Collection-level description in practice
• Collection-level description– before CLD…– in archives– in museums– in libraries– in RSLP– in the JISC/DNER– in the NOF-digitise programme

CLDs before CLD….
• Resource managers/providers create CLDs without calling them CLDs!
– summary guides– directories– descriptions of institution’s “holdings”– etc

CLDs in archives
• Description of aggregates as central feature of descriptive practice
– “Multi-level” description
• “Collections” defined by provenance of items• Archival emphasis on context of item• CLD embedded in standards for archival
description– International Standard for Archival Description
(General) (ISADG)– Encoded Archival Description (EAD)

CLDs in archives (2)
• AIM25–http://www.aim25.ac.uk/– RSLP project– ISAD(G) collection(fonds)-level
descriptions (some sub-collections) – archives/manuscript collections in HE
institutions & learned societies in London area
– also exports XML (experimentally!) as– EAD documents; RSLP CD RDF/XML records;
simple DC records via OAI

6
CLDs in archives (3)
• Archives Hub–http://www.archiveshub.ac.uk/– JISC service at MIMAS (Manchester)– EAD collection(fonds)-level descriptions
for archive collections in UK universities & colleges
– some hierarchical descriptions– EAD supports description down to item level
– Z39.50 target
Collection-level description & NOF-digitise projects, London, 22 Feb 2002

CLDs in museums
• Tendency to focus on description of object• But notion of “collection” is used
– collection management– collection assessment/mapping
• Various criteria – type/form of item– subject– ownership/source
• Some collection-level description– little standardisation?– some use of EAD, Dublin Core
Collection-level description & NOF-digitise projects, London, 22 Feb 2002
8
CLDs in museums (2)
• Cornucopia–http://www.cornucopia.org.uk/– Resource service– CLDs for UK museums– data from range of existing sources– mapping to RSLP CD schema– cross-domain considerations e.g. subject
terminologies

9
CLDs in museums (3)
• 24 hour Museum–http://www.24hourmuseum.org.uk/– developed by mda/Campaign for
Museums; now independent charity– summary CLDs– also details of events, exhibitions, “trails”,
teaching resources etc
Collection-level description & NOF-digitise projects, London, 22 Feb 2002

CLDs in libraries
• Tendency to focus on description of item– well-established standards (MARC, AACR2)
• Until recently, collection-level description informal, unstructured
• Subject-based collections– items dispersed– complex relationships
• Standards– some use of MARC for CLD (especially in USA)– adoption of RSLP CD schema in RSLP programme
Collection-level description & NOF-digitise projects, London, 22 Feb 2002
11
CLDs in libraries (2)
• SCONE–http://scone.strath.ac.uk/– RSLP project– CLDs for holdings of libraries in Scotland– complex relationships between collections– support
– collaborative collection management– “landscaping” in CAIRNS
– implements RSLP CD schema
Collection-level description & NOF-digitise projects, London, 22 Feb 2002
12
CLD in RSLP
• Support for researchers– discovery of/access to collections– collaborative management of collections
• Collections in RSLP– projects describing primarily (but not
exclusively) collections of physical items– projects also describing digital catalogues
(which describe physical items) i.e. collections of metadata records
– projects creating new digital collections of collection descriptions
Collection-level description & NOF-digitise projects, London, 22 Feb 2002
13
CLD in RSLP (2)
• RSLP CD Model & Schema– Michael Heaney (Oxford), Andy Powell
(UKOLN)– means of consistent collection description in
RSLP– simple, generic
• Adopted by number of RSLP projects– use RSLP CD schema as base descriptive
schema– or use other schema internally and map to
RSLP CD– … more later today!

CLD in RSLP (3)
• Regional– RASCAL
– http://www.rascal.qub.ac.uk/
– Mapping Wales– http://www.mappingwales.ac.uk/
• Subject-based– Caribbean Studies, Black/Asian history
CASBAH– http://www.casbah.ac.uk/
– BUFVC Researchers Guide Online – http://www.bufvc.ac.uk/

CLD in DNER
• Collections in DNER– collections of resources
– text, images, data...
– collections of metadata about resources – subject gateways, library catalogues…
– digital items, physical items– distributed
– local institutions – JISC content providers– external collections
Collection-level description & NOF-digitise projects, London, 22 Feb 2002
16
CLD in DNER (2)
• Collections available to users through services
• Network services make digital collections available at digital ‘locations’
• Real services make physical collections available at physical ‘locations’

CLD in the NOF-digitise programme
• Collections in NOF-digitise– projects creating new digital collections of
resources (images, audio, video etc)– projects creating new digital collections of
metadata records (describing digital items)– (projects maybe also describing physical
collections?)
Collection-level description & NOF-digitise projects, London, 22 Feb 2002
19
CLD in the NOF-digitise programme
• Collection-level descriptions – one CLD for all project resources as single
collection?– multiple CLDs for “sub-collections”?
– by item form/type?– by subject?
– CLD for consortial “super-collections”?
• CLDs might be created – by project – by “consortium”– by NOF on behalf of project

Introducing OAI MHP
• OAI Metadata Harvesting Protocol– lightweight protocol which allows data providers
to expose metadata records for retrieval by service providers
– data providers (projects) supply metadata as XML documents
– Must provide simple DC (OAI provides XML Schema)
– May provide other metadata formats (in XML)– OAI provides a standardised means for NOF
portal - and other portals - (service providers) to gather metadata records from projects (data providers) into central database
