An implementation of the RDF data model in Elixir.
Migration guides for the various versions can be found in the Wiki.
- 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
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
