DESCRIPTION
The Horde project offers a complete web based groupware suite coded in PHP. The center of the application is the webmailer "Imp". Born about 13 years ago it has been one of the first existing webmail solutions. It is no wonder that by today it provides millions of users with web based access to their e-mail. The next major release of the groupware suite - Horde 4 - was made available in April 2011 and offers a dynamic AJAX based e-mail as well as calendar component. Applications for task, contact and note management are included as well. There is broad support for mobile devices - ActiveSync, SyncML, mobile front ends for iPad, iPhone, Android to name just a few. This huge feature set common to modern groupware suites does require a solid backbone of small modules delivering various functionality to speak IMAP, SQL, LDAP, MIME, iCal, iTip or to handle dates, authentication, caching, sessions etc. In other words: a framework underlying the applications visible to the user. The Horde framework existed for years and has grown in time to more than a hundred distinct modules. With Horde 4 this framework has now been published component by component for the very first time. Each module is now available as a separate PEAR package with clearly defined dependencies. Thus developers can now download and use small segments of the Horde code into their own projects without having to deal with the complexities of the whole application stack. The major advantage the Horde framework has when compared with similar frameworks: the development has been driven by the needs of real world applications that are being used by millions of users on a daily basis. The Horde code quality always had high standards but Horde 4 has been a major step in that area as well. The components have test suites which are now automatically validated by a continuous integration server based on Jenkins. This also includes code style analysis and various code metrics common to PHP based Jenkins setups. The talk will touch main features of the Horde 4 groupware suite release but primarily focus on the Horde 4 framework and the huge set of powerful PHP libraries which are now available to the PHP community.

Summary
Horde 4 PHP framework
The Horde 4 PHP framework is independent of the Hordeapplications.
The Horde 4 architecture is extremely modular.
Horde Applications
Horde can be adapted to the workflow instead of the other wayaround.
The groupware can be embedded into many different types ofinfrastructure.
Simply the most flexible web groupware system around.
