Here's an excerpt:

In this paper the authors show an overview of Virtual Digital Mathematics Library in Japan (DML-JP), contents of which consist of metadata harvested from institutional repositories in Japan and digital repositories in the world. DML-JP is, in a sense, a subject specific repository which collaborate with various digital repositories. Beyond portal website, DML-JP provides subject-specific metadata through OAI-ORE. By the schema it is enabled that digital repositories can load the rich metadata which were added by mathematicians.

Aggregations of Web resources are increasingly important in scholarship as it adopts new methods that are data-centric, collaborative, and networked-based. The same notion of aggregations of resources is common to the mashed-up, socially networked information environment of Web 2.0. We present a mechanism to identify and describe aggregations of Web resources that has resulted from the Open Archives Initiative – Object Reuse and Exchange (OAI-ORE) project. The OAI-ORE specifications are based on the principles of the Architecture of the World Wide Web, the Semantic Web, and the Linked Data effort. Therefore, their incorporation into the cyberinfrastructure that supports eScholarship will ensure the integration of the products of scholarly research into the Data Web.

Here's an excerpt from the tool's page:

The IN Harmony Sheet Music Cataloging Tool is an open source tool developed by the Indiana University Digital Library Program with funding from the Institute of Museum and Library Services as part of the IN Harmony: Sheet Music From Indiana project. This tool has been designed to assist libraries, archives, museums, and individual collectors describe their sheet music collections in a robust and standards-based way. This is a production system of the Indiana University Digital Library Program and was used to catalog more than 10,000 pieces of sheet music for the IN Harmony project.

The tool collects descriptive metadata about sheet music and exports it in the MODS, simple Dublin Core, and OAI-PMH Static Repository formats.

(OAI-ORE) specifications provide a flexible set of mechanisms for transferring complex data objects between different systems. In order to serve as an exchange syntax, OAI-ORE must be able to support the import of information from localized data structures serving various communities of practice. In this paper, we examine the Metadata Encoding & Transmission Standard (METS) and the issues that arise when trying to map from a localized structural metadata schema into the OAI-ORE data model and serialization syntaxes.

Here's an excerpt:

In the digital age libraries are required to manage large numbers of diverse objects. One advantage of digital objects over fixed physical objects is the flexibility of ‘binding’ them into publications or other useful aggregated intellectual entities while retaining the ability to reuse them independently in other contexts. An emerging framework for managing flexible aggregations of digital objects is provided by the Open Archives Initiative (OAI) with its work on Object Reuse and Exchange (ORE). This paper will show how OAI-ORE is being used to manage content in digital repositories, in particular institutional repositories, and has the potential ultimately to transform the conception of digital repositories.

Here's the abstract:

Work in the Open Archives Initiative-Object Reuse and Exchange (OAI-ORE) focuses on an important aspect of infrastructure for eScience: the specification of the data model and a suite of implementation standards to identify and describe compound objects. These are objects that aggregate multiple sources of content including text, images, data, visualization tools, and the like. These aggregations are an essential product of eScience, and will become increasingly common in the age of data-driven scholarship. The OAI-ORE specifications conform to the core concepts of the Web architecture and the semantic Web, ensuring that applications that use them will integrate well into the general Web environment.

Here's an excerpt from the press release:

These standards provide the foundation for applications and services that can visualize, preserve, transfer, summarize, and improve access to the aggregations that people use in their daily Web interaction: including multiple page Web documents, multiple format documents in institutional repositories, scholarly data sets, and online photo and music collections. The OAI-ORE standards leverage the core Web architecture and concepts emerging from related efforts including the semantic web, linked data, and Atom syndication. As a result, they integrate both with the emerging machine-readable web, Web 2.0, and the future evolution of networked information. . . .

The documents in the release 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.

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.

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.

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.
