  3. Why would it be necessary? • Vision: rich public and economical service layer based on OAR-share in Open Information Commons • examples: global indexing, search, statistics, mash-ups, alerting, recommender, re-use, mining, enrichment … • OAR vision challenged by distributed nature • requires each service provider overcome heterogeneity, laboriously identify entities, aggregate metadata • COAR Global Metadata Store could be a cure • reference object registry of OA-objects free for everybody to use (or at least non-commercial use) • Benefits / Success Factors: increased visibility and re-use of local repository content > traffic, inlinks etc., Open Inf. Commons > # of service providers

  4. Practical grounds & Other Examples • Metadata Stores already there • OAIster, BASE, DRIVER, ANDS … • BUT: too laborious for COAR • Rather start from object IDs, radically web-based – URIs, namespaces, authority files • Then build raw metadata store for re-use • Other examples may exist >> CrossRef? • But none is global, open and free and operated specifically for OARs

  5. The most simple thing possible • Object Registry • Registry service, stableidentifiers etc. • Harvestingand Open Store • COAR membersrepositorycontent> noindexing • Machineinterfacesfor service providers • e.g. http, SFTP, RSYNC, OAI-PMH etc. > no GUIs • Updates plus supportforrepositorymanagers & service providerstechnicians on work-days • 24/7 deploymentattwosites • As authoritative service (SLA) ~ 5000€/month • Best effortmaybeforfree

  6. Implications: „With or Without“ • WithoutCOAR Global Metadata Store + No hassle with cost and service quality – No global authoritative starting point for service providers in distributed and possibly fragmented and complex landscape • WithCOAR Global Metadata Store + first step to “open information commons”, symbolic commitment to the proliferation of a service landscape, operating “hard assets” desired – Introduces technology and complexity to COAR
