Getting Started with Virtual Graphs

Join this training webinar to learn how to map relational data sources to the RDF graph model and query external relational data sources as virtual graphs. Stardog supports the standard W3C R2RML mapping language for defining how data in a relational system maps to RDF graphs. We’ve created the Stardog Mapping Syntax to simplify the process of writing these mappings. Once the mapping is created, Stardog seamlessly supports both federation (live query) and materialization (extraction) methods to access relational data.
