The BioGateway graphs architecture. Four frameworks (A-D) are implemented within BioGateway. All of them are interlinked via a common set of relations and share the same namespace: SSB. In A, all the ontologies (O _i ) are integrated into one single graph named SSB. In B, each ontology (O _i ) has its own single graph named O _i . In C, all the transitive closure ontologies (O_i,tc) belong to one single graph named SSB_tc. In D, each transitive closure ontology (O_i,tc) has its own single graph named O_i,tc.
