Tutorial 5B: Object Reuse and Exchange: The OAI-ORE Framework
Half Day

This tutorial will give an overview and a practical introduction to the OAI Object Reuse and Exchange (OAI-ORE) framework and specifications [1]. The OAI-ORE framework recasts the repository-centric notion of a digital object as a bounded aggregation of Web resources. These aggregations are described by Resource Maps. The tutorial will motivate the approach with several use cases including description of scholarly publications, complex objects in repositories, eScience objects, and aggregations from common web applications such as Flickr.  The tutorial will describe the OAI-ORE data model and how Resource Maps are serialized. Focus will be on the the Atom serialization format, as this is proposed as the standard format for maximum interoperability. Issues of discoverability will be discussed and the tutorial will conclude with a summary of tools currently available to assist with OAI-ORE development and use.

Learning Objectives:

  • Understanding of the motivations for OAI-ORE specifications
  • Familiarity with the OAI-ORE data model and concepts
  • Understanding of the use of Atom as a serialization format and alternative serializations
  • Understanding of integration with the Web, discoverability issues
  • Familiarity with currently available tools.

Target Audience:
The intended audience includes technologists and managers with some technical knowledge. The tutorial will assume familiarity with notions of digital objects, repositories, identifiers, the Web, and XML.

Level of Experience: 
No prior experience with OAI-ORE, OAI-PMH, Atom or the Semantic Web is expected.

Simeon Warner is the manager and a developer of the arXiv e-print archive (http://arxiv.org/), and has worked with the Open Archives Initiative (OAI) since its inception. He was one of the editors of the OAI protocol for metadata harvesting (OAI-PMH) specification and currently is working on the OAI Object Reuse and Exchange effort (OAI-ORE). He is a Research Associate in Computing and Information Science at Cornell University and a member of the Digital Library and Information Technologies group of the Cornell University Library.

Herbert Van de Sompel graduated in Mathematics and Computer Science at Ghent University, and in 2000, obtained a Ph.D. there. For many years, he was Head of Library Automation at Ghent University. After having left Ghent in 2000, he has been Visiting Professor in Computer Science at Cornell University, and Director of e-Strategy and Programmes at the British Library. Currently, he is the team leader of the Digital Library Research and Prototyping Team at the Research Library of the Los Alamos National Laboratory. Herbert has played a major role in creating the Open Archives Protocol for Metadata Harvesting, the OpenURL Framework for Context-Sensitive Services, the 2 SFX linking server, and info URI. He currently focuses his attention on the Open Archives Initiative Object Re-Use & Exchange effort (ORE) and on the MESUR project that researches usage-based indicators of scholarly impact.

Carl Lagoze is a Senior Research Associate in Computing and Information Science at Cornell. In this role he teaches, directs graduate students, and participates in research funded by NSF, the Andrew W. Mellon Foundation, and Microsoft. His primary research interests include architecture and protocols for distributed information environments, automatic organization of web information, and new environments for scholarly communication. In research collaborations with colleagues at Cornell and elsewhere he has played a major role in the Open Archives Initiative Project forMetadata Harvesting and Object Reuse and Exchange, the Dienst/NCSTRL architecture and protocol for distributed digital libraries, the ABC metadata ontology, and the Fedora Open Source Repository System. He has served on a number of boards and committees including the Program Committees of U.S., European, and Asian Digital Library Conferences, the Advisory Committee of the National Virtual Observatory, the External Advisory Board of the Los Alamos Research Library, and the National Advisory Board of the University of Texas Utopia Project.
