Relation Graph, Python Port

This is a minimal implementation of relation-graph in Python

The goal is to reason over a minimal subset

• subClassOf
• someValuesFrom
• transitive properties
• property chains

To run:

run_relation_graph("tests/input/test.csv", "tests/output/results.csv")

• input must be csv
• headers must be subject, predicate, object
• domain entities can be any syntax, rdf/owl terms must be CURIEs
• rows are either:
  • relation graph direct edges
  • triples of the form PRED,rdf:type,owl:TransitiveProperty

See tests/input for details

TODO

• reflexive edges
• relax equivalence to paired subClassOf
• compare with scala relation-graph
• property chains
