Major Upgrade: Fedora 3.0 Released

Fedora Commons has released version 3.0 Fedora, which "completes all general release features."

Here's an excerpt from the press release:

Dan Davis, Chief Software Architect, Fedora Commons, explained, "We are pleased to offer a Fedora 3.0 that is a foundational step towards a model-driven content architecture." He went on to say, "Users will find it simpler to maintain and operate their repositories with version 3.0-it's more scalable and fits better into the Web."

Fedora 3.0 features the Content Model Architecture (CMA), an integrated structure for persisting and delivering the essential characteristics of digital objects in Fedora. The software is available at http://www.fedora-commons.org/ and at http://sourceforge.net/projects/fedora-commons. The Fedora CMA plays a central role in the Fedora architecture, in many ways forms the over-arching conceptual framework for future development of Fedora Repositories. Fedora 3.0 features include:
