CHAPTER 10: Scripting Access to XMP Metadata Accessing the XMP scripting API 260

Integrating XMPScript with Adobe Bridge

This script adds a command to the context menu for Thumbnails that shows some of the XMP properties.

It demonstrates how to retrieve the XMP metadata that is stored with the Thumbnail object, and use it to

create an XMPMeta object

, then use that object to retrieve different types of property values.

To use this script, place it in the “Startup Scripts” folder for Adobe Bridge (see “

Startup scripts” on page 12).

When you start Adobe Bridge, select a thumbnail for a document that contains XMP metadata, right click,

and choose Show XMP Properties from the menu.

$.writeln("XMPFiles batch processing example");

// define folder containing images (make sure that you use copies)

var picFolder = "/c/temp/photos";

// load the XMPScript library

$.writeln("XMPScript Adobe Bridge Integration Example");

// load the XMPScript library

if (ExternalObject.AdobeXMPScript == undefined){

ExternalObject.AdobeXMPScript = new

ExternalObject(’lib:AdobeXMPScript’);

}

// add a context menu item to Thumbnails

var xmpCommand = new MenuElement("command", "Show XMP Properties",

"at the end of Thumbnail", "showProperties");

// define command behavior

xmpCommand.onSelect = function(m) {

// get the first selected thumbnail

thumb = app.document.selections[0];

// if there is one, and it has metadata

if (thumb && thumb.metadata) {

// retrieve metadata from the thumbnail into an XMPMeta object

// (if app.synchronousMode is set, use thumb.metadata)

xmp = new XMPMeta(thumb.synchronousMetadata.serialize());

// retrieve some of the XMP property values

// a simple property with a localized string value

var msg = "Title: " + xmp.getLocalizedText(XMPConst.NS_DC,

"title", null, "en") + "\n";

// an array property

msg += "Authors of the document:\n";

num = xmp.countArrayItems(XMPConst.NS_DC, "creator");

for (i = 1; i <= num; i++)

msg += "* " + xmp.getArrayItem(XMPConst.NS_DC,

"creator", i) + "\n";

// a simple property with a date value

msg += "Creation Date: " + xmp.getProperty(XMPConst.NS_XMP,

"CreateDate")

// display the values

Window.alert(msg);

}

else

Window.alert("No thumbnail selected or no XMP contained");

};
