RDFSharp is a lightweight 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.

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 and manage RDF ontologies (classes, properties, constraints, facts);
    • Create and apply RDF reasonings on them, materializing inferred RDF data;
