I've been looking that the same thing - a more flexible metadata format which directly maps to dicts - but I used YAML, as looking at too much JSON gives me eye-strain from all the extraneous quotes and braces. I believe that JSON is the right format to use at the moment, because PyYAML still has some bugs which I've run into while doing this work (also, of course, it's not in the stdlib). As the formats are readily interchangeable, there might be interest here in looking at the package.yaml that I've come up with. Since the metadata needs to support both the existing metadata and the additional things that e.g. setuptools supports via additional kwargs to setup(), I put together an ugly hack where I essentially mocked parts of distutils and setuptools, including the setup() call. This allows me to generate the YAML format automatically from most distributions on PyPI, using their setup.py. Here's a GIST with sample package.yaml files automatically generated from PyPI downloads of SQLAlchemy 0.7.8, Jinja2 2.6, Flask 0.9 and wheel 0.9.4. https://gist.github.com/3803556 The JSON format of the metadata is actually appended as a comment on the last line of the YAML metadata (I use that to report YAML bugs). I've not yet documented the schema for the metadata, as I'm still thinking about the details. I ran my hack on around 18,000 PyPI releases (basically, all the latest releases which are hosted on PyPI). For all but around 1300, I was able to generate package.yaml files. The ones which failed are those where no setup.py is present, or it's present, but can't be imported because it assumes that some third-party package is available. Comments welcome.
