Distinguishing between Fedora packages a non-Fedora packages is easy
(provided that no non-Fedora package sets the Vendor tag to "Fedora
Project"):

  rpm -qa --qf %{vendor}\\t\\t\\t%{n}\\n|sort

If one wanted to find out whether an installed package is from a
specific repo, that would be more difficult (and not even yumdb
gets updated if a package moves from updates-testing into updates).
