RDFSharp is a lightweight open source C# framework designed to ease the creation of .NET applications based on the RDF model, representing a straightforward didactic solution for start playing with RDF and Semantic Web concepts. With RDFSharp it is possible to draft .NET applications capable of modeling, storing and querying RDF data.

RDFSharp has a modular API made up of four layers:

    • Create and manage RDF models (resources, literals, triples, graphs, namespaces, datatypes, ...);
    • Exchange them using standard RDF formats (NTriples, TriX, Turtle, RDF/XML);
    • Create and manage RDF stores backing on memory or on different SQL engines (Firebird, MySQL, SQLite, SQL Server);
    • Create and manage RDF federations as virtual stores giving integrated query access to multiple stores;
    • Create and execute SPARQL queries on graphs, stores and federations to fluently query RDF data;
  • SEMANTICS (under development)
    • Create, manage and exchange RDF ontologies (classes, properties, facts, ...);
    • Create and execute RDFS/OWL reasoners on them, materializing inferred RDF data;
