Thanks for putting this together!

I think it would be good to denote which of these fields are required and which are optional. A format for this could be like

`name: str`. Required. . . .

Might also be worth it to split this into it's own cep?

[jaimergp]

I've used "required unless stated otherwise" throughout the CEP, but maybe I can call that explicitly.

What part do you want to split in its own CEP? index.json? The info/ folder?

[soapy1]

Later on the document notes that ./info/paths.json and ./info/hash_input.json are also required. So, those should probably be mentioned here as well as part of this "MUST at least include"

Suggested change

	An extracted conda package is a directory that MUST at least include an `info/index.json` file. Other important metadata files SHOULD be included under `info/`.

Is there a stict requirement for the format of this file? Is it valid if the file exists but is empty?
