jKey is a combination of standard mediawiki templates with javascript code to provide a simple solution for a simple task: publish plain traditional dichotomous or polytomous keys as documents on the web, edit and illustrate them collaboratively on the web, and finally either view them in printable overview mode or play them interactively (step-by-step, with revisionable/confirmable history and uncertainty flagging). jKey uses a mediawiki installation as its basis. Keys can be edited in the normal wiki-editor as well as in a custom, form-based editor. All javascript code is GPL licensed. It is available and editable directly on the Wiki.
