Also, I have to note that there is a modification of SPARQL to query quards (we use SPARQL to query data from CP). Suppose, there possible some incompatibility problems between triple- and quard-based CPs.

What about InfoGrid, HyperGraphDB - as I understand, they does not support RDFS/SPARQL. As a result, for these DBs we can implement CP with no query support. > - Higgins XDI endpoint There already exists some (perhaps outdated) IdAS CP implementation used XDI endpoint. > Also if we integrate two or more - would that be like 2-3 weeks each, or some > smaller increment like 1-2 weeks per > additional database provider? Yes, suppose we need to implement base CP with data providers support. Actually, the current Jena CP can be easily refactored in such a way.
