Semantic MediaWiki Extensions 0.4 released

Semantic MediaWiki aims at the inclusion of "semantic web" features into MediaWiki, the software powering Wikipedia [1]. Users are enabled to enrich wiki-articles with bits of machine-readable information in a simple and integrated fashion. This data is used for enabling powerful search functions in the wiki, and allows developers to write software that harvests the wiki's knowledge for external use. Details are available on the project homepage and testsite [2].

Release 0.4 [3] strongly improves the search capabilities and performance, and includes improved datatype support. In detail, the new features in 0.4 are:

  • Support for inline queries, which allow to ask queries within articles, the
    answers of which are included into the displayed page. Queries feature
    conjunction, datatype support, nested queries, customizable output formats,
    and MediaWiki category search.
  • Improved ontology import feature.
  • Configurable infobox: infobox can be hidden if empty, or switched off
    completely. This also works around a bug with MediaWiki galeries.
  • Improved output for Special:Relations and Special:Attributes.
  • Support for EXP-notation with numbers, as e.g. 2.345e13. Improved number
    formating in infobox.
  • More datypes with specific unit support: mass and time (duration).
  • Experimental support for date/time datatype.
  • Prototype version of Special:Types, showing all available datatypes with
    their names in the current language setting.
  • More efficient storage: changed database layout, indexes for faster search.
  • Cleaned up code, bugfixes, bugfixes, and some more bugfixes.

Current development activities and next steps are documented online [4]. Further PHP development support is always welcome. Development and usage is discussed on our mailinglists [5] and also in the Semantic Wiki Interest Group [6].
