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 realize .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 (N-Triples, TriX, Turtle, Xml);
    • Create and manage RDF stores backing on memory or on different SQL engines (Firebird, MySQL, PostgreSQL, SQLite, SQL Server);
    • Exchange them using standard RDF formats (N-Quads);
    • 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;
    • Create, manage and validate OWL-DL ontologies (classes, properties, restrictions, facts, relations, ...);
    • Validate them against RDFS/OWL-DL specifications to report warning/error evidences;
    • TBD: Materialize inferred knowledge through RDFS/OWL-DL reasoning;
