This package is named fontpackages and available in the current Fedora releases (as fontpackages-devel and fontpackages-filesystem). Its sources are published on fedorahosted in archive and git (git://git.fedorahosted.org/fontpackages.git) formats.
Its content can be discussed on the Fonts SIG mailing list.
While this package has been created by Fedora for Fedora its content should be pretty generic, and apart from the occasional reference to this wiki as documentation source, it should not include any blatant Fedora-ism. Of course it is a bit rpm-oriented so adapting it to a distribution that uses another package format will demand some work.
