To facilitate access to such databases and to enable data integration of non-relational data sources, we generalize the well-known ontology based data access (OBDA) framework so as to allow for querying arbitrary databases through a mediating ontology. We instantiate this framework to MongoDB, a popular JSON-document database, and implement a prototype extension of the virtual OBDA system Ontop for answering SPARQL queries over MongoDB.
