  5. The resource discovery context • Initiatives to improve access to services • political/economic drivers • High-level strategies • UK “Modernising government” White paper • e-Government strategies • Better connectivity • public library networking through “People’s Network” • recognition of multiple channels of access • Improved resource disclosure • e.g. Full Disclosure, Research Support Libraries Programme, Archives Hub, Access 2 Archives, Scottish Archival Network etc CIMI Forum, Edinburgh, 31 October 2002

  6. The resource discovery context • Collaborative approaches to service provision and resource management • Move away from “silo mentality” • Towards more “joined-up” approaches • Within museum domain • Across domains • Embedded in strategic initiatives for museums • Re:source (England) • Single Regional Agencies • “Preserving the Past for the Future”: Framework for Collections Management • Cross-domain projects CIMI Forum, Edinburgh, 31 October 2002

  8. The resource discovery context • Functional separation of content provision and presentation • user wants information relevant to task/activity • may see structural/organisational boundaries of content providers as unimportant! • content providers exposing content through multiple services, channels • service providers “surfacing” content from multiple (distributed) sources • … from web sites to “portals” • “A network service that provides a personalised, single point of access to a range of heterogeneous network services, local and remote, structured and unstructured” • Powell 2002 CIMI Forum, Edinburgh, 31 October 2002

  18. Collections and services

  19. 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 (!)… CIMI Forum, Edinburgh, 31 October 2002

  20. 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 • …. • Any number of items • Permanent, temporary • Discrete, distributed • Collections created with intent/purpose • “consciously formed” • collection development policies CIMI Forum, Edinburgh, 31 October 2002

  21. What is a collection? • Functional granularity • “[T]here is no structure inherent in the model that requires or predisposes a particular level of aggregation. The institution should base its choices on its own pragmatic grounds, such as the level of detail required to make explicit those elements of the Collection-Description that the institution deems to be useful or necessary for the purposes of resource discovery or collection management. i.e. institutions should adopt a functional granularity approach.” • Heaney, 2000 CIMI Forum, Edinburgh, 31 October 2002

  22. Collections and services • Collections are made available to users through services • Museum collections • collections of physical objects/items • collections of digital objects/items • collections of metadata records • describing physical objects • describing digital objects • Museum services • physical services • digital/network services CIMI Forum, Edinburgh, 31 October 2002

  30. 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) CIMI Forum, Edinburgh, 31 October 2002

  31. Describing collections

  32. Collection description • Analytic • info about items in collection and their content • Indexing • info derived from items in collection • Hierarchic • info about collection as whole, and about items and their content (and relationships between items and whole) • Unitary • info about collection as whole, not about items • “collection-level description” • (typology from Heaney 2000) CIMI Forum, Edinburgh, 31 October 2002

  33. Why collection-level description? • Enable collection provider to • disclose information about collections to potential users • overview of otherwise uncatalogued items • summary where item-level detail inappropriate/unavailable • manage collections • audit/review holdings internally • manage in collaboration with other providers • assess priorities for item-level cataloguing • inform strategic planning • institutional, cross-institutional, regional, sectoral, national…. CIMI Forum, Edinburgh, 31 October 2002

  34. Why collection-level description? • Enable user to • discover/locate collections • select collections to explore/search on basis of summary description e.g. • content/coverage, access conditions, resource type • compare collections as broadly similar objects (even where items heterogeneous) • understand conditions of access & use • interpret collections • provenance, context, relationships • Enable software agents to • select collections to search on behalf of user • e.g. on basis of profile/preferences • control searches across collections CIMI Forum, Edinburgh, 31 October 2002

  35. What information should collection-level description provide? • IMLS on describing collections… • “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 CIMI Forum, Edinburgh, 31 October 2002

  36. Approaches to CLD 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 • (Mainly) physical collections made available by physical services • Archival description • emphasis on “multi-level” resource description • hierarchical collection description • well-established standards e.g. ISAD(G), EAD CIMI Forum, Edinburgh, 31 October 2002

  37. Approaches to CLD in archives • Encoded Archival Description (EAD) • SGML/XML Document Type Definition for encoding archival finding aids • Owned/maintained by Society of American Archivists/Library of Congress • Hierarchical finding-aids • “Structured document” approach • Designed to encompass broad range of existing practice • Basis of established services • Online Archive of California • RLG Archival Resources • UK Public Record Office, Archives Hub, A2A etc http://www.loc.gov/ead/ CIMI Forum, Edinburgh, 31 October 2002

  38. Approaches to CLD in libraries • Focus on description of (non-unique, physical) item • well-established standards (MARC, AACR2) • shared cataloguing • emphasis on discovery • Collections defined by • location • subject • Until recently, CLD informal, unstructured • some use of MARC for CLD (especially in USA) • deployment of RSLP CD schema by RSLP projects CIMI Forum, Edinburgh, 31 October 2002

  39. Approaches to CLD 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 • Functionally (IFLA FRBR) concerned with : • Finding (provide access points for discovery) • Identifying (describe sufficiently well for user interpretation) http://www.ukoln.ac.uk/metadata/rslp/ CIMI Forum, Edinburgh, 31 October 2002

  40. Approaches to CLD in libraries • RSLP Collection Description schema • Andy Powell (UKOLN) • structured set of metadata attributes • some simplification of model • description of subset of entities in model • attributes based on Dublin Core Element Set where possible • RSLP CD schema supports creation of “unitary” collection description • simple high-level description • not a substitute for richer CLD schema • RSLP CD instance • set of linked descriptions of several resources CIMI Forum, Edinburgh, 31 October 2002

  42. Approaches to CLD 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 CIMI Forum, Edinburgh, 31 October 2002

  43. Approaches to CLD in museums • Focus on description of (unique, physical) object • for management more than discovery? • But concept of “collection” is present • Various criteria • type/form of item • subject • ownership/source • audience/purpose • Some CLD (maybe not called CLD…!) • e.g. guides to holdings, directories, gateways CIMI Forum, Edinburgh, 31 October 2002

  44. Approaches to CLD in museums • 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. • (emphasis added) CIMI Forum, Edinburgh, 31 October 2002

  45. FENSCOREhttp://fenscore.man.ac.uk/ set up in early 1980's CLDs for UK biological collections, other than those in the NHM CIMI Forum, Edinburgh, 31 October 2002

  46. Cornucopiahttp://www.cornucopia.org.uk/ Service provided by Re:source 1800 institution-level records, collection-level data from regional “collection mapping” exercises Current work to expand coverage, enhance interoperability CIMI Forum, Edinburgh, 31 October 2002

  47. 24 Hour Museumhttp://www.24hourmuseum.org.uk/ Launched by mda/Campaign for Museums, now independent charity with funding from DCMS/Re:source Institution records, plus events/articles/educational resources; virtual exhibits Potential for embedding CLDs from Cornucopia CIMI Forum, Edinburgh, 31 October 2002

  48. Approaches to CLD in museums • Project/service specific approaches • Informal? • Limited standardisation? • However, growing interest in • repurposing management data to support disclosure • sharing data across systems • Requires harmonisation of approaches • some use of Encoded Archival Description DTD • Museums in the Online Archive of California • The Natural History Museum • some use of RSLP CD schema • Crossroads (West Midlands), Find It In London • building consensus on community schema e.g. BioCase CIMI Forum, Edinburgh, 31 October 2002

  49. Collection-level descriptionin practice

  50. 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 http://www.rslp.ac.uk/ CIMI Forum, Edinburgh, 31 October 2002
