ActionMarket

ActionMarket is a feature of the MoinMoin Market Model. See for example http://twistedmatrix.com/users/jh.twistd/moin/moin.cgi/ActionMarket

With this, it would be ridiculously easy to support APC Action Apps and any barcode and betting extensions required to deal with score reality.

TikiWiki and MediaWiki would be stupid not to copy this architecture - see Alternate wiki-implementations for more requirements and comparisons.
