The Fedora Commons has released version 2.2.2 of Fedora, which fixes 2.2.1 bugs and enhances the system's journaling and policy enforcement modules. (Version 3.0 Beta 1 is also available for testing.)

Oskar Grenholm of the National Library of Sweden has released oreprovider, an open-source Java application that "will let you disseminate digital objects stored in a Fedora repository as OAI-ORE Resource Maps."

In the announcement, he says:

The idea behind it all is that you have a Java web application (oreprovider.war) that, on the fly, will generate Resource Maps serialized as Atom feeds (using OAI4J) for objects in Fedora. All you have to do in Fedora is to add information in RELS-EXT what datastreams belongs to which Resource Map (exactly how to do this can be seen at the projects web page).

Fedora Commons has launched HatCheck, a quarterly newsletter about the popular Fedora digital repository software.

Articles in the first issue include "Engineering Punchlist" and "Welcome to HatCheck: A Place to 'Check Your Hat' and Learn More About Fedora Commons."

The DRAMA (Digital Repository Authorization Middleware Architecture) team has released version 1.2.1 of Muradora.

Here's an excerpt from the Muradora home page that describes Muradora:

Muradora is an easy to use repository application that supports federated identity (via Shibboleth authentication) and flexible authorization (using XACML). Muradora leverages the modularity, flexibility and scalability of the well-known Fedora repository.

Muradora's unique vision is one where Fedora forms the core back-end repository, while different front-end applications (such as portlets or standalone web interfaces) can all talk to the same instance of Fedora, and yet maintain a consistent approach to access control.

Statsbiblioteket is developing Summa, a federated search system.

Birte Christensen-Dalsgaard, Director of Development, discusses Summa and other topics in a new podcast (CNI Podcast: An Interview with Birte Christensen-Dalsgaard, Director of Development at the State and University Library, Denmark).

Here's an excerpt from the podcast abstract:

Summa is an open source system implementing modular, service-based architecture. It is based on the fundamental idea "free the content from the proprietary library systems," where the discovery layer is separated from the business layer. In doing so, any Internet technology can be used without the limitations traditionally set by proprietary library systems, and there is the flexibility to integrate or to be integrated into other systems. A first version of a Fedora—Summa integration has been developed.

A white paper is available that examines the system in more detail.

JISC has released SHERPA DP: Final Report of the SHERPA DP Project.

Here's an excerpt from the "Executive Summary":

The SHERPA DP project (2005–2007) investigated the preservation of digital resources stored by institutional repositories participating in the SHERPA project. An emphasis was placed on the preservation of e-prints—research papers stored in an electronic format, with some support for other types of content, such as electronic theses and dissertations.

The project began with an investigation of the method that institutional repositories, as Content Providers, may interact with Service Providers. The resulting model, framed around the OAIS, established a Co-operating archive relationship, in which data and metadata is transferred into a preservation repository subsequent to it being made available. . . .

The Arts & Humanities Data Service produced a demonstrator of a Preservation Service, to investigate the operation of the preservation service and accepted responsibility for the preservation of the digital objects for a three-year period (two years of project funding, plus one year).

The most notable development of the Preservation Service demonstrator was the creation of a reusable service framework that allows the integration of a disparate collection of software tools and standards. The project adopted Fedora as the basis for the preservation repository and built a technical infrastructure necessary to harvest metadata, transfer data, and perform relevant preservation activities. Appropriate software tools and standards were selected, including JHOVE and DROID as software tools to validate data objects; METS as a packaging standard; and PREMIS as a basis on which to create preservation metadata. . . .

A number of requirements were identified that were essential for establishing a disaggregated service for preservation, most notably some method of interoperating with partner institutions and he establishment of appropriate preservation policies. . . . In its role as a Preservation Service, the AHDS developed a repository-independent framework to support the EPrints and DSpace-based repositories, using OAI-PMH as common method of connecting to partner institutions and extracting digital objects.

JISC has released Machine Services for Metadata Discovery and Aggregation—metadata+.

Here's an excerpt from the Executive Summary:

The main aim of the project is to develop an interoperability demonstrator to explore the technical aspects of providing a service-oriented infrastructure to facilitate metadata discovery and aggregation. The project developed a test bed that exposes metadata through standard search and linking protocols. Metadata mapping work was undertaken to enable the test bed to provide search response in multiple metadata schemas that are widely used in digital library and e-learning.

The core of the test bed consists of an open source digital repository—Fedora. Off-the-shelf, the repository provides web services for metadata searching and substantial content management and security features particularly suitable for real-life use scenarios. Since the search protocol considered in this project requires additional features that are not available from the repository, modifications to the repository source code were made. The modifications also involve incorporating the metadata mapping requirement such that search responses from different metadata formats can be facilitated.

A basic demonstrator (project website) has been created to exemplify how the search protocol can be used for discovering and aggregating metadata, as well as presenting them in coherent formats relevant to the intended presentation contexts. The metadata sources include publisher and digital libraries providing both bibliographic and user-generated (enrichment) metadata such as reviews and recommendations. In addition, the project demonstrated a novel use of the search protocol to dynamically create e-learning content packages, digital library metadata collection and news feeds.

Several digital libraries initiatives have evaluated the test bed infrastructure for real use scenarios. These libraries are an extended form of the test bed demonstrator and provide relevant facilities such metadata wiki (editor) and annotation services for gauging enrichment metadata (review, rating and recommendation) from users. They will continue the objectives of this project particularly on improving the test bed infrastructure and exploring the aggregated use of enrichment metadata, to enable the academic and research user communities to add values to bibliographic metadata from the publishers and libraries communities.
