appstream in Plasma

[Jonathan Riddell]

Martin's thread on metadata got me wondering about if we should have
appstream files in Plasma.  It would be nice to have plasma-desktop in
software installers for people who run another desktop and want to
install it.  There's also applications like system settings (which has
dozens of plugins), khotkeys and kinfocenter which may or may not be
useful for appstream.

Any advise Matthias?
