Nice! If there are multiple of those formats present, does it get the
data from just one? Or does it get data from all of them and combine

It probably doesn't matter for most cases, but since setup.py runs
arbitrary code, it's possible for it to install different modules in
different situations - or even select modules at random, if you really
want to confuse tools like this. ;-)
This is why my own efforts at indexing focused on wheels - you can be
sure of exactly what a wheel contains. My wheel-indexing tool 'wheeldex'
is here, if there's any code or ideas there that you can use:https://github.com/takluyver/wheeldex

Neat, that's precisely one of the use cases I was thinking of for an
index. The other thing I'm interested in is providing an interface to
install modules by their import name rather than their PyPI name; I
think your index should work for that as well. I'll dig into the code of
both PyPIContents and Pip Sala Bim more soon.
