Expand the DBpedia ontology

[alvaromorales]

The DBpedia ontology is a fairly extensive DAG of types. In defexpand, we should be able to add to the ontology.

• Create a DAG to model the ontology
• Make it easy (even for someone unfamiliar with Python) to add types and relationships.

This will involve manual work and should be done incrementally. We should contribute back to the DBpedia ontology wiki where possible.

Could you please explain what a DAG is?

Never mind (https://en.wikipedia.org/wiki/Directed_acyclic_graph). The graph can be represented using the NetworkX module, the same one used in WikiMap. Someone could create a wrapper around NetworkX's graph insertion functions, like I did in WikiMap, to create functions such as add_superclass(class, superclass) etc.
