I have two new extensions to through into the mix: 1) Graphviz embedding extension. It generates Graphviz (http://www.graphviz.org) images from embedded markup. Although one already exists, I couldn't find the source code, so I wrote a new one. 2) Graph generating SpecialPage. This extension allows you to query your wiki for both XML and Graphviz markup of subsets of your wiki. As an added bonus, the content can be transparently included in pages so dynamic graphs (images) of relations can be generated. The extensions can be downloaded from http://opensource.case.edu/projects/MediaWikiHacks/ A live example of these extensions is the Case Western Reserve University Wiki (http://wiki.case.edu). Some links of interest are: http://wiki.case.edu/Special:Graphs http://wiki.case.edu/Category:Staff http://wiki.case.edu/Category:ITS_Employees http://wiki.case.edu/CaseWiki:Categories As you can see, for all smaller category pages, a graph of the category layout is automatically generated. (Yes, I know about the font issues). This extension is a work in progress and is a little rough around the edges. I welcome any input others should provide and am open to suggestions for future possibilities. Gregory Szorc gregory.szorc(a)case.edu
