   In a meeting we (a few members of the SPICE team) had at the
desktop summit together with designers. Its not really a plan plan but
more like a general agreement/understanding for now and we still await
the designers to finalize it all.

  The metadata you mean? Yes, thats going to be in osinfo. I intend to
write a minor that extracts just volume, system and publisher IDs and
a boolean indicating if the ISO is bootable but all that doesn't need
to use libosinfo (though there will be some minor duplication of
code).

  Beagle never really stayed around but Tracker hasn't just been
around for quite some time now but is also a blessed dependency in
GNOME and some of the core hackers of it are trust-worthy GNOME
hackers.

  Yes! You still need dbus session though.
