RDFSharp has a modular API made up of three layers:

• RDFSharp.Model
• Create and manage RDF models (resources, literals, triples, graphs, namespaces, ...)
• Exchange them using standard RDF formats (N-Triples, TriX, Turtle, RDF/Xml)

• RDFSharp.Store
• Create and manage RDF stores backing data on memory or SQL Server (see extensions)
• Exchange them using standard RDF formats (N-Quads, TriX)
• Create and manage RDF federations giving integrated query access to multiple stores

• RDFSharp.Query
• Create and execute SPARQL queries on graphs, stores, federations and SPARQL endpoints
