The Fedora Commons has released the second beta version of Fedora 3.0.

Here's an excerpt from the announcement:

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 Fedora CMA plays a central role in the Fedora architecture, in many ways forming the over-arching conceptual framework for future development of Fedora Repositories.

Like a well-thumbed book on a shelf, digital content is stored with the expectation that intellectual works will be the same each time they are accessed, whether the content was put away yesterday, or many years ago. Fedora is a simple, flexible and evolvable approach to delivering and sharing the "essential characteristics" of enduring digital content. Librarians, archivists, records managers, media producers, authors and publishers use patterns of expression formats such as books, journals, articles, collections to convey the essential characteristics of content. The capabilities of digital tools combined with essential characteristics of digital works result in well-understood patterns of expression for different types of content models.

The software engineering community also utilizes patterns of expression for the development of complex computer systems. The same concepts that satisfy agile IT infrastructures can help provide solutions for creating, accessing and preserving content. The Fedora CMA builds on the Fedora architecture-downloaded more than 18,000 times in the last 12 months—to simplify use while unlocking potential.

Dan Davis explains the CMA in the context of Fedora 3.0, "It's a hybrid. The Fedora CMA handles content models that are used by publishers and others, and is also a computer model that describes an information representation and processing architecture." By combining these viewpoints, Fedora CMA has the potential to provide a way to build an interoperable repository for integrated information access within organizations and to provide durable access to our intellectual works.
