Type theory friends: is there any work out there looking into the relationship between indexed inductive types and inductive recursive types?

Thanks, I'll have a look!
For me the case is I have a universe of binary format descriptions, and an associated family of in-memory representations of those format descriptions:
Format : Type
Repr : Format -> Type

The `Format` version is very convenient but in some cases I’d like to be able to constrain a format to a specific representation, eg. `FormatOf A`.

An am also pondering tracking the sizes of formats as well, which could start getting unwieldy for my poor users with indexed types.
