From collections to services • Interest in collection-level description for resource disclosure/discovery • Collection as aggregation of items • Having selected collection, agent wants access to collection • Collection made available by services • Also emergence of Web Services • Modular applications available over Web protocols • How can agent • discover/select relevant services? • obtain sufficient information to interact with services (access point, interface)?

RSLP CD Model/Schema • Entity-Relation model (Michael Heaney, Univ of Oxford) • Implementation independent • Intended to be applicable to wide range of collections • Informed by IFLA FRBR model • Models structures not transactions • Metadata schema (Andy Powell, UKOLN) • DC "application profile" • Expresses subset of RSLP model • Collection, Location, Agents • Simplification of model • Relations as elements/properties • RDF binding Distributed Service Registries Workshop

RSLP CD Model/Schema • Implementation by RSLP projects • Mostly describing physical library/archive collections • Mostly delivered via stand-alone Web sites • Initially, at least, little m2m interaction • Some work carried forward in e.g. CC-Interop • Collection Description Focus @ UKOLN • Significant influence on other initiatives • The European Library (TEL) • IMLS Collection Register • Enrich-UK (portal for digitisation programme) • Cornucopia (UK museum collections) • But concernsover status, ownership, visibility, persistence, maintenance, etc Distributed Service Registries Workshop
Dublin Core Collection Description Application Profile • Project of DCMI Collection Description Working Group • Specification of "core" set of properties for describing collections • Suitable for a broad range of collections • Primarily to support discovery and selection of collections • Informed by experience of RSLP, others (incl. IESR) • Building on Heaney E-R model • Collection properties (only) of RSLP CD schema as starting point for WG discussion • exclude Location, Agent, Service description (for now…) Distributed Service Registries Workshop

NISO Metasearch Initiative • Bringing together content providers, system vendors, library service providers, standards developers • "To identify, develop, and frame the standards and other common understandings that are needed to enable an efficient and robust information environment" • Access Management, Collection/Service Description, Search & Retrieval • For collection description • adopt/build on DC CD AP • extensions/adaptations (e.g. collection completeness) • For service description, see Rob's presentation! • NISO MI not building service, not specifying architecture http://www.lib.ncsu.edu/niso-mi/ Distributed Service Registries Workshop
