Introduction
A library for W3C Provenance Data Model supporting PROV-O (RDF), PROV-XML, PROV-JSON import/export
- Free software: MIT license
- Documentation: http://prov.readthedocs.io/.
- Python 3 only.
Features
- An implementation of the W3C PROV Data Model in Python.
- In-memory classes for PROV assertions, which can then be output as PROV-N
- Serialization and deserialization support: PROV-O (RDF), PROV-XML and PROV-JSON.
- Exporting PROV documents into various graphical formats (e.g. PDF, PNG, SVG).
- Convert a PROV document to a Networkx MultiDiGraph and back.
Uses
See a short tutorial for using this package.
This package is used extensively by ProvStore, a free online repository for provenance documents.
Roadmap
The library is undergoing a staged modernisation (tooling, type hints, tests, documentation, standards conformance), a batch of bug fixes, and new format support. See ROADMAP.md for the plan and the 2.x API-stability promise. Feedback is welcome on the issue tracker.
Supported versions
The latest 3.x release receives all fixes. This 2.x line receives security fixes only; 2.5.4 was the last release to carry bug fixes back-ported from 3.x. 1.x and earlier no longer receive fixes. See SECURITY.md for the full support table and how to report a vulnerability.
