There is centralised list (currently in 'free_software_4edu+sci+etc.ods') of programs (or www resources) with descriptions. Now the list is biased towards Education/Science, but it's easy to change.

You can take a look at the general structure:

The categorization system might seem strange but is comfortable and flexible enough.
Now we have 7 *sections* (with ability to have overlapping subsections): Science/Research, Education, Creativity and fun, Office, Internet, Programing, System tools.
There are more specefic/narrow *categories*, which don't overlap.
And there is *keywords* field -- for search purposes only (currently).
Popularity Ratings (based on our own experience, keeping an eye on OS news and some internet listings)

3 main DESTINATIONS for the list info to go: Windows, Linux, WWW: mostly we prepare centralized html (genshi) templates with some if clauses. Also metapackage sources for Linux and lch files for cdbrowserkit.

It is also possible to make *bilingual content * (local + en), or similar way prepare collections *filtered by* rating-limit (for example), which you can toggle.

ps.: Help wished :)
As the system expands, it becomes ugly, so if somenone would help to organize and tidy the code -- I'd be very glad :)
Some automatic tests will be really needed if more people get involved (this is probably my duty)
Also internationalization development might need help (especially http://babel.edgewall.org issues, as we have no experience with them)
web-frontend would rock! any (python) suggestions?
Theming for html/templates is also nice idea
Screenshots and logos are also needed (now I took some from atveries.lv, theopendisc.com, wikipedia.org, /usr/share/icons, /usr/share/pixmaps)
