RDFSharp has a modular API made up of four layers (docs):
- RDFSharp.Model
- Create and manage RDF models (resources, literals, triples, graphs, namespaces, ...)
- Exchange them using standard RDF formats (N-Triples, TriX, Turtle, RDF/Xml)
- Create and validate SHACL shapes (shape graphs, shapes, targets, constraints, reports, ...)
- RDFSharp.Store
- Create and manage RDF stores for context-aware modeling of RDF data (quadruples)
- Exchange them using standard RDF formats (N-Quads, TriX)
- RDFSharp.Query
- Create and manage RDF federations giving integrated query access to multiple data sources
- Create and execute SPARQL queries on graphs, stores, federations and SPARQL endpoints
- RDFSharp.Semantics
- Create and manage OWL-DL ontologies (classes, restrictions, properties, facts, assertions, annotations, ...)
- Validate ontology T-BOX and A-BOX against a customizable set of RDFS/OWL-DL constraint rules
- Create OWL-DL reasoners exploiting an extensible set of RDFS/OWL-DL inference rules
- Create and manage SKOS glossaries, thesauri and classification schemes with a friendly and powerful API
