Oxigraph-handlegraph

Oxigraph is a graph database implementing the SPARQL standard.

This is a fork of oxigraph that includes rs-handlegraph. The purpose is to make pangenomic GFA-files accessible with SPARQL queries.

Also, some parts of Oxigraph are available as standalone Rust crates:

  • oxrdf, datastructures encoding RDF basic concepts (the oxigraph::model module).
  • oxrdfio, a unified parser and serializer API for RDF formats (the oxigraph::io module). It itself relies on:
    • oxttl, N-Triple, N-Quad, Turtle, TriG and N3 parsing and serialization.
    • oxrdfxml, RDF/XML parsing and serialization.
  • spargebra, a SPARQL parser.
  • sparesults, parsers and serializers for SPARQL result formats.
  • sparopt, a SPARQL optimizer.
  • oxsdatatypes, an implementation of some XML Schema datatypes.
