== Data design ==

http://www.mediawiki.org/wiki/Extension:Semantic_Forms#Data_design_issues

- 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.

== Discussion ==

Categories can be hierarchical; properties can't (yet).


== 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:

 {{ #vardefine: some_variable_name | {{#show:{{PAGENAME}}| ?propertyname}} }}
(silent) or
 {{ #vardefineecho: some_variable_name | {{#show:{{PAGENAME}}| ?propertyname}} }} (with output)

Further down in the page you can write

 {{ #var: some_variable_name }}

=== Specific searches ===

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

=== Hiding set data ===

  <nowiki>[[propertyA::{{{propertyA|}}}|]]</nowiki>

By adding the | after the enclosing }}}, the property value will not show.

For multi value properties:

  <nowiki>{{#arraymap:{{{Eating disorders behaviors|}}}|,|x|[[Eating disorders behaviors::x|]]}}</nowiki>

== Misc ==

=== Enable links in property values ===

 $smwgLinksInValues = true;

=== Must add namespaces to config ===

Otherwise they won't have semantic properties.

$smwgNamespacesWithSemanticLinks array
