Content management is no exception to this shift toward open source tools. Gregor J. Rothfuss writes about the current state of open source content management and identifies the important applications that will continue to evolve in the next 10 years. Rothfuss describes the progress on a standard for repository-based content (JSR 170) and the fascinating advances driven by software for online collaboration used by open source projects. Finally, he provides a snapshot of the leading open source CMSs – Apache Lenya, Midgard, OpenCms, Plone, and TYPO3. Based on the concepts and applications Rothfuss describes, open source projects will continue to challenge the market position of the traditional vendors by promoting open standards and innovation.
