TWiki
Template:Short description Template:For Template:Use dmy dates Template:How-to Template:Infobox software TWiki is a Perl-based structured wiki application,<ref>Template:Cite news</ref> typically used to run a collaboration platform, knowledge or document management system, a knowledge base, or team portal. Users can create wiki pages using the TWiki Markup Language, and developers can extend wiki application functionality with plugins.
The TWiki project was founded by Peter Thoeny in 1998 as an open-source wiki-based application platform. In October 2008, the company TWiki.net, created by Thoeny, assumed full control over the TWiki project<ref name="cnet">Template:Cite web</ref> while much of the developer community<ref name="devcommunity">Template:Cite web</ref><ref name="Get-the-facts">Template:Cite web</ref> forked off to join the Foswiki project.<ref>Template:Cite web</ref>

TWiki extensions
TWiki has a plugin API that has spawned over 300 extensions<ref>Template:Cite web</ref> to link into databases, create charts, tags, sort tables, write spreadsheets, create image gallery and slideshows, make drawings, write blogs, plot graphs, interface to many different authentication schemes, track Extreme Programming projects and so on.
TWiki application platform
TWiki as a structured wiki provides database-like manipulation of fields stored on pages,<ref name="TWiki Forms">Template:Cite web</ref> and offers a SQL-like query language to embed reports in wiki pages.<ref>SEARCH variable Template:Webarchive, formatted search Template:Webarchive, SQL-like query search Template:Webarchive</ref>
Wiki applications are also called situational applications because they are created ad hoc by the users for very specific needs. Users have built TWiki applications<ref>Template:Cite web</ref> that include call center status boards, to-do lists, inventory systems, employee handbooks, bug trackers, blog applications, discussion forums, status reports with rollups and more.
User interface
The interface of TWiki is completely skinnable in templates, themes and (per user) CSS. It includes support for internationalization ('I18N'), with support for multiple character sets, UTF-8 URLs, and the user interface has been translated into Chinese, Czech, Danish, Dutch, French, German, Italian, Japanese, Polish, Portuguese, Russian, Spanish and Swedish.<ref name="UserInterfaceLocalisation">Template:Cite web</ref>
TWiki deployment
TWiki is primarily used at the workplace as a corporate wiki<ref>Paper on corporate wiki users Template:Webarchive (slides Template:Webarchive)</ref> to coordinate team activities, track projects, implement workflows<ref>"The wiki as online conveyor belt" section in BusinessWeek article Make Some Noise - How web 2.0 tools can help you communicate with customers more effectively Template:Webarchive</ref> and as an Intranet Wiki. The TWiki community estimates 40,000 corporate wiki sites as of March 2007, and 20,000 public TWiki sites.<ref>Template:Cite web</ref>
TWiki customers include Fortune 500 such as Disney, Motorola, Nokia, NYU, Oracle Corporation and Yahoo!, as well as small and medium enterprises,<ref>Template:Cite web</ref> such as ARM HoldingsTemplate:Dead link<ref> Template:Cite web</ref> and DHL.<ref>Template:Cite web</ref> TWiki has also been used to create collaborative internet sites, such as the City of Melbourne's FutureMelbourne wiki where citizens can collaborate on the future plan.<ref>Template:Cite web</ref>
Realization
TWiki is implemented in Perl. Wiki pages are stored in plain text files. Everything, including meta such as access control settings, are version controlled using RCS. RCS is optional since an all-Perl version control system is provided.
TWiki scales reasonably well even though it uses plain text files and no relational database to store page data. Many corporate TWiki installations have several hundred thousand pages and tens of thousands of users. Load balancing and caching can be used to improve performance on high traffic sites.<ref>Template:Cite web</ref>
TWiki has database features built into the engine. A TWiki Form<ref name="TWiki Forms"/> is attached to a page as meta data. This represents a database record. A set of pages that share the same type of form build a database table. A formatted search<ref>Template:Cite web</ref> with a SQL-like query<ref>Template:Cite web</ref> can be embedded into a page to construct dynamic presentation of data from multiple pages. This allows for building wiki applications and constitutes the TWiki's notion of a structured wiki.
Forks of TWiki
Forks of TWiki include:
- 2001: Spinner Wiki (abandoned)
- 2008: Foswiki, launched in October 2008 when a dispute about the future guidance of the project could not be settled,<ref>Template:Cite web</ref><ref name="Foswiki-why">
Template:Cite web</ref> resulting in the departure of much of the TWiki community including the core developer team<ref name=Get-the-facts />
