I'm not quite sure what you mean here. Are you talking about which
file to use, or which property are required, or something else?

Not at the moment, but it's one of the things that are made much
easier by using a formal data format.

Well, it's kind of the point though. Free-form text was impossible to
parse in a generic way, and you couldn't build any generic tools upon
it. YAML provides that.
