Wiki systems make it easy to edit documents online, which makes wikis a compelling tool for document collaboration. Current wiki formats, however, don't allow for the kind of reuse that the DITA was designed to enable.

Eric Armstrong of Sun believes it may be possible to implement some of DITA's best features using a combination of JavaScript and CSS. He suspects it can be done most easily using a Ruby-based Wiki like MediaCloth. See Eric's blog, 'Wikis, Docs, and the Reuse Proposition' for more on this.
