMPConst.SERIALIZE_OMIT_PACKET_WRAPPER | XMPConst.SERIALIZE_USE_COMPACT_FORMAT);
            sels.metadata = new Metadata(updatedPacket);
        }
    }
    //
    unloadXMPLib();

              }
