A simple implementation of the OWL2 RL Profile, as well as a basic RDFS inference, on top of RDFLib, based on forward chaining.

This package is a Python library that also contains a couple of scripts:

• scripts/RDFConvertService: a CGI script to invoke the library. It may have to be adapted to the local server setup.
• scripts/owlrl: a script that can be run locally on to transform a file into RDF (on the standard output). Run the script with -h to get the available flags.

This package requires RDFLib 7.1.3 as its only dependency and it can be installed from the Python Package index in the usual way:

pip install owlrl

or

poetry add owlrl

This package can run inference according to RDFS and/or OWL-RL.

For details on RDFS, see the RDF Semantics Specification; for OWL 2 RL, see the OWL 2 Profile specification.
