Accessing XMP Metadata Using Acrobat JavaScript

The metadata
metadata embedded in a PDF document. The method returns a string containing the XML
text stored as metadata in a particular PDF document.

Accessing XMP Metadata From a Plug-in

You can access XMP metadata information using the Acrobat SDK. Plug-ins can get or set
XMP metadata using the
PDDocSetXAPMetadataProperty
properties in a pdDoc's Info dictionary, as well as properties that are not in the Info
dictionary.

You can also get or set the XMP metadata associated with a Cos dictionary or stream, or
with a PDEContainer. These APIs are all included in the
See the Acrobat API and PDF Library API Reference for more information on these APIs.

Acrobat Distiller and XMP Metadata

Acrobat Distiller supports embedding of XMP metadata in PDF files in two ways.
First, it always generates document level metadata. This metadata is derived from the
PostScript file and cannot be modified by the PostScript program. To change the document
level metadata, you must change it in the authoring application that generates the
PostScript stream.
A second way of adding metadata is to create object data. See
for more information.

The Adobe XMP Toolkit

The XMP Toolkit is designed to help applications handle XMP operations such as the
creation and manipulation of metadata. The Toolkit makes it easier for developers to
support XMP metadata, and helps to standardize how the data is represented and
interchanged. The XMP Toolkit can be licensed, royalty-free, from Adobe Systems.
The XMP Toolkit features a C++ interface which uses some modern (ANSI) features, such as
exceptions, STL strings, and bool. It uses conservative coding and interface design for
maximum portability and to make it easier for developers to adopt.
