An Update from the OAI Herbert Van de Sompel Technical Staff Member, Research Library Los Alamos National Laboratory Carl Lagoze Senior Research Associate, Information Science Program Director of Technology, National Science Digital Library Program Cornell University Simeon Warner Research Associate Cornell University Michael Lloyd Nelson Assistant Professor Old Dominion University This project briefing will outline the ongoing efforts and future plans of the Open Archives Initiative. Topics that will be covered include: • OAI-Rights: An international Technical Committee was formed, charged with specifying how rights expressions can be conveyed in the OAI-PMH Framework. The first deliverable of the Committee is a specification pertaining to conveying rights about metadata. An overview of this specification will be presented. A future effort will look into conveying rights pertaining to resources about which OAI-PMH repositories expose metadata. • Harvesting content using the OAI-PMH: Use-cases are emerging in which an interoperable approach for harvesting content (not only metadata) has become essential. These include the mirroring of content-repositories for preservation purposes and the creation of services based on the content itself. An insight will be given as to how this interoperability requirement can be addressed within the boundaries of the OAI-PMH. Also, an overview will be given of the issues that need to be addressed in order for the proposed solution to be deployable as a platform for interoperability. • mod_oai: The mod_oai project has set out to bring the power of selective/incremental harvesting, as provided by the OAI-PMH, to off-the-shelf Apache Web servers. Anticipated benefits include an optimization of Web crawling activities with respect to both performance and coverage. An overview and demonstration of the proposed solution and its benefits will be presented. PowerPoint Presentation Session Handout (PDF) http://www.openarchives.org Herbert Van de Sompel, et al.
