Retrieves or replaces existing metadata
in the PDF document. The metadata is specified as XML source in
EXtensible Metadata Platform (XMP) format or as a reusable PDF document.
XMP provides a standard format for creating, processing, and
interchanging metadata for a wide variety of applications. XMP uses
the W3C standard Resource Description Framework (RDF).
In XMP, metadata consists of a set of properties that are associated
with a document. Metadata includes the properties author, creator,
keywords, producer, subject, and title of a PDF document. In a PDF
document, metadata can be stored in two places:
The file trailer dictionary of text, not in XML format
using a XMPUtilityMetadata (com.adobe.livecyclSe.xmputility.client.XMPUtilityMetadata)
value.
In the Metadata dictionary of the document catalog. This
dictionary contains metadata associated with the entire document.
This information is represented in XMP format which can be saved
to file.
For information about using the XMP Utilities service, see Services Reference for Adobe LiveCycle ES4.
