Edit IPTC metada in illustrator extendscript

[shaig khaligli]

Hi guys,

I'm batch editing all jpeg files metadata. I achieve to edit XMP title,description, keyword of jpeg files. But I want to edit IPTC data of these jpeg files too. Because shutterstock reads metadata from IPTC. So is it possible to edit IPTC description, keyword with extendscript in Illustrator ? if possible how ?

I attached sample jpeg IPTC below. Just I want to copy XMP metadata to suitable IPTC metada.

Any help appreciated ! Thanks !

Here's a function which I dug up from a long time ago which reads only the description string:

function ReadXMPviaLibrary(targetFile){

  if(ExternalObject.AdobeXMPScript == undefined) {

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

  }

  var fNm = targetFile, obj;

  var xmp = new XMPFile( fNm.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ);

  obj = xmp.getXMP();

  xmp.closeFile();

  var descriptionString = "";

  try{

    descriptionString = obj.getLocalizedText(XMPConst.NS_DC, "description", null, "en");

    return descriptionString;

  } catch(e){

    return null;

  }

};

And here's one where Ten_A also adds more code regarding this topic:

Hopefully you can edit the functions to accomplishyour goal!

You can add below method after getXMP() in Silly-V's code. You'll see some IPTC info in ESTK console.

$.write(obj.dumpObject());

Silly-V​ @Ten A,  thank you for your responses. These are so helpful.

But I want to edit IPTC info with ExtendScript. Because shutterstock reads IPTC data, not XMP data. I want to copy XMP to IPTC and save it.

[Silly-V]

As far as I know, It is all inside XMP data. I am wondering if shutterstock is simply reading the IPTC fields inside the XMP data?

Here is a sample dump of metadata.

I used dumpObject just now to get a sense of the way color plate names are recorded inside this data.

Fortunately, it really helped, and extra googling yielded the correct XMPConst enumeration to read this information too:

And now I have a function which gets a file's plates just like this!

function getPlateNamesFromXMP(targetFile){

  if(ExternalObject.AdobeXMPScript == undefined) {

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

  }

  var fNm = targetFile, obj;

  var xmp = new XMPFile( fNm.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ);

  obj = xmp.getXMP();

  xmp.closeFile();

  var metaString = "";

  try{

  var plateNames = [];

    var plateNameAmt = obj.countArrayItems(XMPConst.TYPE_PAGEDFILE, "PlateNames");

    for (var i = 0; i < plateNameAmt; i++) {

    plateNames.push(obj.getArrayItem(XMPConst.TYPE_PAGEDFILE, "PlateNames", (i + 1)));

    }

    return plateNames;

  } catch(e){

    return null;

  }

};
