You are missing my point, I'm saying that ostree based images are very
different from the GNOME live CDs that are already listed in libosinfo
database, and as such, they should go to a different namespace, ie
something that is not <os id="http://gnome.org/3.10">.
If someone was to make a GNOME 3.10 live CD, we want that live CD to get this
id, and we will be stuck if we used it first for ostree images.

What I mean is if we tell application developers to lookup the osinfo
database entry whose id is 'http://gnome.org/3.10' to get hardware
requirements for ostree images, it would not be nice to change our mind
later and tell them that now they should be using 'http://ostree/3.10'.
We don't have an API in libosinfo which returns the id to lookup for
ostree images, so what you are suggesting is that we tell applications they
can hardcode a given ID, right?
