The Foresite Project has released the foresite-toolkit.

Here's an excerpt from the announcement (footnotes removed):

The Foresite project is pleased to announce the initial code of two software libraries for constructing, parsing, manipulating and serialising OAI-ORE Resource Maps. These libraries are being written in Java and Python, and can be used generically to provide advanced functionality to OAI-ORE aware applications, and are compliant with the latest release (0.9) of the specification. The software is open source, released under a BSD licence, and is available from a Google Code repository . . . .

Foresite is a JISC funded project which aims to produce a demonstrator and test of the OAI-ORE standard by creating Resource Maps of journals and their contents held in JSTOR, and delivering them as ATOM documents via the SWORD interface to DSpace. DSpace will ingest these resource maps, and convert them into repository items which reference content which continues to reside in JSTOR. The Python library is being used to generate the resource maps from JSTOR and the Java library is being used to provide all the ingest, transformation and dissemination support required in DSpace.

Rob Sanderson at the University of Liverpool has established the OAI-ORE: Object Reuse and Exchange Wiki, which is now open for content contributions. A preliminary content structure has been set-up for users to populate.

The Open Archives Initiative has released the public beta of Object Reuse and Exchange Specifications.

Here's an excerpt from the press release:

Over the past eighteen months the Open Archives Initiative (OAI), in a project called Object Reuse and Exchange (OAI-ORE), has gathered international experts from the publishing, web, library, and eScience community to develop standards for the identification and description of aggregations of online information resources. These aggregations, sometimes called compound digital objects, may combine distributed resources with multiple media types including text, images, data, and video. The goal of these standards is to expose the rich content in these aggregations to applications that support authoring, deposit, exchange, visualization, reuse, and preservation. Although a motivating use case for the work is the changing nature of scholarship and scholarly communication, and the need for cyberinfrastructure to support that scholarship, the intent of the effort is to develop standards that generalize across all web-based information including the increasing popular social networks of “web 2.0”. The beta version of the OAI-ORE specifications and implementation documents are released to the public on June 2, 2008. These documents describe a data model to introduce aggregations as resources with URIs on the web. They also detail the machine-readable descriptions of aggregations expressed in the popular Atom syndication format, in RDF/XML, and RDFa.

The Open Archives Initiative's Object Reuse and Exchange project has released version 0.3 of the ORE Specification and User Guide.

JISC is funding two projects to do small-scale OAI-ORE tests:

TheOREM (Theses with ORE Metadata), at the University of Cambridge, aims to:

• Test the applicability of the ORE standard in a realistic scholarly setting—thesis description, submission and publication.
• Demonstrate the advantages of the ORE approach in complex object publication, by combining it with existing web-standards compliant technologies.
• Provide examples to fully exercise the ORE specifications in order to provide validation and future direction.

FORESITE (Functional Object Reuse and Exchange: Supporting Information Topology Experiments) will create Resource Map descriptions of JSTOR's holdings, and then ingest them into the DSpace institutional repository system via the SWORD protocol, creating external references back to the original files. The description work will be automated, and the system for achieving this implemented at the University of Liverpool. The SWORD protocol will be implemented within DSpace by HP Labs along with other extensions necessary.

For further information, see the FORESITE proposal, A Preview of the TheOREM Project, and the TheOREM proposal.

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).

The open source OAI4J software from the National Library of Sweden "can be used to harvest metadata from OAI-PMH compliant repositories. It can also be used to create new OAI-ORE Resource Maps from scratch, to parse existing ones and to serialize them to xml." You can download the client, which is written in Java, from SourceForge.
