SUSE had 'common.pkd' years ago and still uses 'susetags' for the
on-media metadata.

Both are plain text dumps with the possibility to include translations.
Nothing to gain here from a parsing effort perspective.

I'd rather see a future 'createrepo' format to put some computing
effort at the creation of the metadata in order to relief all clients
from repeating the work. String indexing would be the prime example.
