RDF triplestores and property graph databases are two approaches for data management whichare based on modeling, storing and querying graph-like data. In spite of such common principle, they presentspecial features that complicate the task of database interoperability. While there exist some methods totransform RDF graphs into property graphs, and vice versa, they lack compatibility and a solid formalfoundation. This paper presents three direct mappings (schema-dependent and schema-independent) fortransforming an RDF database into a property graph database, including data and schema. We show thattwo of the proposed mappings satisfy the properties of semantics preservation and information preservation.The existence of both mappings allows us to conclude that the property graph data model subsumes theinformation capacity of the RDF data model.
