We announce that Carlos Buil, member of the OEG, has developed the SPARQL-DQP system. This system implements the SPARQL 1.1 Federated Query extension, by extending the OGSA-DAI/DQP system. The optimisation of these federated queries is done in SPARQL-DQP by identifying well-designed patterns in queries. Using such patterns it is possible to apply rewriting rules to federated SPARQL queries and improve the execution time of the queries.

The code and an online demo will be soon available.
