The BioGateway pipeline. Information resources are converted to RDF documents which are uploaded to a triple store, where they can be queried using SPARQL: First, the candidate OBO Foundry ontologies, the GOA files, the NCBI taxonomy and SWISS-PROT are integrated within the common framework defined by the in-house ontologies: BioMetarel and Metaonto. Then, for each resource, an RDF graph (and for the OBO foundry its corresponding transitive closure graph) is created and loaded into Virtuoso. This platform provides an interface (via SPARQL) to interrogate the system.
