Hi

I am working with a client that has a requirement to store document oriented content but with the need to run complex join queries across the data.

Queries will not be known before hand and would ideally be able to incorporate other linked data.

Above and beyond this they would like to run reasoners over the data.

For querying and flexibility in using third party reasoners providing a SPARQL endpoint looks like a feature any solution would need.

I have seen there is a MongoGraph integration from AllegroGraph for MongoDB that provides a SPARQL endpoint over the document database.

It would be great if this kind of integration was available for Couchbase, is there anything likely to be available in the immediate to near term?

TIA

Andy

Hello march44

At the moment we have no near term / intermediate term plans to add support for SPARQL end points. Along with supporting the language (parser, compiler etc), to support SPARQL the database also needs to be aware of triples (RDF). This implies server side changes as well which can be a substantial effort.

FWIK, Mongograph actually is a wrapper used on top of AllegroGraph. The data is stored as triples in AllegroGraph but can be queried using the MongoDB API.

Are you looking for support for SPARQL or support for a Couchbase API (example: GET / SET) for AllegroGraph?

Hi, thanks for the reply.

I'm looking to use couchbase server as a an efficient scalable RDF triple store.

The SPARQL query engine would sit over the couch base cluster.
