People who have added themselves to this category may be interested in TonyBot, part of a project to make an on-wiki query system for Wikipedia and other large MediaWiki-based wikis.
Because I'm a Schemer I've written the bot framework in Scheme, and the query language is a dialect of Chicken Scheme, but the basic idea is applicable to any scripting language. I've been running private queries based on the bot framework for a couple of months now and I'm currently running simple tests of the user interface, which allows any Wikipedian to write a script, and any other Wikipedian to make use of it. A sample script, which is working now, is at User:Tony Sidaway/scripts/search. It's rather more complex than it should be because I'm still developing a standard library that will enable concise query scripts to be written. I am also working n a separate-compilation facility so that scripts can use code units spread across several wiki pages.
If anybody is interested in this project, please contact me on my talk page. --Tony Sidaway 15:15, 5 September 2007 (UTC)
