README.md

RDF.ex

An implementation of the RDF data model in Elixir.

The API documentation can be found here. For a guide and more information about RDF.ex and it's related projects, go to https://rdf-elixir.dev.

Migration guides for the various versions can be found in the Wiki.

Features

fully compatible with the RDF 1.1 specification
support of the RDF-star extension
in-memory data structures for RDF descriptions, RDF graphs and RDF datasets
basic graph pattern matching against the in-memory data structures with streaming-support
execution of SPARQL queries against the in-memory data structures with the SPARQL.ex package or against any SPARQL endpoint with the SPARQL.Client package
RDF vocabularies as Elixir modules for safe, i.e. compile-time checked and concise usage of IRIs
most of the important XML schema datatypes for RDF literals
support for custom datatypes for RDF literals, incl. as derivations of XSD datatypes via facets
sigils for the most common types of nodes, i.e. IRIs, literals, blank nodes and lists
a DSL resembling Turtle to build RDF descriptions or full RDF graphs in Elixir
implementations for the N-Triples, N-Quads and Turtle serialization formats (including the respective RDF-star extensions); JSON-LD and RDF-XML are available with the separate JSON-LD.ex and RDF-XML.ex packages
validation of RDF data against ShEx schemas with the ShEx.ex package
mapping of RDF data structures to Elixir structs and back with Grax

Contributing

There's still much to do for a complete RDF ecosystem for Elixir, which means there are plenty of opportunities to contribute. Here are some suggestions:

more serialization formats, like RDFa, N3, CSVW, HDT etc.
more XSD datatypes
improving the documentation

See CONTRIBUTING for details.
