=== Overview === #overview


Query of RDF data via SPARQL endpoints can be processed based on the original date sources.  We evaluate federated SPARQL endpoint query systems for real life sciences data. Different from Fedbench,SP2Bench, and the fine-grained evaluation of SPARQL endpoint federation systems, all of which use a simulated federated environment, and synthetic data or subset of real data. We use the real life science data and the real endpoints. We test FedX,SPLEND,ADERIS,GDS.
