After preliminary reviews by Donald and Daniel, I have now pushed the first complete draft of the JSON-based metadata 2.0 proposal to python.org PEP 426 (metadata 2.0): http://www.python.org/dev/peps/pep-0426/ PEP 440 (versioning): http://www.python.org/dev/peps/pep-0440/ With the rationale and commentary, they're over 3000 lines between them, so I'm not attaching them here. The rationale for many of the changes is at the end of each PEP, along with some comments on features that I have either rejected or deliberately chosen to defer to the next revision of the metadata (at the earliest). Those with BitBucket accounts may also comment inline on the drafts here: PEP 426: https://bitbucket.org/ncoghlan/misc/src/05d3586464b10d6a04a35409468269d7c89a... PEP 440: https://bitbucket.org/ncoghlan/misc/src/05d3586464b10d6a04a35409468269d7c89a... Cheers, Nick. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia
