  1998-1999
• Research Support Libraries Programme (RSLP) Model
  Schema, 1999-2000

Collections

• Collection
• an aggregation of one or more items
• aggregation by
• e.g. location, type/form of item, provenance of
  item, source/ownership of item, nature of item
  content, etc!
• varying size, degrees of permanence
• varying types of items
• natural objects, created objects, digital
  resources, digital surrogates of physical
  objects, metadata records
• items may not be physically juxtaposed

4
Collections and collection description

• What is a collection (and what is not)?
• "Functional granularity" (Heaney)
• Pragmatic choice
• Based on what is "useful or necessary for the
  purposes of resource discovery or collection
  management"
• Collection-level description
• "unitary finding aid" (Heaney)
• information about the collection as a whole,
  rather than the individual items

5
Why collection-level description?

• Enable user to
• discover/locate collections
• select collections to explore on basis of summary
  description
• compare collections as broadly similar objects
  (even where items heterogeneous)
• understand conditions of access use
• interpret collections
• Enable software agents to
• discover/locate/select collections to search on
  behalf of user
• control searches across collections

6
e-Lib Simple Collection Description

• JISC e-Lib programme, 1994-2000
• "An exploration of ways IT could assist
  libraries"
• context UK HE re-organisation, emergence of Web
• not strictly a "digital library research
  programme", but did include elements of applied
  research
• 1997-2000 Phase 3 consolidation, extension in
  key areas
• Interest in collection-level description
• Primarily to support resource discovery
• "Landscaping"
• eLib Collection Description WG
• "Simple Collection Description" schema (draft)
• Collection made available by Service
  (many-to-many)

RSLP CD Model and Schema

• Research Support Libraries Programme, 1999-2002
• Support for academic research
• Improve disclosure/discovery of, access to
  collections
• Improve collaborative management of collections
• Primarily describing physical library/archive
  collections
• Recognition of CLD as important mechanism for
  disclosure/discovery

9
RSLP CD Model

• RSLP Collection Description Project, 1999-2000
• Funded by RSLP, OCLC
• Provide means of consistent collection
  description in RSLP
• Entity-Relation model (Michael Heaney, University
  of Oxford)
• Implementation independent
• Intended to be applicable to wide range of
  collections
• Informed by IFLA FRBR approach as well as
  existing descriptive standards
• Models structures not transactions
• Support
• Finding (access points for discovery)
• Identifying (sufficient for user interpretation)

10
RSLP CD Model
11
RSLP CD Schema

• RSLP Collection Description metadata schema (Andy
  Powell, UKOLN)
• Set of metadata elements (based on Dublin Core)
• Also collection/catalogue type vocabulary
• Expresses subset of RSLP model
• Collection, Location, Agents
• Simplification of model
• Relations as elements/properties
• Supports creation of "unitary" finding aid
  (collection-level description)
• Recommends use of RDF/XML syntax for
  representation

RSLP CD Schema implementation

• RSLP projects
• Model and/or schema by number of RSLP projects as
  basis for database structure
• Mostly to deliver Web sites for human readers
• Limited exchange of CLD metadata between
  applications
• Influence on other initiatives
• The European Library (TEL)
• Institute of Museum and Library Services (IMLS)
  Collection Register
• Enrich-UK (portal for digitisation programme)
• Cornucopia (UK museum collections)
• JISC Information Environment Service Registry
  (IESR)

16
The European Library (TEL)

• Co-operative project under the Conference of
  European National Librarians (CENL)
• 8 European national libraries ICCU (Italian
  central cataloguing institution)
• Project completed Jan 2004, plans to develop
  service
• Portal providing access to distributed
  collections
• Use of collection-level description to select
  services
• TEL application profile for collection-level
  description
• Based on DC Libraries AP and Collection and
  Location attributes from RSLP CD Schema
• Some overlap between properties?
• Includes access point of Service as dcidentifier
  of Collection

DC Collection Description WG

• Background
• Growing interest in use of collection-level
  metadata to support resource disclosure/discovery
• RSLP CD Model and/or RSLP CD schema implemented
  by several initiatives in UK
• Significant influence on other CLD metadata
  schemas
• Status, ownership, persistence issues
• Charter
• Provide forum for sharing information about CLD
  activity
• Develop a DC AP for collection-level description
• Develop supporting materials for use of AP

http//dublincore.org/groups/collections/
20
DC Collection Description AP

• DC CD AP
• For simple collection-level descriptions
• Suitable for a broad range of collections
• Primarily to support discovery and selection of
  collections
• A "core" set of collection description properties
  to support interoperability
• Informed by experience of RSLP, CD Focus (UKOLN),
  TEL, JISC IESR, IMLS, others
• Collection properties (only) of RSLP CD schema as
  starting point for WG discussion
• exclude Location/Service, Agent description (for
  now)
• but building on Heaney E-R model

Outstanding Issues for DC CD WG/DCMI

• Clarify Collection-Location/Service relation
• Decide on how to represent format of items in
  collection
• Proposals for additions to DCMI Namepaces
• provenance, isAvailableAt (awaiting UB decision)
• logo?
• Collection-specific terms (accrualStatus,
  accumulationDateRange, contentsDateRange)
• Review in light of DCMI work on dates, modelling
• Develop supporting materials
• guidelines, schemas, crosswalks

24
ISO 2146

• ISO 2146 Information and documentation
  Directories of libraries and related
  organizations
• Under revision to form a data dictionary
  framework for directory applications
• Schema/syntax/protocol-independent
• Object-oriented model for
• Organisations
• Collections
• Services
• Activities
• Shift away from "organisation-centred" model so
  that each can be primary object

25
ISO 2146

• Service
• Integrated approach to physical and digital
  services
• Detailed model for service description
• Access times, permitted users, charges etc
• Collection
• Name, category, coverage, etc
• Relations between collections
• Collection profile
• Item types, accruals, policies (archival,
  disposal)
• Collection strength
• Current, planned

26
Collections, Locations Services

• Item
• A physical or digital entity
• Collection
• An aggregation of one or more items
• Service
• The provision of, or system of supplying, one or
  more functions of interest to an end-user or
  software application.
• Physical or digital
• Digital services may be structured or
  unstructured
• Informational services
• Provide access to, or metadata about, items
  and/or collections
• JISC Information Environment Architecture
  Glossary
• Location
• A place where a collection is held
• Michael Heaney, Analytical Model

27
Collection Location (RSLP)
Collection

Collection
Network Service
Is Service a subtype of Location? Is relation
between Collection and Locationsame as relation
between Collection and Service?

Collection Location Service?

Summary

• RSLP model influence on several CD schemas
• RSLP CD Schema
• Subset/simplification of RSLP model
• Collection, Location, Agents
• TEL AP
• builds on RSLP CD and DC Libraries AP
• DC CD AP as a core CD element set
• supports description of Collection only
• still in progress
• relationship of Collection and Location/Service
• ISO 2146
• Object model
• Rich service description

30
Some questions

• What range of collections and services are we
  describing?
• What are our "functional requirements" for
  collection/service description?
• What operations should metadata support?
• Human readers? Software agents?
• What information required to enable those
  operations?
• Attributes, relations
• Do existing models/schemas meet those
  requirements?
