Open Archives Initiative (OAI)
• Interoperability and Aggregation Standards for dissemination of Metadata– http://www.openarchives.org– Based on HTTP and XML Standards– Minimum Metadata required is Dublin Core
http://dublincore.org.– Other Metadata Schemas Allowed
• Various Services can be built on top of OAI– Harvesting– Search and Discovery, Linking
• Model for Scholarly Communication and Construction of Digital Libraries
OAI is a tool• All about moving metadata (not data) around.• A building block, useable by many
communities – supports new models of scholarly communication.
• Facilitates and enables centralized search and discovery and other value-added services.
• Aggregation vs. Broadcast search.• Providers build once, share many times.
Purpose of OAI is to foster interoperability.
National Science Foundation NSDL Program
• National Science, Technology, Engineering, Mathematics Digital Library.– http://www.nsdl.org/
• Coverage: K to Grey.
• National system for distributed science education; characterized by a set of exemplary resource collections and services.
• Highly competitive grants: 3 years, 339 proposals, 105 funded; three main categories: collections, services and targeted research.
2nd Generation Math Resources• Collaboration with UIUC Library, Wolfram
Research Inc., & COE Dept of Theoretical and Applied Mechanics.
• Project Objectives:– Adding interactive and graphical content to
two feature-rich Wolfram sites.– Generating and extracting OAI-compliant
metadata, establishing OAI Provider site, adding mathematics controlled vocabulary terms.
– Providing Search over mathematical equations.
– Developing courseware and problem libraries for TAM courses.
