New Fedora 3.0 Beta Available

Latest Release of Fedora Repository Software

The 12th release of the Fedora repository software is now available and is the first version of featuring a Content Model Architecture (CMA). UPEI has been working with Fedora 2 for almost a full year now and we are very much looking forward to 3.0 - highly recommended for institutions looking for a robust and flexible repository solution. From the press release:

Dan Davis, Chief Software Architect, Fedora Commons, 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.

Some changes in the Beta code include:

• Content Model Architecture - Provides a model-driven approach for persisting and delivering the essential characteristics of digital content in Fedora
• API-M LITE - An experimental interface for the creating, modifying, and managing digital objects using a Web interface in a REST style
• Mulgara Support - Fedora now supports the Mulgara Semantic Triplestore replacing Kowari
• Migration Utility - Provides an update utility to convert existing collections for Content Model Architecture compatibility
• Relational Index Simplification - The Fedora schema was simplified making changes easier with having to reload the database
• Dynamic Behaviors - Object may added or removed dynamically from the system moving system checks into runtime errors
• Error Reporting - Provides improved runtime error details
• Owner as a CSV String - Enables using a CSV string as ownerID and in XACML policies
• Java 6 Compatibility - Fedora may be optionally compiled using Java 6

And some promised for the final release of 3.0 include:

• Simple JMS Messaging - Integrates JMS messaging for sending notification of important events
• Administrative Client - Revised to support Content Model Architecture enhancements
• Message Update for GSearch - Provides a reference implementation for using JMS notifications to update search engines
