Verify all model fields exposed in various contexts #605

We should produce a spreadsheet that identifies the fields associated with each model, and the view context required to expose them.

For instance, in #603, we're still not quite sure which user attributes should be exposed in which context. It would be best to have a master list to work from (with agreed-upon model attribute names).

Also, as a part of this issue, we should audit the query arguments for collections. As much as possible, they should be consistent.
