Outline
• DC metadata & "application profiles"
• DC Collection Description AP– Background– Terms Used
• DC CD AP, RSLP-2000 & "RSLP-2004"?
http://www.ukoln.ac.uk/
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

Resources, statements, descriptions, records
• Terms used in statements about resources– anything that can be named or described
• Each statement has the form– Resource – Property -> 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

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

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

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
RSLP-2000
RSLP-2004
DC CD AP, RSLP CD-2000 & "RSLP-2004"?
DC CD AP
DCMES

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!
