Directly Mapping RDF Databases to Property Graph Databases
RDF triplestores and property graph databases are two approaches for data
management which are based on modeling, storing, and querying graph-like data.
In spite of such common principles, they present special features that
complicate the task of database interoperability. While there exist some
methods to transform RDF graphs into property graphs, and vice versa, they lack
compatibility and a solid formal foundation. This paper presents three direct
mappings (schema-dependent and schema-independent) for transforming an RDF
database into a property graph database, including data and schema. We show
that two 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 the
information capacity of the RDF data model.Comment: This work has been accepted and published at the IEEE Access Journal
