Sophia

A Rust toolkit for RDF and Linked Data.

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_inmem defines in-memory implementations of the Graph and Dataset traits from sophia_api.
sophia_term defines various implementations of the Term trait 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_c14n implements RDF canonicalization.
sophia_resource provides a resource-centric API.
sophia_rio is a lower-level crate, used by the ones above.

and finally:

sophia is the “all-inclusive” crate, re-exporting symbols from all the crates above. (actually, sophia_xml is only available if the xml feature is enabled)

Licence

CECILL-B (compatible with BSD)

Testing

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
