Hi David,
Thank you for your reply.
Regarding your assumption on what I meant by "synchronize"... yes you are
completely correct.
{bq}I think this is more a question for Jena Developers{bq}
I had my fears that you would say that ;) however your final comments are both
very helpful and interesting. I did not know about property documents, this
might be a way to at least create *a* link of sorts which is required to
associate the XML doc with its sister RDF.
Thank you
Lewis

data stores
By "synchronize" am I to assume that at some later date you will have new XML
documents and will rerun the XProc pipeline, produce new RDF and store those
into Jena ?
You want to update Jena with the new RDF values AND delete ones that no longer
are present ?
I think this is more a question for Jena Developers ... I would guess you would
want to tag the RDF values somehow so that you knew which ones to replace. I
am not sure how MarkLogic will help (or hinder) this process as everything is
done prior to be put into the ML Database ...
Unless you have a way of also storing the RDF ID's associated with the XML
document. That could possibly be put in a property document of the XML
Document ... but I dont know how you identify RDF triples in Jena.

Subject: [MarkLogic Dev General] Synchronizing content from heterogeneous data
stores
Hi All,
Currently I have a stack of XML documents in MarkLogic. They get there via an
XProc pipeline.
I am currently working to run some custom parsers on the XML (within the
pipeline) *just* before it gets inserted into MarkLogic.
The parsers extract RDF relationships (triples) from the XML content and I
would like to send this extracted structure to a triple store (e.g. Jena TDB).
The idea is then to build my application on top of MarkLogic and use the
triples to compliment structured or text based queries within the search
application.
Currently I would really appreciate some need clarification on one major area
if possible...
How would/could I synchronize the an individual XML document and its associated
triple graph within triple store? This is my major area of confusion. I am
really curious to hear from anyone out there who has attempted anything similar.
Thanks very much for any feedback on this one, I realize it is a pretty lengthy
question but any suggestions would be great.
All the best
Lewis
