# RDF.ex [![CI](https://github.com/rdf-elixir/rdf-ex/workflows/CI/badge.svg?branch=master)](https://github.com/rdf-elixir/rdf-ex/actions?query=branch%3Amaster+workflow%3ACI) [![Hex.pm](https://img.shields.io/hexpm/v/rdf.svg?style=flat-square)](https://hex.pm/packages/rdf) An implementation of the [RDF](https://www.w3.org/TR/rdf11-primer/) data model in Elixir. The API documentation can be found [here](https://hexdocs.pm/rdf/). For a guide and more information about RDF.ex and it's related projects, go to . Migration guides for the various versions can be found in the [Wiki](https://github.com/rdf-elixir/rdf-ex/wiki). ## Features - fully compatible with the RDF 1.1 specification - 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 - execute [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 - define 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 description DSL resembling Turtle in Elixir - implementations for the [N-Triples], [N-Quads] and [Turtle] serialization formats; [JSON-LD] and [RDF-XML] are available with the separate [JSON-LD.ex] and [RDF-XML.ex] packages - validate data against [ShEx] schemas via the [ShEx.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, like [RDFa], [N3], [CSVW], [HDT] etc. - more XSD datatypes - improving documentation see [CONTRIBUTING](CONTRIBUTING.md) for details. ## Consulting and Partnership If you need help with your Elixir and Linked Data projects, just contact or visit ## License and Copyright (c) 2017-2020 Marcel Otto.
