It'd be neat to integrate with the growing biomedical knowledge graph space. A few basic ideas

• check out the project cookie cutter https://github.com/Knowledge-Graph-Hub/kg-cookiecutter
• provide refs to external entities (?)

I'm not sure if our data necessarily adheres to the KG/OBO standards but it'd be fun to look into sometime.

This was a) already done in v4 and b) is being expanded upon in dgipy, but probably no need to address it further here
