Another thing of note here are the different databases RDF traditionally uses. Take a look at: https://github.com/openlink/virtuoso-opensource https://github.

Another thing of note here are the different databases RDF traditionally uses. Take a look at: https://github.com/openlink/virtuoso-opensource https://github.com/openlink/virtuoso-opensource This is the triples store traditionally used. You will also want to look in to sparql. An example link: http://www.ibm.com/developerworks/xml/library/j-sparql/ http://www.ibm.com/developerworks/xml/library/j-sparql/ The syntax is a bit weird, but it's not that different from a document store. For those of you who use the Facebook API, you can also get RDF data out with the rdf Accept header. Something neat to think about.
