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.
