Oxigraph is implemented in Rust. It is composed on a main library, oxigraph and a set of smaller crates used by the oxigraph crate:

• oxrdf, datastructures encoding RDF basic concepts (the model module of the oxigraph crate).
• oxrdfio, a unified parser and serializer API for RDF formats (the io module of the oxigraph crate). It itself relies on:
  • oxttl, N-Triple, N-Quad, Turtle, TriG and N3 parsing and serialization.
  • oxrdfxml, RDF/XML parsing and serialization.
• spargebra, a SPARQL parser.
• sparesults, parsers and serializers for SPARQL result formats (the sparql::results module of the oxigraph crate).
• sparopt, a SPARQL optimizer.
• oxsdatatypes, an implementation of some XML Schema datatypes.
