Sophia

A Rust toolkit for RDF and Linked Data.

It comprises the following crates:

• Core crates:
  • sophia_api defines a generic API for RDF and linked data, as a set of core traits and types; more precisely, it provides traits for describing
    • terms, triples and quads,
    • graphs and datasets,
    • parsers and serializers
  • sophia_iri provides functions, types and traits for validating and resolving IRIs.
  • sophia_term defines various implementations of the Term trait from sophia_api.
  • sophia_inmem defines in-memory implementations of the Graph and Dataset traits from sophia_api.
• Parsers and serializers
  • sophia_turtle provides parsers and serializers for the Turtle-family of concrete syntaxes.
  • sophia_jsonld provides parsers and serializers for JSON-LD.
  • sophia_xml provides parsers and serializers for RDF/XML.
  • sophia_rio is a lower-level crate, used by the ones above.
• Other
  • sophia_c14n implements RDF canonicalization.
  • sophia_isomorphism provides functions to determine if two graphs or datasets are isomorphic.
  • sophia_sparql_client provides a client for the SPARQL 1.1 Protocol.
  • sophia_resource provides a resource-centric API.
• All-inclusive
  • sophia re-exports symbols from all the crates above, with the following provisio:
    • sophia_jsonld is only available with the jsonld feature
    • sophia_sparql_client is only available with the http_client feature
    • sophia_xml is only available with the xml feature

In addition to the API documentation, a high-level user documentation is available (although not quite complete yet).
