Welcome to TuQS! Turnguard's QuadStore is the first draft of an own implementation of a QuadStore with main focus on data-retrieval speed. TuQS can be queried and updated using openrdf's SAIL API. Please choose a repository here. * Features o SAIL accessible o True QuadStore with GraphSupport o HighSpeed regex SPARQL filters o Userrights on TripleBasis o Extendable to a QuintStore (or more generally to an n-Store) o Cachable SPARQL Queries for further speed improvement o Clusterable o Federationable o FullTextSearchable
