What changed because of the switch from TWiki to foswiki

---

Introduction

In June 2016, 52°North switch from TWiki to foswiki. This results in some changes in naming things. This topic collects all required information.

Terminology changes

As part of the first Foswiki product release, various topics and terms were changed to avoid using the TWiki brand name and to more accurately reflect their purpose, including the following:

• The TWiki web is now called System, as it contains configuration information for the entire Foswiki installation. The TWikiCompatibilityPlugin provides backwards compatible support for references to the TWiki web, in order to facilitate migrations from TWiki to Foswiki.
• The %TWIKIWEB% and %MAINWEB% variables are now called %SYSTEMWEB% and %USERSWEB%
• Topics in the Foswiki distribution have been renamed to eliminate the TWiki word and to make the titles more readable (for example, Plugins, Skins, and so forth).
• All templates, CSS and Javascript names have been changed from twikiXxxxx to foswikiXxxxx
• Key terminology changes:
