Users have built TWiki applications<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> that include call center status boards, <a href="/facts/Task_list/g2kdl0C8">to-do lists</a>, <a href="/facts/Inventory/vSBu0d9r">inventory</a> systems, <a href="/facts/Employee_handbook/7daBBFv6">employee handbooks</a>, <a href="/facts/Bug_tracking_system/xCdIz6Kx">bug trackers</a>, <a href="/facts/Blog/bb6awu2X">blog</a> applications, discussion forums, status reports with rollups and more. </p> <h3>User interface</h3> <p>The interface of TWiki is completely skinnable in templates, themes and (per user) <a href="/facts/Cascading_Style_Sheets/tA90XBQo">CSS</a>. It includes support for <a href="/facts/Internationalization/QpnqEC7H">internationalization</a> ('<a href="/facts/I18N/IGkl9VBM">I18N</a>'), 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.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p> <h2 id="twiki-deployment">TWiki deployment</h2> <p>TWiki is primarily used at the workplace as a <a href="/facts/Corporate_wiki/zNRxq6GV">corporate wiki</a><a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> to coordinate team activities, track projects, implement <a href="/facts/Workflow/Ig8zvxF2">workflows</a><a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> and as an <a href="/facts/Intranet_Wiki/zNRxq6GV">Intranet Wiki</a>. The TWiki community estimates 40,000 corporate wiki sites as of March 2007, and 20,000 public TWiki sites.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> </p><p>TWiki customers include <a href="/facts/Fortune_500/BLeHWymz">Fortune 500</a> such as <a href="/facts/Disney/R8kCbAVc">Disney</a>, <a href="/facts/Motorola/ztqczx68">Motorola</a>, <a href="/facts/Nokia/bCleFoF4">Nokia</a>, <a href="/facts/NYU/4UnIkThy">NYU</a>, <a href="/facts/Oracle_Corporation/0z14FygH">Oracle Corporation</a> and <a href="/facts/Yahoo!/nKhTaV3M">Yahoo!</a>, as well as <a href="/facts/Small_and_medium_enterprise/86CC7BvV">small and medium enterprises</a>,<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> such as <a href="/facts/ARM_Holdings/jqqppj7b">ARM Holdings</a>[<i>dead link</i>]<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> and <a href="/facts/DHL_Express/UoHyydxd">DHL</a>.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> TWiki has also been used to create collaborative internet sites, such as the <a href="/facts/City_of_Melbourne/V0PEheLy">City of Melbourne</a>'s <i>FutureMelbourne</i> wiki where citizens can collaborate on the future plan.<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> </p> <h2 id="realization">Realization</h2> <p>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 <a href="/facts/Revision_Control_System/9rHoEV5Y">RCS</a>. RCS is optional since an all-Perl version control system is provided. </p><p>TWiki scales reasonably well even though it uses plain text files and no <a href="/facts/Relational_database/pEKGmJLy">relational database</a> to store page data. Many corporate TWiki installations have several hundred thousand pages and tens of thousands of users. <a href="/facts/Load_balancing_(computing)/jddk6ang">Load balancing</a> and caching can be used to improve performance on high traffic sites.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> </p><p>TWiki has database features built into the engine. A TWiki Form<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a> 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<a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a> with a SQL-like query<a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a> can be embedded into a page to construct dynamic presentation of data from multiple pages. This allows for building <a href="/facts/Wiki_application/zNRxq6GV">wiki applications</a> and constitutes the TWiki's notion of a <a href="/facts/Structured_wiki/zNRxq6GV">structured wiki</a>. </p> <h2 id="forks-of-twiki">Forks of TWiki</h2> <p><a href="/facts/Fork_(software_development)/D6khxhpr">Forks</a> of TWiki include: </p> <ul><li>2001: Spinner Wiki (abandoned)</li> <li>2008: <a href="/facts/Foswiki/F242sco8">Foswiki</a>, launched in October 2008 when a dispute about the future guidance of the project could not be settled,<a class="footnote-ref" id="fnref:22" href="#fn:22"><sup>22</sup></a><a class="footnote-ref" id="fnref:23" href="#fn:23"><sup>23</sup></a> resulting in the departure of much of the TWiki community including the core developer team<a class="footnote-ref" id="fnref:24" href="#fn:24"><sup>24</sup></a></li></ul> <h2 id="gallery">Gallery</h2> <h2 id="see-also">See also</h2> <ul> <li>Free and open-source software portal</li></ul> <ul><li><a href="/facts/Comparison_of_wiki_software/ymlSd25l">Comparison of wiki software</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://twiki.org/">TWiki.org - Open source community site</a></li> <li><a href="http://twiki.org/cgi-bin/view/Codev/ComparisonOfMediaWikiToTWiki">Comparison between TWiki and MediaWiki</a> <a href="https://web.archive.org/web/20080517072329/http://twiki.org/cgi-bin/view/Codev/ComparisonOfMediaWikiToTWiki">Archived</a> 17 May 2008 at the <a href="/facts/Wayback_Machine/nmQ3a6JC">Wayback Machine</a></li> <li><a href="https://web.archive.org/web/20130412040709/http://www.twiki.net/">TWIKI.NET - company providing commercial installation, support and hosting solutions for TWiki</a></li> <li><a href="https://www.wikimatrix.org/show/TWiki">WikiMatrix description of TWiki</a></li> <li><a href="http://foswiki.org/">Foswiki.org - The Free and Open Source Wiki site</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"Everything You Need To Know To Get Started With Content Management Systems".
