Thinking collectively:resource disclosure through collection-level descriptionmda Conference “Common Threads”, Edgbaston, Birmingham, 6 September 2002 Bridget Robinson(content by Pete Johnston) UKOLN, University of Bath Bath, BA2 7AY cd-focus@ukoln.ac.uk http://www.ukoln.ac.uk/ UKOLN is supported by:

    2. Thinking collectively: resource disclosure through CLD • The resource discovery context • Collections, collection description & collection-level description • Approaches to collection description • Applying collection-level description mda Conference, Edgbaston, 6 September 2002

    3. The resource discovery context • Strategic initiatives for museums • “Renaissance in the Regions” • Single Regional Agencies • Re:source Framework for Collections Management • And elsewhere…. • Libraries: • People’s Network : connectivity • Full Disclosure : retrospective cataloguing • Research Support Libraries Programme : disclosure/access, collaborative management • Archives: • Access to Archives, Scottish Archival Network, Archives Hub : integrated access mda Conference, Edgbaston, 6 September 2002

    4. The resource discovery context • Digital content creation programmes • making heritage (more) accessible • NOF-Digitise • £50m content creation programme • supporting strategy for social inclusion, lifelong learning • digitised objects • learning materials • 130 projects, Summer 2001- • Culture Online • “to widen access to resources of arts/cultural sector for purposes of learning and enjoyment” mda Conference, Edgbaston, 6 September 2002

    5. The resource discovery context • Broader resource discovery context • user wants information relevant to task/activity • may see structural/organisational boundaries of information providers as unimportant! • content providers exposing content through multiple services, channels • service providers “surfacing” content from multiple (distributed) sources • … from web sites to portals mda Conference, Edgbaston, 6 September 2002

    6. The resource discovery context • Technological context • XML everywhere…. • Open Archives Initiative Protocol for Metadata Harvesting Release Version 2.0 (stable) • enabling sharing of metadata records (using XML over HTTP) • Web Services (SOAP etc) • enabling modular distributed applications (communicating using XML over HTTP) • CIMI • Dublin Core testbed • Metadata harvesting using OAI PMH • CIMI XML Schema for SPECTRUM testbed mda Conference, Edgbaston, 6 September 2002

    7. The resource discovery context • e.g. HEIRPORT • Cross-searching metadata databases of ADS, RCAHMS, SCRAN, Portable Antiquities • Z39.50 search/retrieval protocol • Dublin Core (in XML) http://ads.ahds.ac.uk/heirport/ mda Conference, Edgbaston, 6 September 2002

    8. mda Conference, Edgbaston, 6 September 2002

    9. The resource discovery context • Access… • Integration… • Collaboration…. • “Interoperability as recombinant potential” (Dempsey, 2002) • The whole is more than the sum of the parts mda Conference, Edgbaston, 6 September 2002

    10. Collections, collection description & collection-level description

    11. What is a collection? • Collection • “an aggregation of items” • Aggregations of, e.g. • natural objects: fossils, mineral samples… • created objects: artefacts, documents, records… • digital resources: documents, images, multimedia objects, data, software… • digital surrogates of physical objects: documents, images… • metadata: catalogue records, item descriptions, collection-level descriptions (!)… mda Conference, Edgbaston, 6 September 2002

    12. What is a collection? • Various criteria for aggregation, e.g. • By location • By type/form of item • By provenance of item • By source/ownership of item • By nature of item content • …. • Permanent, temporary • Discrete, distributed • Collections created with intent/purpose • collection development policies mda Conference, Edgbaston, 6 September 2002

    13. What is a collection? • CIDOC Conceptual Reference Model draft v3.3.2, 31 July 2002 • E78 Collection • Subclass of: Physical Man-Made Stuff • Scope Note: This entity describes an aggregate of items, which is maintained by an Actor following a plan of cultural relevance over time. Things may be added or taken out of a collection in pursuit of this plan. A collection is designed for a certain public, and the conservation of the collected items is normally catered for. mda Conference, Edgbaston, 6 September 2002

    14. What is a collection? • Museums • collections of physical objects/items • collections of digital objects/items • collections of metadata records • describing physical objects • describing digital objects • Collections are made available to users through services mda Conference, Edgbaston, 6 September 2002

    15. Collection of physicalitems Physicallocation Physicalservice Physical services make physical collections available at physical locations mda Conference, Edgbaston, 6 September 2002

    16. Networkservice Website Collection of digitalitems Digitallocation Network services make digital collections available at digital locations mda Conference, Edgbaston, 6 September 2002

    17.

