Distributed Service Registries Scope of IESR JISC, UK, international? Scalability and Data ownership issues Distributed / federated model Each node describes own resources How to cross search? Metasearch; UDDI; OAI-PMH harvest IESR collaboration with OCKHAM in US Replication by OAI-PMH; search local 2006-06-15 ELPUB2006
Sharing Descriptions Sharing collection descriptions Created by resource provider Need common / derivable metadata schema NISO Metasearch Initiative OAI-PMH to share descriptions OAI-PMH includes provenance and rights containers Rights issues: common CC Licence? 2006-06-15 ELPUB2006
