Yes TDB provides full SPARQL 1.1 support ARQ is the query engine which is fully SPARQL 1.1 compliant
TDB is a persistence layer, it uses the ARQ query engine to perform the actual queries (though it extends the basic ARQ engine with some TDB specific optimisations to improve performance) Rob On 10/03/2015 07:16, "Rose Beck" <[email protected]> wrote: >Ok actually I want to run SPARQL 1.1 queries and I want a persistent >on-disk database for it which ARQ does not provide.