    18. Collection of digitalitems Digitallocation Website Networkservice Collection of digitalmetadata records Digitallocation Network services make digital collections available at digital locations mda Conference, Edgbaston, 6 September 2002

    19. User wants to know… • Which collections are relevant to their requirement? • subject/coverage of items? • type? • legal status? • conditions of access/use? • etc • What services make those collections available? • location? • access? • etc mda Conference, Edgbaston, 6 September 2002

    22. “User” wants to know… • Which collections are relevant to their requirement? • subject/coverage of items? • type? • legal status? • conditions of access/use? • etc • What services make those collections available? • location? • access? • etc • “User” may be human researcher or software tool mda Conference, Edgbaston, 6 September 2002

    23. The problem • “We’ve created this incredible constellation of collections, of pools of information accessible through the Net. And people can’t find which pool to look in” • (Lynch, 2002) mda Conference, Edgbaston, 6 September 2002

    24. Collection description • Describing the “pools”…. • Hierarchic • info about collection as whole, and about items (and relationships between items and whole) • Analytic • info about items in collection • Indexing • info derived from items in collection • Unitary • info about collection as whole, not about items • “collection-level description” • (typology from Heaney 2000) mda Conference, Edgbaston, 6 September 2002

    25. Why collection-level description? • Enable collection provider to • disclose information about collections • overview of otherwise uncatalogued items • summary where item-level detail inappropriate/unavailable • manage collections • in collaboration with other providers • inform strategic planning • e.g. Resource • assess priorities for item-level cataloguing • e.g. Full Disclosure mda Conference, Edgbaston, 6 September 2002

    26. Why collection-level description? • Enable user to • discover/locate collections • physical/digital • select collections to explore/search on basis of summary description • physical/digital • compare collections as broadly similar objects even where items heterogeneous mda Conference, Edgbaston, 6 September 2002

    27. Why collection-level description? • Enable software agents to • select (digital metadata) collections to search on behalf of user • e.g. on basis of profile/preferences • perform searches across multiple (digital metadata) collections mda Conference, Edgbaston, 6 September 2002

    28. Why not collection-level description? • What is a collection? • the “functional granularity” question • “even-ness” across contexts, domains • Absence of cross-domain consensus on schemas for CLD? • Access points for CLD • What is the “subject” of a museum collection? • Uncertainty of value of CLD, compared to item-level description? • resource managers, resource users • Collection-level description v collection asssessment? mda Conference, Edgbaston, 6 September 2002

    29. Approaches to collection-level description

    30. IMLS on collection description • “Collections should be described so that a user can discover important characteristics of the collection, including scope, format, restrictions on access, ownership, and any information significant for determining the collection’s authenticity, integrity and interpretation.” • IMLS Framework of Guidance for Building Good Digital Collections mda Conference, Edgbaston, 6 September 2002

    31. CLDs in archives • “Collections” defined by provenance of (unique, physical) items • records of organisation or individual • principle that value of individual record derives from context, relationships • Archival description • emphasis on “multi-level” resource description • hierarchical collection description • well-established standards e.g. ISAD(G), EAD • Established services: NRA, Archives Hub, A2A, SCAN etc mda Conference, Edgbaston, 6 September 2002

    32. CLDs in libraries • Focus on description of (non-unique, physical) item • well-established standards (MARC, AACR2) • shared cataloguing • emphasis on discovery • Until recently, CLD informal, unstructured • Collections defined by • location • subject • Standards • some use of MARC for CLD (especially in USA) • deployment of RSLP CD schema by RSLP projects mda Conference, Edgbaston, 6 September 2002

