yet anothers things to do: Appstream, comps and remix

Hello,  Adam Williamson wrote today in reply of one question (made by me) :  "Hmm, actually, maybe it currently doesn't, but it definitely has before: http://download1.rpmfusion.org/free/fedora/updates/testing/20/x86_64/co mps.xml But basically, any repo can have comps data and dnf will respect it; you can set up an external repo with comps data that lists some package from that repo as being in the `standard` group, for instance, and when it installs the `standard` group, dnf will include that package. AFAIK this has always been intended to work. I'm not sure how often it gets tested. " Goggled and found http://rpmfusion.org/comps , so maybe we should add  rpmfusion-comps repo (to archive) , in     https://github.com/rpmfusion-infra/rpmfusion-comps/    like fedora-comps , btw comps was talked here in rpmfusion in 2007 [1] , and if we need generate comps.xml , we also may talk in Appstream , we need generate something isn't it ? And since remxis depends on comps.xml (If I am correct), also talk about RPMFusion remixs, not propose generate the remixs , but at least update remix specs [2], and be able do remix in a local machine .  About appstream [3], can I add/update the missing packages for Fedora 23 ? and close the review request after that?  Cheers,  [1]  http://lists.rpmfusion.org/pipermail/rpmfusion-developers/2007-October/ 000042.html [2]  https://pkgs.rpmfusion.org/cgit/?q=remix [3] https://bugzilla.rpmfusion.org/show_bug.cgi?id=3657 https://bugzilla.rpmfusion.org/show_bug.cgi?id=3658 -- Sérgio M.
