Rdf query on cassandra (ruby) #2

Open nolamesa opened 14 years ago

nolamesa commented 14 years ago

I am a thinking to set up a cassandra db and use it with the adapter rdf-cassandra for saving rdf triples. From the documentation i found i cannot see how i can query cassandra. I think i will be able to do basic triple search but not a sparql query. Is there a way to get a sparql endpoint? ( i think i read someone was using sesame for querying cassandra!?) Any suggestions...? Is there a way to use sparql-client along with cassandra db?

At present it's not yet possible to query RDF::Cassandra with SPARQL, but there is ongoing work to eventually make this possible by plugging in ARQ as the SPARQL engine (see the RDF::ARQ project).

However, a lot of work remains to be done both on RDF::Cassandra and RDF::ARQ before a generally-useful release is possible. At the moment, RDF::Cassandra should be considered alpha quality and RDF::ARQ is experimental at best (pre-alpha).
