    212212=== I have database in RMDB, how can I convert them directly to RDF? ===

    214 Possibly using a protege plug-in (which on?) or by providing a web service. There is [http://www4.wiwiss.fu-berlin.de/bizer/d2rq/ D2RQ] which works okey but lacks a bit performance-wise. However, this really depends on whether or not you intend to publish your database as a SPARQL endpoint.  The poll that Pierre Lindenbaum and Mark Wilkinson took over the past couple of days suggests that only 5 data providers (within Tweet-shot of us) currently provide SQL access to their data resources.  This does not seem to bode well for having data providers set-up SPARQL endpoints:  why would they open themselves to a new, unfamiliar technology when they don't open themselves to a well-known, tested, secure, and highly powerful technology?

    216216Mark Wilkinson's team have tried to make a compelling argument that exposing resources via SADI Web Services gives you the best of both worlds - a highly-granular control over what data you expose, how you expose it, and over the distribution of large numbers of requests over your compute-resources; yet the SHARE client helps make it *appear* that the entire world is one big SPARQL endpoint (on steroids, since you can SPARQL data that doesn't even exist until you ask the question!)