    33. CLDs in libraries • RSLP Collection Description project • Michael Heaney, An Analytical Model of Collections and their Catalogues • Entity-Relationship model • Implementation independent • Based mainly on library/archival view of ‘collection’ • but intended to be applicable across wide range of collection types • RSLP Collection Description schema • Andy Powell (UKOLN) • structured set of metadata attributes • simple description of subset of entities in model • attributes based on Dublin Core Element Set where possible mda Conference, Edgbaston, 6 September 2002

    34. CLDs for digital resources • Some description of aggregates of resources • use of general metadata schemas (e.g. DC, GILS) • application-specific, protocol-specific approaches • Evolution of approaches to creating digital collections • “proof of concept” (technological focus?) • greater attention to custodianship, use • focus on integration, reuse, interoperability, sustainability • (Cole 2002, Besser 2002) • Integration requires shared conventions for talking about collections • growing interest in collection-level metadata mda Conference, Edgbaston, 6 September 2002

    35. CLDs in museums • Focus on description of (unique, physical) object • for management more than discovery? • But notion of “collection” is used • collection management • collection mapping/assessment • Various criteria • type/form of item • subject • ownership/source • Some CLD (maybe not called CLD…!) • e.g. guides to holdings, directories mda Conference, Edgbaston, 6 September 2002

    36. CLDs in museums • Little standardisation? • some use of Dublin Core MES (CIMI testbed) • some use of Encoded Archival Description DTD (NHM) • some use of RSLP CD schema • Crossroads (West Mids) • Find It In London • Regional collection mapping exercises • West Midlands, South-West Region • growing interest in • sharing data within profession • using data to support disclosure as well as management • Resource Framework for Collections Management mda Conference, Edgbaston, 6 September 2002

    37. CLDs in museums • A few examples…. • FENSCORE (Natural Science collections) • http://fenscore.man.ac.uk/ • Directories including CLD • http://www.24hourmuseum.org.uk/ • http://www.cornucopia.org.uk/ • http://www.nationaltrust.org.uk/ • http://www.english-heritage.org.uk/ • Some RSLP projects include CLD for museum resources • http://www.rascal.ac.uk/ • http://www.mappingwales.ac.uk/ • http://scone.strath.ac.uk/ mda Conference, Edgbaston, 6 September 2002

    38. Applying collection-level description

    39. Collection-level description & Research Support Libraries Programme • Support for academic researchers • disclosure of collections • discovery of/access to collections • collaborative management of collections • Collections in RSLP • projects describing primarily collections of physical items (library/archive) • projects also describing digital catalogues (which describe physical items) • collections of metadata records • Projects have created subject-based or regional databases of CLDs mda Conference, Edgbaston, 6 September 2002

    40. Collection-level description & the JISC Information Environment • Content made available as collections • various content providers • Physical collections • of physical resources (e.g. books, journals) • Digital collections • of digital resources (texts, images, multimedia objects, software, datasets, “learning objects” etc) • of digital metadata records • describing physical items,digital items,physical collections • Users access content through services http://www.ukoln.ac.uk/distributed-systems/jisc-ie/arch/ mda Conference, Edgbaston, 6 September 2002

    41. Using Collections in the JISC Information Environment • HTML Web sites • Aimed at human reader not software tool • Different user interfaces, different metadata schemas • Researcher “joins up” services manually • The portal solution • task/user-centred • single point of access to range of heterogeneous network services • The “IE service registry” • Database of collection-level descriptions, service descriptions mda Conference, Edgbaston, 6 September 2002

    42. Content Web Web Web Web Service Registry Collection Description Portal Service Description End-user User Profiles The service registry in the Information Environment The vision…. End-user is “automatically” presented with relevant resources through relevant channels mda Conference, Edgbaston, 6 September 2002

    43. Surveying the landscape • CLD not a substitute for item-level description • complementing item-level discovery • enabling item-level discovery (JISC IE) • CLD as achievable goal? • RSLP CD schema for simple, high-level CLD • Useful for museums? • CLDs support “survey of information landscape” • “to identify areas rather than specific features - to identify rainforest rather than to retrieve an analysis of the canopy fauna of the Amazon basin” (Heaney, 2000) • The “navigator” of the landscape may be a human researcher or a software tool mda Conference, Edgbaston, 6 September 2002
