the OAI: overview and historical context OAI Open Meeting – Washington DC – January 23 rd 2001 Herbert Van de Sompel & Carl Lagoze Cornell University -- Computer Science

herbert van de sompel The Open Archives Initiative has been set up to create a forum to discuss and solve matters of interoperability between preprint solutions, as a way to promote their global acceptance. Paul Ginsparg, Rick Luce & Herbert Van de Sompel OAI origin herbert van de sompel

The Open Archives Initiative develops and promotes interoperability standards that aim to facilitate the efficient dissemination of content. new OAI mission statement herbert van de sompel

The Open Archives Initiative has its roots in an effort to enhance access to e-print archives as a means of increasing the availability of scholarly communication. Continued support of this work remains a cornerstone of the Open Archives program. new OAI mission statement herbert van de sompel

The fundamental technological framework and standards that are developing to support this work are, however, independent of the both the type of content offered and the economic mechanisms surrounding that content, and promise to have much broader relevance in opening up access to a range of digital materials.
