Retrieving XMP metadata from After Effects Comp

[Kelly Anderson]

Hi,

I've successfully retrieved XMP metadata from a custom Project schema. Like this:

var proj = app.project;

var customMetadataSet = "Starz";

var customMetadataField = "Episode";

if(ExternalObject.AdobeXMPScript == undefined) {

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

}

var metaData = new XMPMeta(proj.xmpPacket);

var schemaNS = XMPMeta.getNamespaceURI(customMetadataSet);

if(schemaNS == "" || schemaNS == undefined) {

    alert("no custom metadata named: " + customMetadataSet);

} else {

    var metaValue = metaData.getProperty(schemaNS, customMetadataField);

    if(!metaValue) {

        alert("no custom field named: " + customMetadataField + " In set: " + customMetadataSet);

    } else {

        alert(customMetadataField+ ": " + metaValue.value);

    }

}

But now I have 2 questions.

1. How do I get Project XMP metadata from Dublin Core or Basic set?
2. How do I get XMP metadata from a selected Comp and the Dynamic Media set?

Thanks for any insight.

Here is a sample script that can retrieve dc:fomat data. It may help you.

XMPBasic = {
  ns : "http://purl.org/dc/elements/1.1/",
  prefix : "dc",
  read : function(){
  if(xmpLib==undefined) var xmpLib = new ExternalObject('lib:AdobeXMPScript');
  var tgt = File.openDialog("Select source file", undefined, false);
  var xmpFile = new XMPFile(tgt.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ);
  var xmpPackets = xmpFile.getXMP();
  var xmp = new XMPMeta(xmpPackets.serialize());
  alert(xmp.getProperty(this.ns, "format").toString());
  },
  write : function(f, val1, val2){ //f:fileObject, val1:String, val2:String
  if(xmpLib==undefined) var xmpLib = new ExternalObject('lib:AdobeXMPScript');
  var xmpFile = new XMPFile(f.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_UPDATE);
  var xmp = xmpFile.getXMP();
  var mt = new XMPMeta(xmp.serialize());
  XMPMeta.registerNamespace(this.ns, this.prefix);
  mt.setProperty(this.ns, "value1", val1);
  mt.setProperty(this.ns, "value2", val2);
  if (xmpFile.canPutXMP(xmp)) xmpFile.putXMP(mt);
  xmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);
  }
  }
//XMPBasic.write(File.openDialog(), "1", "2");
XMPBasic.read();
