I asked a colleague from HP who works on Jena about this, and here's his
"Jena can be used - I have seen question on the support mailing lists where
people do this. Adobe's XMP format is RDF which Adobe embed in their file
formats like PDF. XMP is actually is a restricted usage of RDF but that
means Jena's compliant parser can parse any RDF and RDQL can query it.
Personally, I don't know how people access the XMP within a file but people
do. Asking questions on [log in to unmask] for other people who
have done this should help.
So - Jena itself does not provide the XMP data extraction in the toolkit.
Jena can parse and handle the XMP RDF once extracted."
By the way, we're building infrastructure here at MIT to deal with RDF in
general (starting with descriptive metadata) with our SIMILE project
http://web.mit.edu/simile/www/ so if you have questions like this about RDF
tools, especially from the W3C or HP, feel free to ask me...
