[xwiki-dev] Category (and hierarchical category).

[Vincent Massol]

Hi phl,

Yes this is fully implemented in xwiki and it's actually one of  
xwiki's strengths.

You have 2 possibilites to implement it depending on whether you want  
form editing to enter new data or not:

* if you do then you should implement something as described in the  
FAQ tutorial:
   http://www.xwiki.org/xwiki/bin/view/DevGuide/FAQTutorial

* if not, then you can simply tag your pages
   (see http://www.xwiki.org/xwiki/bin/view/UserGuide/Tags) and the  
query tags in the page where you want to list them using a HSQL query
   (see http://www.xwiki.org/xwiki/bin/view/UserGuide/Programming and  
check the code zone for lots of examples on that).

Thanks
-Vincent
