Outline

• DC metadata "application profiles"
• DC Collection Description AP
• Background
• Terms Used
• DC CD AP, RSLP-2000 "RSLP-2004"?

3
Dublin Core Metadata

• DCMI developing interoperable metadata standards
  to support resource discovery
• Defines, maintains, supports use of metadata
  vocabularies (DCMI Namespaces)
• Sets of DCMI terms
• For each DCMI term
• persistent, globally unique identifier
• name
• type of term (DCMI typology)
• element, element refinement, encoding scheme
• definition, notes on usage
• description of relation to other terms

4
Resources, statements, descriptions, records

• Terms used in statements about resources
• anything that can be named or described
• Each statement has the form
• Resource Property -gt Value (Resource)
• DCMI elements/element refinements are properties
• c.f. E-R model, a DC statement may describe
• an attribute of an entity
• a relationship between two entities
• A description is a set of statements about a
  single resource
• A record is a set of one or more descriptions of
  related resources

5
DC Application Profiles

• A DC Application Profile specifies
• Which properties are used within a metadata
  application
• May describe how properties constrained/adapted
  for purpose (semantic refinement, cardinality,
  value space)
• Syntax-independent
• e.g. Simple Dublin Core
• Use of properties from one vocabulary (DCMES)
• To create (very simple) descriptions of pretty
  much anything!
• e.g. RSLP-2000
• Use of properties from several vocabularies
• To create descriptions of a Collection, its
  Location, Agents
• e.g. DC CD AP
• Use of properties from several vocabularies
• To create descriptions of a Collection

6
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-2000 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

7
DC Collection Description 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-2000 as
  starting point for WG discussion
• exclude Location, Agent description (for now)

Outstanding Issues for DC CD WG/DCMI

• Decide on how to describe format of items in
  collection
• Proposals for additions to DCMI Namepaces
• provenance, isAvailableAt
• isDescriptionOf?, logo?
• Ownership/URIs of collection-specific terms
• Review in light of DCMI work on dates, rights,
  modelling
• Encoding schemes?
• Develop supporting materials
• guidelines, schemas, crosswalks
• Clarify administration of DC CD AP

13
DC CD AP, RSLP CD-2000 "RSLP-2004"?
14
DC CD AP, RSLP CD-2000 "RSLP-2004"?

• What are your requirements for CLD metadata
  schema(s)?
• Does DC CD AP meet your requirements?
• Does RSLP-2000 meet your requirements?
• Would a revised "RSLP-2004" meet your
  requirements?
• If more than one CLD metadata schema (e.g. DC CD
  AP "RSLP-2004"), what are relationships?
• technical issues, administrative issues
• etc!
