Representations of basic relations in the DataSources ontology in the Protégé editor a) Topic Biology b) Subtopic BiologyTarget c) Template “Found targets for the drug” and some of its properties d) PIBAS/CPCTAS dataset instance. This figure shows screenshots of the local ontology DataSources in the Protégé ontology editor [50]. The ontology contains information about initiatives and datasets included in predefined Federated SPARQL queries. Each dataset in the ontology is represented as an instance of a certain class. The object property conectedWith connects dataset instances with template instances. Every Subtopic class instance is connected with a Template class instance through the object property hasTemplate. Every Topic class instance is connected with a Subtopic class instance through the object property hasSubTopic
