Data design

- Create a top category for Semantic Classes. I called mine 'Categories'. It holds only categories used to define a 'Is-a' relationship. Doing so has at least two benefits : 1- You can do a query on your core content by restricting it to the 'Categories' level. 2- You can define other categories outside of that structure for whatever your system needs.

MW tricks

If you want to clear out old pages you can delete them and use deleteArchivedRevisions.php to erase the deleted revisions from the database.

Variables

You can make use of the VariablesExtension [1] and store the query (or its result? I'd like to know which one, but in the end it doesn't really matter) in a variable, which is helpful when you need the same query multiple times within a page. It looks like this:

(silent) or

 (with output)

Further down in the page you can write

Specific searches

 
  <inputbox>
  type=search
  width=30
  namespaces=Help**,Wikipedia**,Template** 
  searchbuttonlabel=Search help pages
  bgcolor=#cee0f2
  break=no
  </inputbox>
  

Misc

Enable links in property values

$smwgLinksInValues = true;
