Mosts hosts don't even have RDF metadata. DOAP is just one vocabulary,
I agree it should be shipped with hosts though, and all data should
probably be in the same document (doap stuff, supported extensions,
whatever else). This would be a good precedent to set.

This is another reason for automatically generating it. Considering all
the versions, and all the permutations of hosts/plugins, doing it as a
human maintained static set of documents isn't really feasible.

The point is that having this stuff scattered all over the place doesn't
really solve the problem. We need to establish a standard format for
this data, gather the data (in a distro-agnostic format (RDF)), write
the tools, and get it done. People can package the results and
integrate it with whatever other things as they please.
Integration with packaging systems might be nice (for people that use
those distros) but doesn't solve the problem. First thing's first and
