--- Comment #3 from Igor Gnatenko ignatenko@redhat.com --- (In reply to Jeremy Cline from comment #2)
Well some of the fedmsg consumers use the prefix (https://admin.fedoraproject.org/pkgdb/package/rpms/python-fedbadges/) and some don't (https://admin.fedoraproject.org/pkgdb/package/rpms/github2fedmsg/). I'm not sure which is more appropriate and I don't really have a strong preference. I assumed that most things that just provide a Python module and aren't meant to be used as freestanding applications got the python- prefix. I thought this was documented somewhere, but I can't seem to find it so I might have just made that up.
Yeah, basically if package provides module and it's supposed to be used (I mean `import foo`), then it should be python-. If it's just standalone application (isn't the-new-hotness like this?) - then without.
