Dublin Core Collection Description Application Profile

A DC application profile (DCAP) specifies set of terms used in a class of DC metadata description sets, typically the class of description sets which are deployed within a metadata application or within a set of applications and services operating within some domain or community. It describes the properties that are used in statements and how the use of those properties is constrained or adapted for the purposes of that application or domain.

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].

The metadata terms referenced in the DC CD AP are drawn from the Dublin Core metadata vocabularies and also from other metadata vocabularies.

The DC CD AP is independent of any particular syntax for representing description sets. Separate guidelines will describe how descriptions conforming to the DC CD AP may be represented using the conventions recommended by DCMI for expressing DC metadata using the Resource Description Framework (RDF) and using the Extensible Markup Language (XML).

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 sometimes 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 terms have Qualified Names 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 table in the following section describes how a specified property should be used in a statement within a DC metadata description.

Identifier: The URI by which the term is referenced in a DC metadata description.
Qualified Name: The Qualified Name which is typically used as an abbreviation for the term URI.
Defined By: The name and identifier of the metadata vocabulary from which the property is drawn.
Type of Term: An indication of the type of the term, according to the typology of the DCMI Abstract Model
Source Label: The short label provided for the property by its owner/maintenance agency.
Label in this DCAP: A short 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.
Source Definition: The definition provided for the property by its owner/maintenance agency.
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.
Comments: Additional information about the use of the property in the DC CD AP, typically on the values and their representation.
Refines: Properties of which the current property is a subproperty.
Refined By: Properties which are subproperties of the current property.
Uses Vocabulary Encoding Scheme: 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 the 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). Mandatory = a value URI is required, Optional = a value URI is optional (see note), Not permitted = 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). Mandatory = a value string is required, Optional = a value string is optional (see note), Not permitted = 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 the a class from which values 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). Mandatory = a rich representation is required, Optional = a rich representation is optional (see note), Not permitted = a rich representation is not permitted
Obligation: An indication of whether a statement using this property is required in a DC CD AP collection description. Mandatory = a statement using this property is required, Optional/Recommended = a statement using this property is optional but recommended, Optional = a statement using this property is optional
Condition: Information on any additional conditions on the obligation to use the property
Occurrences: The minimum and maximum number of statements referencing this property that can occur in a metadata description

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.
