An implementation of the [RDF](https://www.w3.org/TR/rdf11-primer/) data model in Elixir.

For more about RDF.ex and it's related projects, go to <https://rdf-elixir.dev>.

## Features

- fully compatible with the RDF 1.1 specification
- in-memory data structures for RDF descriptions, RDF graphs and RDF datasets
- ability to execute SPARQL queries against the in-memory data structures via the [SPARQL.ex] package or against any SPARQL endpoint via the [SPARQL.Client] package
- support for RDF vocabularies via Elixir modules for safe, i.e. compile-time checked and concise usage of IRIs
- XML schema datatypes for RDF literals (not yet all supported)
- sigils for the most common types of nodes, i.e. IRIs, literals, blank nodes and lists
- a description DSL resembling Turtle in Elixir
- implementations for the [N-Triples], [N-Quads] and [Turtle] serialization formats
    - [JSON-LD] is implemented in the separate [JSON-LD.ex] package


## Contributing

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

- more serialization formats
    - [RDFa]
    - [RDF-XML]
    - [N3]
    - et al.
- more XSD datatypes
- improve documentation

see [CONTRIBUTING](CONTRIBUTING.md) for details.
