gah! It's there in document I linked to, I forgot to list it here. Of
course it's needed, we will most probably model it after OAF (since it's
rather easily comprehensible mechanism) + backend for storing the info.

Yes, but in course of brainstorming, we had been pointed out that it's
in general impossible to create working UI for any data simply from
types description (specifically, it's not about laying it out in a
pretty way, but about making sure that logic behind it works correctly,
so that checkboxes toggle sensitivity of related widgets, dates enetered
are sensible, etc.). This could be probably solved by using programming
language like python embedded in description, or maybe forging our own
declarative pseudo-language based on XML, but it's a project on its own,
and we take into account (however unpleasant) possibility of failing
here. We're gonna try it before, however ;)

Sorry, nothing yet. We discussed it much, but coding is only starting
now (it was stalled partly due to end of academic year)
