- ANAPSID: An Adaptive Query Processing Engine for SPARQL Endpoints + (Lightweight wrappers translate SPARQL sub- … Lightweight wrappers translate SPARQL sub-queries into calls to endpoints as well as convert endpoint answers into ANAPSID internal structures. Mediators maintain information about endpoint capabilities, statistics that describe their content and performance, and the ontology used to describe the data accessible through the endpoint. The Local As View (LAV) approach is used to describe endpoints in terms of the ontology used in the endpoint dataset. Further, mediators implement query rewriting techniques, decompose queries into sub-queries against the endpoints, and gather data retrieved from the contacted endpoints. Currently, only SPARQL queries comprised of joins are considered; however, the rewriting techniques have been extended to consider all SPARQL operators, but this piece of work is out of the scope of this paper. Finally, mediators hide delays, and produce answers as quickly as data arrives.roduce answers as quickly as data arrives.)
