sorry, I used the wrong link for aperture framework in the previous email,
this is the correct one:
http://aperture.sourceforge.net/
(bad copy+paste from the google search to find again the correct url :-))
I suppose the project is no longer mantained, and it probably used PDFBox
as well...
I made a little example PDF based on the example at http://5stardata.info/
where document metadata is in the XMP itself, but document data is just a
string value (this example uses JSON).
The same data from http://5stardata.info/gtd-5.html should be available in the

Hey all,
I think APIs for common languages like Java and C# to extract XMP RDF
from PDF Files/Streams would be much more helpful than standalone
tools such as Paul mentions.
I've looked at Adobe PDF Library SDK but none of the features mention metadata:
Tim,
I think I ran across a couple of papers about this. Maybe this was it?
Basically, semantics actually help DHT as they are kind of naiive. Hoping
to get back to this.

Selected Areas in Communication, Vol. 25, No. 1,
Concept came from HTTPA.
I posted about it quickly here [1]. Wiki has a short entry about it here
[2] also.
Perhaps the other means would be to use sparql end-points. Quick search
yielded [3]
Another concept for RWW is the capacity to build your own ontologies.

Hi
from PDFbox there are indeed chances to extract metadata (if I'm not wrong
the API are the same used inside Tika [1], which is largely adopted for
indexing out of the box, for example in the Solr context).
Metadata are simple name/value pairs in this context, but it's simple to
map them

How about HTTP Link headers (RFC 5988) to convey links and metadata expressed
as links when serving PDFs? I can imagine an authoring tool embedding the info
in XMP. But I have a harder time imagining a consumer application that would
want to read the info via XMP.
How about a web
PDFBox includes metadata API, but does not mention RDF:

Larry,
IMO mixing RDF/XML with JSON doesn't make sense. Why not keep it
RDF/XML? Like this (not tested):
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:pdf=http://ns.adobe.com/pdf/1.3/;

I just used Acrobat Pro to look at the XMP metadata for a standards

in this particular case this is fine RDF, just very little of it because
