    Description: This document describes the collection type vocabulary used by the application profile for collection-level description developed by the Dublin Core Collection Description Working Group.

    Introduction

    The Collection Type (CLDType) Vocabulary provides a set of classes that can be used as values of the dc:type property in descriptions of collections. It has been developed in association with the Dublin Core Collection Description Application Profile (DC CD AP) but this vocabulary is independent of that profile and the classes defined here may be referenced in other metadata descriptions

    The Collection Type (CLDType) Vocabulary allows for the categorisation of collections in two different ways:

    • according to whether the collection is a catalogue or finding-aid for another collection
    • according to the content of the items that make up the collection

    All of these classes are defined as subclasses of the more general class dcmitype:Collection; i.e. a statement that a resource is an instance of any of the classes below implies also that the resource is an instance of the class dcmitype:Collection.

    A metadata description may include multiple statements referencing the dc:type property, so a single collection may be an instance of several of these classes.

    Note

    Where the names are listed below as Qualified Names, prefixes are assumed to be associated with Namespace Names as follows:

    • dc: http:/purl.org/dc/elements/1.1/
    • dcterms: http://purl.org/dc/terms/
    • dcmitype: http://purl.org/dc/dcmitype/
    • cld: (collection-specific properties: URIs to be confirmed, temporary Namespace Name/URI http://example.org/cld/terms#)
    • cldtype: (collection type terms: URIs to be confirmed, temporary Namespace Name/URI http://example.org/cld/type#)

    Please note that where terms have Qualified Names with the prefixes 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 vocabulary.

    Vocabulary Terms

    By Type of Collection/Catalogue

    Catalogue [cldtype:Catalogue]

    Identifier http://example.org/cld/type#Catalogue
    Name Catalogue
    Label Catalogue
    Defined By Collection Type Vocabulary
    http://example.org/cld/type#
    Definition

    A collection of individual records describing the items, and the intellectual content of those items, of a second collection. There may, in the individual records, be information about collections but that is not the focus of the catalogue. Catalogues are typically created with significant human input.

    Hierarchic Finding Aid [cldtype:HierarchicFindingAid]

    Identifier http://example.org/cld/type#HierarchicFindingAid
    Name HierarchicFindingAid
    Label Hierarchic Finding Aid
    Defined By Collection Type Vocabulary
    http://example.org/cld/type#
    Definition

    A collection of records describing the individual items, and the intellectual content of thos items, of a second collection. The records are firmly grounded within the overall arrangement of the collection, e.g. grouping together all the letters, account books etc. in an ordered sequence or sequences. Items are often not uniquely identifiable when considered in isolation, so the context of the collection is an essential element in compiling the hierarchic finding-aid. Hierarchic finding-aids are typically created with significant human input.

    Identifier http://example.org/cld/type#Index
    Name Index
    Label Index
    Defined By Collection Type Vocabulary
    http://example.org/cld/type#
    Definition

    A collection of records consisting of information derived from items in a second collection, regardless of the content of those items. By this is meant that an index - for example a robotic search engine - will index the words in a document (or catalogue record) regardless of their context and without trying to identify the discrete elements of intellectual content contained therein. Indexes are typically generated automatically by a software robot or other harvesting technology.
