User:Badon/Extension:Semantic MediaWiki/Manual

Semantic MediaWiki is a system. This documentation aims to show you how to achieve your goals using Semantic MediaWiki and available related extensions. An integrated approach is needed to make sense of how to use SMW - which itself aims to do the same thing for the data in a wiki.

Shortcomings and limitations

 * Cannot traverse property "chains" easily with ordinary queries.
 * "Lite" version for Wikipedia will not be able to do queries at all.

Needed semantic "meta" properties

 * Page name
 * Page categories
 * Page templates
 * Page forms
 * Page number of edits
 * Page number of links outbound
 * Page number of links inbound
 * Page size
 * Page number of views
 * Page modification date - already implemented
 * Page creation date
 * Page creator
 * Page editors
 * Page last editor
 * User registration date
 * User number of edits

Of those in the above list, these are currently doable, mostly with workarounds, and should have lower priority:


 * Page name - store manually with magic word
 * Page categories - store manually
 * Page templates - store manually
 * Page forms - store manually
 * Page modification date - already implemented

This list of needed meta-properties is taken from these three sources:


 * http://smw.referata.com/wiki/Add_page_metadata_properties_to_a_page_(using_DPL)
 * https://bugzilla.wikimedia.org/show_bug.cgi?id=13151
 * https://bugzilla.wikimedia.org/show_bug.cgi?id=29988 (mentions they need need to show in SMW factbox)

And consolidated here:


 * https://bugzilla.wikimedia.org/show_bug.cgi?id=30610

Additionally, metaproperties do not show up in the SMW factbox:
