OAI: What happened since Summer 2000

• End of Summer 2000 – Not only e-prints

• research library community• publishers, librarians, scholars

– Digital Library Federation and Coalition of Netwoked Information decided to support OAI

– Set up of a steerling and a technical committee– Revise interoperability specifications to allow

adoption beyond preprints

OAI: What happened since Summer 2000

• November 2000-January 2001: Alpha test of specifications:

• arXiv -- Los Alamos • NACA -- NASA• CogPrints -- U Southampton• ETD -- Virginia Tech• Thesis & Dissertations from WorldCat -- OCLC• American Memory -- Library of Congress

OAI: What happened since Summer 2000

• Alpha test of specifications (cont.):

• HeinOnline law journals -- Cornell U • TEI-lite collection -- U Tennessee• STM publisher metadata -- U Illinois• Resource Disovery Network -- UKOLN• Open Language Archives -- U Pennsylvania• Open Video Project -- U Northern Carolina• CIMI

OAI: What happened since Summer 2000

• January 2001– Released Version 1.0 of the OAI protocol

OAI – Cyclades: What happened since summer 2000

• October 2000: Cornell submitted proposal for Prism supplement funding– Interoperabiliy Architecture– Collection Service Architecture

• December 2000: Cornell submitted a proposal under the NSF – EU joint DL agreement – Collection level metadata– Context sensitive extended services

Why Cyclades is interesting for the OAI?

• Experimentation and evaluation of the low barrier interoperability– Harvesting– Archive description– Data description

• Which services can be implemented with the current level of interoperability agreements?

Why Cyclades is interesting for the OAI?

• What improvements will be possible by introducing appropriate controlled extensions?

• Which are the limitations that cannot be overcome?

• First example of set of interoperable archive services

Establishing assumptions

• Will Cyclades harvest all the OAI registered archives or a subset of them (e.g. e-print)?• Do we require DC mandatory fields (e.g. abstract)?• Do we need specific archive descriptions?

Personal view: Establish minimal initial assumptions, see how far we can go with them, and possibly to revise them later
