Relation Graph module

Module for representing Relation Graphs.

The core concept in a relation graph is an Edge, which consists of

• subject
• predicate
• object

When mapping from OWL, an Edge corresponds to one of:

• A SubClassOf B, where B is a named class, and the predicate is rdfs:subClassOf
• A SubClassOf P some B, and the predicate is P
