Wiki software

"Wiki" is an Hawaiian word meaning "fast" or "quick". The term wiki is now applied to software that facilitates development of a website that can be updated by many editors working collaboratively.

Mediawiki, the software platform underlying Wikipedia and TS Wiki, employs a simplified markup language called "wikitext", and allows some elements of HTML as well.

A pioneer of information technology, Vanevaar Bush, foresaw something like a wiki in July, 1945:

Consider a future device for individual use, which is a sort of mechanized private file and library. It needs a name, and to coin one at random, memex will do. A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory. Wholly new forms of encyclopedias will appear, ready-made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified.<re></ref>
