As part of the requirements gathering for the RDFIO project, I needed to find out a bit more about websites currently using Semantic MediaWiki. One of the presentations at SMWCon was by Yolanda Gil, on the subject of Provenance Bee, an extension of WikiApiary. This pointed me towards a useful source of data on wiki usage.
The WikiApiary project offers fascinating insights into websites which use MediaWiki software, from the sheer breadth of subjects covered to the variety in the use of categories and the dynamics of editing activity. As well as being able to view the details for each individual wiki, there are aggregated statistics and graphs on extensions, skins, wikifarms, hosting providers and software versions.
The page on the Semantic MediaWiki extension had some useful information on the versions in use on the tracked sites. The main statistics page had information on the versions of PHP and MySQL in use, but this was for all wikis, so the site didn’t seem to have the information I needed.
However, WikiApiary is itself a semantic wiki, so I just needed to ask it the right question. With a few changes to the #ask semantic queries from the main statistics versions, I was able to add information on the software versions used specifically for semantic wiki websites. Hopefully this will be of use to other developers on SMW-related projects.
