Day 5 (Dec 18)
I played with the site after some time.
1) I searched drupal.org to find out what we need to find out and what I found is that we should first decide
what we need to find out ;-)
So:
a) we need a way to design our node-type "Open problem"
b) we need a way to attach "categories" (like area) to the nodes
c) we want a way how to search/sort
a) is done by Flexinode and CCK. The latter is supposed to be better, but still somewhat buggy.
(For more details: http://webschuur.com/node/669)
b) is done by (standard) taxonomy vs. (new) category module. The latter seems to be better,
but again, some claim it buggy.
c) for this we should use views -- and this means we cannot use Flexinode in a)
2) What seems to work easily with Category, is creating menu structure for Area (etc.).
I don't know how to do navigation via "pull-down" menus that would be context-sensitive. ;-(
The "only" trouble is that I don't know how to assign Category to nodes ;-(((
May be the taxonomy module is still in the way???
