eZ Publish supports the development of customized web applications. Typical applications range from a personal homepage to a multilingual corporate website, which include role-based multi-user access, e-commerce functions and online communities.[2]
The software is widely used in web applications of varying type and size worldwide, among them MIT (specifically the controller's office),[3] Vogue magazine, the US Navy DASN and the Swiss public broadcasting organisation Schweizer Fernsehen.[4]
eZ Publish is managed via a Web browser, and additional local software is not necessary. It also features a rich-text editor that allows formatting content similar to a word processor. This enables content editing and contribution without HTML skills. Content management can also be done through the eZ Publish frontend.
The software is provided for free, and may be used and modified according to the GPL. In addition, paid professional support is available with the eZ Publish Enterprise Edition. Furthermore, a commercial license is also available,[5] granting the right to use eZ Publish under license conditions different from the GPL.
To support its commercial operations, eZ Systems has a network of certified partner companies that perform application implementations. Currently there are approximately 200 partners worldwide.[6] The company itself employs about 90 people in Norway, Denmark, France, United States, Germany and Japan.[7] The eZ community, composed of programmers, designers and users can be found at the eZ Community site.
The eZ Publish range of features includes professional and secure development of web applications. Functional areas include content versioning, media library, role-based rights management, mobile development, sitemaps, search and printing.
Additionally, the system includes extensions, which contain individual functions. This allows for the upgrading of components while preserving compatibility with customized parts.
eZ Publish is written in PHP. The recommended web server is Apache.[8]
The database abstraction layer enables the use of most common databases, i.e. MySQL, PostgreSQL, Microsoft SQL Server, and Oracle, without changes to the core system, by using drivers.
The software is cluster-ready and enforces the separation of content and presentation via XML storage of all content.
eZ Publish features
[9] eZ Components is a library of standardized modules for speeding up application development. It includes functions for compressing binary files, optimizing performance through caching, connecting to several databases, debugging, RSS, generating graphs for analysis, converting images, supporting email and validating user input.[10]
In an effort to transition the development from a company-driven to a community-driven model, the whole source of the eZ Components were donated to the Apache Software Foundation, relicensed from the BSD to the Apache 2 license and renamed to Zeta Components. [11][12][13][14]
Extensions not available to download[15]
