Based on the Workstation wiki related to appdata addons[1], I created each metainfo.xml for the missing addons including for some applications like Blender.[2]
Nearly all on them are associated with the related applications and it is a matter of filling the missing informations. Each metainfo.xml is validated by appstream-lib so downstream can submit the completed addon appdata to upstream.
For more details, please read http://www.freedesktop.org/software/appstream/docs/sect-Quickstart-Addons.ht...
P.S: I realized I forgot to add .desktop extension but the guideline will suffice.
