OCP2KG: Ontology Change Propagation to Knowledge Graphs

OCP2KG is a tool for propagating ontology changes to declarative mappings. The tool requires as input the updated version of the ontology in OWL, the outdated mappings in RML, and the change data, that has to be in RDF following the OWL Change Ontology model.

How to run it?

python3 -m pip install -r requirements
python3 evol_kg.py -c path_to_change_kg.nt -m path_to_old_mapping.rml.ttl -o path_to_new_ontology.ttl -n path_output_mappings.rml.ttl

Options:

-c, --changes_kg_path <arg>        Path to a change KG compliant with OCH
-m, --old_mapping_path <arg>       Path to the old mapping rules (previous version) in RML
-o, --ontology_path <arg>          Path to the new version of the ontology
-n, --new_mappings_path <arg>      Path to the output files, updated version of the mapping rules
-y, --yarrrml                      Output mappings will be also translated to YARRRML (RML turtle by default)
