The OBO Foundry registry runs smoothly using easily edited [Md](https://github.com/OBOFoundry/OBOFoundry.github.io/tree/master/ontology) files that can generate [YAML](https://github.com/OBOFoundry/OBOFoundry.github.io/blob/master/registry/ontologies.yml) and other formats. A base registry like that (perhaps right in YAML) could make things like PRs and review quite easy.
