Hello,
i am trying to create a pdf/a with FOP 1.1, but the validation of the
generated PDF always fails due to corrupt xmp-metadata.
I tried several Validators, all of them report the same error:
XMP metadata: Property 'language' in predefined XMP schema
'http://purl.org/dc/elements/1.1/' for PDF/A has wrong value type (must
be 'rdf:bag')
(http://www.pdflib.com/knowledge-base/xmp-metadata/free-xmp-validator/)
So I tried to fix the problem by declaring the language-property in my
fo:declarations-section:
<fo:declarations>
<x:xmpmeta xmlns:x="adobe:ns:meta/"
xmlns:dc="http://purl.org/dc/elements/1.1/";
xmlns:xmp="http://ns.adobe.com/xap/1.0/";
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";>
<dc:creator>
<rdf:Seq>
<rdf:li>
CREATOR
</rdf:li>
</rdf:Seq>
</dc:creator>
<dc:language>
<rdf:Bag>
<rdf:li>
de-DE
</rdf:li>
</rdf:Bag>
</dc:language>
<dc:date>
<rdf:Seq>
<rdf:li>1999-08-01T12:56:02+02:00</rdf:li>
</rdf:Seq>
</dc:date>
<xmp:CreatorTool>My App</xmp:CreatorTool>
</x:xmpmeta>
</fo:declarations>
In the resulting PDF the metadata looks like this:
<?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?><x:xmpmeta
xmlns:x="adobe:ns:meta/">

Is anyone experiencing the same problem? Any tips how to fix this?
Thanks Björn
