Regarding the section CommunityRepository#Package_Tags - after inspecting an original package it seems this info is stored in the package.ipk/control.tar.gz/control file of the package using the line "Tags: group::network" for example..
om-maps-berlin_20080430-r0_all.opk -> control.tar.gz -> control: Package: om-maps-berlin Version: 20080430-r0 ... Tags: group::maps ...
Currently the page reads
"Openmoko Inc. hosts a Community Repository as a central service where independent Neo application developers can release projects, so that installing a new application `just works out of the box'. It is a similar concept to the Multiverse repository in Ubuntu."
I dont belive this is true - it sounds more like Ubuntus "Universe" repository. "Multiverse" is for patent encumbered or other non-free software, which the OM repo doesnt seem to be.
