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)?

Research Support Libraries Programme

• Support for UK academic research• Improve disclosure/discovery of, access to

collections• Improve collaborative management of

collections• Recognition of collection-level description as

important mechanism for disclosure/discovery• Need for consistent approach to CLD

– Within RSLP & beyond

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

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 concerns over status, ownership, visibility, persistence, maintenance, etc

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…)

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
