Hi Richard, > Essentially it means that D2R Server makes the URIs of classes and properties in the vocab: namespace (which is used in auto-generated mapping files, and which is defined relative to the server's > base URI) resolvable. Making class and property URIs resolvable is considered good practice in the linked data world.
Therefore, if I use my own classes and properties, I need to publish the RDF that describes them in a way that it's "resolvable" (like in a Joseki server). D2R-Server won't serve this RDF, only what's inferrable by the mappings. Did I got it now? =) thanks! Diogo F.C. Patrão Manager of Medical Informatics Biotechnology Laboratory Hospital A.C.

------------------------------------------------------------------------------ Gaining the trust of online customers is vital for the success of any company that requires sensitive data to be transmitted over the Web. Learn how to best implement a security strategy that keeps consumers' information secure and instills the confidence they need to proceed with transactions. http://p.sf.net/sfu/oracle-sfdevnl
