Sorry I didn't think of this sooner, but I don't see in the PEP a brief summary of precisely what metadata is required. From the "Core Metadata" section I infer that a project with *only* Name and Version (and Metadata-Version, which will be supplied by the build tool) is valid. That's fine, but notably more permissive than earlier versions of the spec. One thing I see is "Index servers MAY require that this field be provided" for some metadata (e.g., Summary") which is fine, I guess, but implies that somewhere, the rules for PyPI should be documented. Also, is it true that build tools MAY require certain fields to be provided? I'm pretty sure setup.py sdist does at present. My logic here is that previously I would go to the metadata PEP to check precisely what fields I need when building my project. Now, I'm not sure where I'd go. (Note that most of my projects are internal only, so it's actually the extra distutils/setuptools requirements that interest me more than those of PyPI...) I can imagine the answer would be "the documentation of the individual tool" - but in reality said documentation often isn't present (possibly because earlier metadata PEPs documented this information centrally) Paul
