The latest release of Fedora is ready for integration into large repository systems

Ithaca, NY Today the Fedora Committers Group and the DuraSpace organization announced the release of Fedora 3.5. This release of Fedora, the robust framework for building digital repositories, focuses on several "under the hood" changes that improve Fedora's ability to be integrated and tested as part of larger repository systems. Version 3.5, led by Aaron Birkland, Developer, Cornell University, also sets the stage for a full move to Spring-based pluggability ( and configuration. Several of the most popular issues are addressed in this release, including dropping the requirement to use DBXML if you elect to use FeSL for policy enforcement.

• Spring-based configuration. Fedora has adopted Spring as a means of configuring its internal components. This move to a modern, enterprise-grade framework offers greater flexibility for integrating repository components, and allows Fedora to more easily adapt to challenging deployment environments. While fedora.fcfg is considered deprecated as of this release, due to time constraints some module configuration has not yet been moved out of fedora.fcfg and into native spring xml. See also Spring Configuration in the documentation.
• Standard WAR file distribution. Fedora runtime configuration has moved entirely outside of the WAR file, allowing a single standardized war file to be included in each release. This allows bugfix releases to be distributed and applied in a much simpler fashion than before: merely replace the old WAR file with the updated one.
• FeSL policy enforcement improvements. Numerous enhancements have been made to FeSL authZ. Notably, the requirement of installing dbxml has been removed. This had been a barrier to FeSL testing and adoption. With the various improvements in FeSL authZ, we consider this feature "beta" and encourage users of Fedora to give it a try and provide feedback.
• FEDORA_HOME environment variable no longer required to run fedora server. Outside of running commandline utilities, FEDORA_HOME is now ignored, and has been completely replaced with more flexible means of specifying the location of the fedora home directory.
• JSON support for RISearch Resource index searches now support JSON, allowing greater ease of use with javascript clients.
• DC datastream fixes. The DC datastream, with contains information needed for the internal functioning of Fedora, is now more robust. If a user inadvertently removes the necessary dc:identifier fields, this will be automatically corrected.
• Build and testing improvements. Numerous testing and development improvements are part of 3.5. Perhaps most notably, deployment and running of a live Fedora instance can now be managed automatically as part of a standard maven build.

Fedora is an open source project of the DuraSpace organization.
