RDF/OWL/Sparql and native XML databases

Hi all,

 

Admittedly, this is not a semantic-web question, per se, but I'm
thinking that this list may be more relevant than xml-dev...but I could
be wrong.

 

Does anyone have any experience or comments on using a native XML
database (e.g. MarkLogic, Exist, Oracle XML DB) as a triple store?  If
so, I'm curious as to how the translation from a XML model to the RDF
model can be achieved.  From my experience, most of these products focus
on XQuery (which is great but doesn't seem powerful enough to understand
the RDF model except to possibly extract all rdf:Description elements
and then pass them off to something like Jena separately) and I'm also
not aware of any means for connecting to native XML databases via Jena
or other RDF (or OWL) enabled processors.  It seems that XQJ may
eventually provide a standard for connectivity (that could be built on
top of) but I don't think it is widely implemented yet.  Does anyone
have enough exposure to this area to either confirm (or contradict)
these statements.  The ability to use a native XML database for both
"content" (books, etc.) in addition to RDF metadata seems compelling but
I'm not sure if it has been done or is even currently doable.  Thanks in
advance!
