XMP (''Extensible Metadata Platform'') provides a standard to work with metadata.

This page describes how to declare such metadata in fo file.

/!\ This works only with FOP trunk.

== Properties sets ==
Metadata is made of properties sets.

Properties sets are:
||<:>'''Set'''||<:>'''Namespace'''||<:>'''URI'''||<:>'''FOP support'''||
||Dublin core||dc||http://purl.org/dc/elements/1.1/||Partial||
||XMP basic||xmp||http://ns.adobe.com/xap/1.0/||Partial||
||XMP Rights Management||xmpRights||http://ns.adobe.com/xap/1.0/rights/||None||
||XMP Media Management||xmpMM||http://ns.adobe.com/xap/1.0/mm/||none||

=== Dublin Core set ===
||<:>'''Property'''||<:>'''Comment'''||<:>'''FOP support'''||

== Declaring properties in fo file ==
All metadata properties can be declared in the {{{fo:declarations}}}.

XMP specification recommends to use {{{x:xmpmeta}}}, {{{rdf:RDF}}}, and {{{rdf:Description}}} elements as shown in example below.

Only one of the 2 first is required to make PDF to recognize metadata properties.

=== Example ===
{{{
<fo:declarations>
	<x:xmpmeta xmlns:x="adobe:ns:meta/">
		<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
			<rdf:Description rdf:about=""
				xmlns:dc="http://purl.org/dc/elements/1.1/">
				<!-- Dublin Core properties go here -->
				<dc:title>Document title</dc:title>
				<dc:creator>Document author</dc:creator>
				<dc:subject>Document subject</dc:subject>
			</rdf:Description>
			<rdf:Description rdf:about=""
				xmlns:xmp="http://ns.adobe.com/xap/1.0/">
				<!-- XMP properties go here -->
				<xmp:CreatorTool>Tool used to make the PDF</xmp:CreatorTool>
			</rdf:Description>
		</rdf:RDF>
	</x:xmpmeta>
</fo:declarations>
}}}
<!> {{{fo:declarations}}} __must__ be declared after {{{fo:layout-master-set}}}
