2 Introduction • The OAI worldview: Data Providers and Service Providers • Service Provider: OCLC (through World. Cat and beyond) • Data Providers: you!! • What this presentation isn’t • Disclaimers
3 Background • The Open Archives Initiative Protocol for Metadata Harvesting (OAIPMH) ▫ Developed in 2001 ▫ Andrew W. Mellon Foundation grants • OAIster (University of Michigan) ▫ “Designed to establish a broad, generic information retrieval resource pointing to publicly available digital resource representations, mostly provided by the research library community” (Hagedorn, 2003) ▫ The big idea: “no dead ends” ▫ Launched as a public search interface in 2002 ▫ Harvested all exposed records, but presented only those which pointed to actual digital objects Image source: http: //www. oaister. org, via the Internet Wayback Machine
4 Background • Meanwhile… ▫ OCLC launches its Metadata Harvesting Program in 2003 • UM’s assessment: approach not scalable ▫ Early 2009: announced partnership with OCLC ▫ February 2009: OAIster records made discoverable in World. Cat via First. Search ▫ Late 2009: harvesting operations moved to OCLC • World. Cat Digital Collection Gateway ▫ Began transition in July 2010 ▫ Self-service model ▫ Compatible with all OAI-compliant repositories ▫ Optimized for CONTENTdm ▫ Free!
5 OAIster today • Name retained for public interface • Subset of World.

7 OAI-PMH • Released in 2001 • Based on dual worldview: Data Providers and Service Providers • Scalable • Relatively “simple” § Based on HTTP “verbs” § Non-MARC counterpart to Z 39. 50 • Non-invasive (your original records not affected without your intervention) • Minimum requirements set a fairly low floor § Simple Dublin Core § Unique and persistent identifier for the digital object § Community-specific applications allowed Image source: http: //www. openarchives. org/, accessed February 10, 2012
8 OAI-PMH • World. Cat Digital Collection Gateway implementation § Data provider creates collection profiles (i. e. customize metadata maps) § Data provider sets up harvesting schedule (default is quarterly) § Records are converted to MARC format for storage in World. Cat § More detail to come!! Image source: http: //www. openarchives. org/, accessed February 10, 2012
