...but it doesn't include any context...

Ahh, but one-entity, one-file gives most of the context you could want. Currently, I've just started a huge pile of work on defining a new hub for the über-converter, so I'll see how well this holds up moving into the chromista hub design.

This example is a little old, but maybe gives you a good idea of why YAML is a Good Thing™ in this case.
