The @repo has the same "dirty hack" feel to it,
as the current @collection does for names... ?

But I guess "installed" was something of a kludge
anyway, using a boolean there seems more natural.

Probably 1, but either is fine as far as I care.

i.e. neither are true repos, but field is "data"

Easy enough to modify:

        if package.installed:
            data = 'installed'
        elif self._channel_is_local(channel):
            data = 'local'
        else:
            data = channel.getAlias()

I added it as an RFE for Smart Package Manager:

In the PackageKit backend, it would be used like:

    repoid = smart.pkgconf.getOrigin(package)
