Tool Overview

Semantic MediaWiki (SMW) is a free extension of MediaWiki, the wiki-system powering Wikipedia, that helps to search, organize, tag, browse, evaluate, and share the wiki's content. While traditional wikis contain only texts which computers can neither understand nor evaluate, SMW adds semantic annotations that bring the power of the Semantic Web Technologies to the wiki.

What's New

SMW 1.5.0 released

March 07, 2010
This new version has seen a significant number of internal changes that will (hopefully) not affect users or extension developers, but that improve the maintainability and extendability of SMW. There are also some "visible" new features:

  • Inverse properties
  • New query parameters
  • Added and improved datatypes (but coordinates were moved to Semantic Maps)
  • Extended interface for Special:Ask

Refer to the release information for details, and to the installation and upgrade instructions.

At A Glance Details

Installation Level: Intermediate - technical assistance may be required, download may require supporting infrastructure or software

Extension Information

First Meeting of Semantic MediaWiki Users was held November 22 - November 23, 2008.

This first meeting of Semantic MediaWiki users was held at the offices of the Monitor Group, at 2 Canal Park in Cambridge, MA. About 30 people gathered. The first day covered many aspects of SMW and its related extensions; including technical, usability, training, "best practices", marketing and business-development issues. The Sunday, "tech day" meeting covered in-depth technical aspects of some proposed additions to the SMW system.

Information (including minutes of each days activities) on the meeting can be found at SMW Nov.2008 Meeting.
