[arch-general] improving the app stream data

hi all
I'm writing in to ask how I can help arch improve it's app stream
data, which is largely what gnome software depends on to be able to
install and find software. As it stands now there are a lot of
packages missing data, so you often get "no application found" when
using gnome software to search for them. A good example is orca, the
screen reader. Another issue is using gnome software to find software
for mime types the system doesn't know how to handle. Often you'll get
sorry we couldn't find any software to handle this mime type, when
software does exist. Does anyone know how the app stream system works
and can you point me to docs and standards so I can read up on it?
Once I've got that down, where can I pull down the source appstream
data arch uses so I can start improving it? I've got the
archlinux-appstream package installed, but I'm not sure if I can edit
the data with a running package and it will be picked up automatically
or if I need to edit the data and then generate a new package. Sorry
for my ignorance I'm completely new at all of this stuff. Any help
would be greatly appreciated.
Thanks for reading
