Questions tagged [graphdb]

Ontotext GraphDB is a semantic triplestore: a database for RDF and OWL data. Use this tag for questions specifically about the Ontotext GraphDB product. For questions that are about graph databases in general (or about other graph database products), use the [graph-databases] tag instead.

In essence, GraphDB™ is a “semantic repository” using ontologies that allow the repository to automatically reason about the data. It works with a flexible and generic physical graph data model allowing for easy interpretation and adoption of new ontologies or metadata on-the-fly. GraphDB™ is packaged as a storage and inference layer (SAIL) for Sesame. Sesame is one of the most popular semantic repositories that supports RDF(S) and all the major syntaxes and query languages related to it. GraphDB is fully SPARQL 1.1 compliant. You can read more about GraphDB™ here. The full documentation can be found here.
