Hi Thomas!
Well.... For e.g. :If you were to group restaurants in various cities under cuisine titles.... You'd have the following logical structure.
New York
- Italian
- French
- Indian
Paris
- Italian
- French
- Indian.
Now, while working with the current categories in mediawiki. If I were to group a restaurant under "Italian" in the city of New York and do the same with a restaurant in Paris. They would both be grouped under the same category "Italian". Whereas I would like them to be in 2 separate areas i.e: an "Italian" sub-category under New York and another "Italian" sub-category under Paris...
Haven't any idea how to achieve it with MediaWiki itself, but what about a workaround?
You could define categories like "Paris/Italian" and "New York/Italian" (no real subpages/subcatagories) or "Italian (Paris)" and "Italian (New York)"? Not very pretty, but it should do the job.
