Wiki engine evolution tree

Wiki engine evolution tree — the evolution tree in this article below shows roughly how various wiki engine (wiki software) developments are (or were) related and inter-related. For a full list of wiki engines we have indexed here on WikiIndex, see category: Wiki engine.

The evolution tree is a subjective approach to a classification of wiki engines according to their origins; where the original programmer (or founder) of the wiki engine got the idea of deriving (or forking) a new wiki engine from an existing wiki engine. Specifically: this is supposed to be a tree of the evolution of wiki engines (not wiki forums or wiki sites; just wiki engines only). It is supposed to show where a wiki engine was derived from. Of course, this can be very subjective, and be subject to interpretation and opinion. Nevertheless, it is hoped this page will provide food for thought on the history of wiki software.

Page format

Please try to list information using the following schema (items in bold are strongly preferred, though only the engine itself should be displayed in bold), using full wikilinks where possible (red links are acceptable):

wiki engine name — year the development of the wiki engine started; founding author/programmer; programming language (original/primary); its relation to any existing wiki engines; project or community the engine was originally made for [if any]; notable and / or new features;

by using (the leading hash # generates the auto-numbering):

#'''[[:Category:Engine Name|Engine Name]]''' — year; author / founder; prog lang; relation; original use; other comment;
