A Rust toolkit for RDF and Linked Data.

Build Status Latest Version Coverage Status

It comprises the following 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 implementations of the TTerm trait from sophia_api.
  • sophia_inmem defines in-memory implementations of the Graph and Dataset traits from sophia_api.
  • sophia_turtle provides parsers and serializers for the Turtle-family of concrete syntaxes.
  • sophia_xml provides parsers and serializers for RDF/XML.
  • sophia_jsonld provides preliminary support for JSON-LD.
  • sophia_indexed and sophia_rio are lower-level crates, used by the ones above.

and finally:

  • sophia is the “all-inclusive” crate, re-exporting symbols from all the crates above.


CECILL-B (compatible with BSD)


The test suite depends on the [the JSON-LD test-suite which is included as a git submodule. In order to run all the tests, you need to execute the following commands:

$ git submodule init
$ git submodule update
