Hi, > I'm wondering for some time already if there is any triple store > that allows to define custom indexes on special predicates or > subsets of the whole set of triples/quads? All the existing stores I > know index over all triples in different combinations (spo, > pso, ...). Is there any research going on towards partial indexes > over user-defined subsets of triples? E.g. an index over all > xsd:dateTime literals. some time ago I was looking for triple stores that allow to customize the database schema, e.g., that allow me to specify something like "I want all foaf:Person resources together with their foaf:firstName and foaf:surname stored in a designated (optimized) table." If you are aware of any triple store aware of that functionality I would be happy to know. Best, Bernhard
