Distinguish between the two uses of the term "schema"

[meldckn]

There's the schema.json sense vs the whole data directory sense (authoring your social schema as defining schema.json, actions.json, cast.json, etc, or the "Load Schema" button in the tool for loading all those files).

It's a source of confusion when talking about the authoring process even among Ensemble experts, and probably more confusing for novices. We should pick and stick with different terms for each thing. Maybe "schema" for the schema.json sense, and "domain" for the whole thing?
