TYPO3 is a free and open source content management system as well as a Model–view–controller (MVC) Web Application Development framework written in PHP. It is released under the GNU General Public License. It can run on Apache or IIS on top of Linux, Microsoft Windows, OS/2 or Mac OS X.
TYPO3 was initially authored by Kasper Skårhøj. It is now developed by two teams. The maintenance tree, version 4.x, team leader is Michael Stucki. The development tree, version 5.x, team leader is Robert Lemke.
Many of TYPO3's pluggable extensions have been written by third party developers.
Along with a set of ready-made interfaces, functions and modules TYPO3 has a large repository of extensions, allowing flexibility and extendibility. More than 4000 extensions are available for download under the GNU General Public License from a repository called the TYPO3 Extension Repository, or TER.
The system is based on templates. People can choose an existing template and change features such as logo, colors, and fonts, or they can construct their own templates using a configuration language called TypoScript. In this simple notation, a large object tree structure of information is created with placeholders for data from the database to fill in. Preprogrammed objects are configured by changing or adding values or features. This object tree structure is saved in a text file. Various editors are available to change the content in a structured way. The PHP generator uses this data structure to drive the generation of the content. Besides conditions, TypoScript has no other control structures; if real processing must be performed, it is handed to a PHP function. The top level object is the PAGE object. There are various types of MENU objects.
Syntax of TypoScript
The basic syntax is:
[objectpath].[attribute] [operator] [value]
- = assignment of a value
- < copy a whole object
- =< insert a reference
- > remove object
The content is mainly stored in two tables: one table called pages and another called tt_content, which holds the elements contained in a page. Every page object has a unique identification key (uid) and is linked to a parent page. Thus, the pages are organized in tree form, allowing the system to easily generate menus and site maps.
One key feature of TYPO3 is that it has a flexible application programming interface which enables independent developers to provide extra functionality. Modules using this API are called "extensions" and many developers provide their extensions in a publicly available repository on the TYPO3 developer portal.
TemplaVoila is an alternative template engine extension for TYPO3. A graphical mapping tool for creating templates is included, an alternative page module, the ability to create flexible content elements and an API for developers. New content element types can be created without programming.
TemplaVoila facilitates more flexibility for maintaining web pages than TYPO3's standard templating, while making it possible to enforce a strict corporate design and allowing editors to work with content more intuitively. On the other hand, it is also slower than the standard templating.
