[Catalog-sig] PyPI improvements

Howdy. I just recently posted some ideas for PyPI
(http://blog.colorstudy.com/ianb/weblog/2004/06/15.html#P123), but some
of the basic features I was thinking about should be generally useful:
1. Express relationships between packages. These are relationships
like alternative-implementation, fork, part-of, recommends, requires,
etc. At the moment I'm thinking purely about displaying this
information, not any fancy distutils magic installation of
2. Cache packages. I.e., download a copy of the package, and if the
package disappears then we have a backup.
These are both more important when dealing with smaller pieces of code
-- code that is part of a more interdependent ecosystem (1), and code
that is more transient (2) -- but these apply just as well to
The other thing that might be useful is some improved categorization of
code. The Trove categories are... well, they are stupid. No fault of
anyone here. CPAN's much more coarsely-grained categories are much
better, in my opinion (Acme, AI, Algorithm, Apache, AppConfig, Archive,
Array, and so on: http://www.cpan.org/modules/by-module
But even more coarsely-grained than that, there are classes of package.
Right now we have libraries and applications. I'd like to add modules
-- though the name is vague, I'm thinking of code on the sophisticated
end of the Python Cookbook entries. Small, reusable, and not worth
distutilifying (I just can't imagine making a whole package for one
100-line module, nor can I imagine using such a package).
When you're looking for code, each of these is quite different from the
others -- for any search, you will probably be interested in any of
these (a library to use, or a module or application to borrow from).
Right now we're neither here nor there, as people don't think to add
applications to PyPI, and the trove categories are inappropriate for
On top of this is the infrastructure issue, which probably also has to
be dealt with before moving forward much (i.e., SQLite and CGI).
Concurrent updates to a SQLite database from multiple processes scares
the crap out of me. But it doesn't look like that should be too hard
