Oxigraph
Oxigraph is a graph database implementing the SPARQL standard.
Its goal is to provide a compliant, safe, and fast graph database based on the RocksDB key-value store. It is written in Rust. It also provides a set of utility functions for reading, writing, and processing RDF files.
Oxigraph is in heavy development and SPARQL query evaluation has not been optimized yet. The development roadmap is using GitHub milestones. Oxigraph internal design is described on the wiki.
Oxigraph implements the following specifications:
- SPARQL 1.1 Query, SPARQL 1.1 Update, and SPARQL 1.1 Federated Query.
- Turtle, TriG, N-Triples, N-Quads, and RDF/XML RDF serialization formats for both data ingestion and retrieval.
- SPARQL Query Results XML Format, SPARQL 1.1 Query Results JSON Format and SPARQL 1.1 Query Results CSV and TSV Formats.
It is split into multiple parts:
- The database written as a Rust library. Its source code is in the
libdirectory.
pyoxigraphthat exposes Oxigraph to the Python world. Its source code is in thepythondirectory.- JavaScript bindings for Oxigraph. WebAssembly is used to package Oxigraph into a NodeJS compatible NPM package. Its source code is in the
jsdirectory. - Oxigraph binary that provides a standalone command-line tool allowing to manipulate RDF data and spawn a web server implementing the SPARQL 1.1 Protocol and the SPARQL 1.1 Graph Store Protocol. Its source code and instructions (including Docker) are in the
clidirectory. Note that it was previously named Oxigraph server.
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.
* spareval, a SPARQL evaluator.
* spargebra, a SPARQL parser.
* sparesults, parsers and serializers for SPARQL result formats.
* sparopt, a SPARQL optimizer.
* oxsdatatypes, an implementation of some XML Schema datatypes.
The library layers in Oxigraph. The elements above depend on the elements below:
A preliminary benchmark is provided. There is also a document describing Oxigraph technical architecture.
