Dublin Core Collection Description Application Profile Summary

Introduction

Note: This document presents a summary view of the application profile. For full details, see the full description of the Dublin Core Collection Description Application Profile [DCCDAP].

This document describes:

The set of terms used in a class of DC metadata description sets.
Specifically, it describes the set of terms used in a description of a collection (i.e. a "collection-level description", or "unitary finding aid" in the terminology of the Analytical Model of Collections and their Catalogues [AMCC]). A collection description conforming to this DC CD AP may be the only description in a description set or it may be part of a description set which includes descriptions of other resources related to the collection (as values in statements about the collection). Such other resources include the location of the collection, the services that provide access to the collection, concepts that are the subject of the collection, and other collections. While this DCAP permits the inclusion of descriptions of those related resources, it does not specify the properties and classes that may be referenced in descriptions of resources other than collections.
How the terms in this set are deployed in this class of DC metadata descriptions.
This includes requirements for the the occurrence of statements using a specified property, constraints on the types of value which are referenced in a statement using a specified property (vocabulary encoding schemes), and constraints on the datatypes of the value strings occurring in a statement using a specified property (syntax encoding schemes).

The terms description set, description, property, value, vocabulary encoding scheme, value representation, rich representation, value string, syntax encoding scheme, and related description are used in the sense they are used in the DCMI Abstract Model [DCAM].

This document is not a description of an XML format. There may be multiple bindings of the DC CD AP to XML and to other syntaxes.

Outstanding Isssues

This DCAP is currently work-in-progress. Two major issues are still under discussion:

Clarification (at the level of the data model) of the nature of the Location and Service entity types, and the relationships between Collection and Location and Collection and Service. The properties gen:isLocatedAt and gen:isAccessedVia currently listed below should be treated as provisional placeholders for a solution.
How to represent the information that a collection contains some items of specified formats. The outcome of this decision may also result in changes to the representation of the information that a collection contains items of a specified type.

Vocabularies/Namespaces used in this DCAP

All references to properties and classes in DC metadata descriptions are made using URIs, In this document, Qualified Names of the form prefix ":" local-part are used as abbreviations for URIs which identify metadata terms. Prefixes are assumed to be associated with Namespace Names (URIs) as follows, and the corresponding URI for the term is constructed by concatenating the Namespace Name and the local-part:

Vocabulary Title	Namespace Name	Prefix
The Dublin Core Metadata Element Set, v1.1	http://purl.org/dc/elements/1.1/	dc
Dublin Core Terms	http://purl.org/dc/terms/	dcterms
Dublin Core Type Vocabulary	http://purl.org/dc/dcmitype/	dcmitype
MARC Relator Code Properties	http://www.loc.gov/loc.terms/relators/	marcrel
Collection Description Terms (collection-specific terms)	http://example.org/cld/terms# [temporary URI, final URI to be confirmed]	cld
General Description Terms (non-collection-specific terms)	http://example.org/gen/terms# [temporary URI, final URI to be confirmed]	gen
Collection Type Vocabulary Terms	http://example.org/cld/type# [temporary URI, final URI to be confirmed]	cldtype

Please note that where the Qualified Name of a term (property/class) appears against a shaded background in the table below (i.e. all terms with the prefixes gen, cld and cldtype), this indicates that those terms have not yet been assigned persistent URIs. Until such persistent URIs are assigned, by DCMI or by some other naming authority, these terms should be considered to be unstable and should not be referenced in metadata descriptions, except as part of the evaluation/testing of this profile.

Property Usage

Each main row in the table below describes how a specified property should be used in a statement within a DC metadata description.

Label: A short human-readable label that provides an indication of how the property is to be used in a DC CD AP collection description. The label does not appear in the description. It may be used to provide a descriptor for fields in displays of DC CD AP collection descriptions, but there is no requirement for display applications to use this label.
Property: A unique name/identifier for the property. It is presented as a Qualified Name, but is an abbreviation for a URI. This URI must be used to refer to the property in DC CD AP collection descriptions.
Usage in this DCAP: A description of how the definition of the property is to be applied in DC CD AP collection descriptions. This information supplements the definition of the property provided by its owner/maintenance agency.
Obligation: An indication of whether a statement using this property is required in a DC CD AP collection description. M = a statement using this property is required, OR = a statement using this property is optional but recommended, O = a statement using this property is optional
Vocabulary Encoding Scheme(s): The unique names/identifiers of classes from which values for the property should be drawn. Names are presented as Qualified Names, but are abbreviations for URIs. The URI must be used to refer to the class in DC CD AP collection descriptions. If no class is listed, then the DC CD AP does not specify a class from which values should be drawn. However the definition and usage of the property may determine that values of only certain types are appropriate. For example, the value of the dc:creator property must be an entity capable of action.
Value URI: An indication of whether a value URI is to be used in a statement using the property (and vocabulary encoding scheme, where specified). M = a value URI is required, O = a value URI is optional (see note), N = a value URI is not permitted
Value String: An indication of whether a value string is to be used in a statement using the property (and vocabulary encoding scheme, where specified). M = a value string is required, O = a value string is optional (see note), N = a value string is not permitted
Syntax Encoding Scheme(s): The unique names/identifiers of datatypes from which value strings for the property should be drawn. Names are presented as Qualified Names, but are abbreviations for URIs. The URI must be used to refer to the datatype in DC CD AP collection descriptions. If no datatype is listed, then the DC CD AP does not specify a datatype from which value strings should be drawn.
Rich Representation: An indication of whether a rich representation is to be used in a statement using the property (and vocabulary encoding scheme, where specified). M = a rich representation is required, O = a rich representation is optional (see note), N = a rich representation is not permitted

Note: For each value, at least one of the following components must be present: a value URI, a rich representation, a value string or a (related) description.

Added "Outstanding Issues" list.
Replaced label "Definition" with "Usage in DC CD AP".
Added details of whether Value URI/Value String/Syntax Encoding Scheme/Rich Representation required, per vocabulary encoding scheme.
Removed usage of dc:format property ("Physical Characteristics") (pending decision on how to represent information that collection contains items of specified format).
Altered name of cld:logo ("Logo") property to gen:logo (as could be applied to other resource types).
