DCMI Type Working Group

Domain Type Lists Survey

Dublin Core Metadata Initiative - Type Working Group

Editor: Ann Apps < ann.apps@man.ac.uk>

Status of this document: Deprecated
This is previous work by the Type Working Group. It will not be taken forward by DCMI.

This document is a survey of lists of types used within specific domains and by specific implementation projects. It has been assembled from information supplied as a result of requests by the DC-Type Working Group. It is probably not comprehensive because of a limited response from implementors

Comments and feedback should be sent to the working group mailing list, < dc-type@jiscmail.ac.uk>, the archives for which may be browsed at < http://jiscmail.ac.uk/lists/dc-type.html> (NOTE, you must be a member of the WG to post messages to the WG) or, alternatively, send your feedback to the Editor of this Working Draft.


Qualifiers

  1. Type Qualifier :
    Most implementors do not qualify Resource Type with a type qualifier. Exceptions are Australian Government Information Service who use qualifiers Category, aggregationLevel, documentType, serviceType, and Cooperative Online Resource Catalog (CORC) who use a Note qualifier. DCMI has decided not to recommend a Resource Type qualifier, and so any notes, etc should be included in the dc:description of the resource.
  2. Scheme Qualifier :
    Implementers tend to use their own lists of values for types, developed for their particular applications. These could be accommodated in DC-Type by using a scheme qualifier indicating the URI of the lists's definition.

Domain-specific Type Lists

Note that some of these lists contain terms which are not within the scope of "type" as defined by the DCMI Type Vocabulary. These terms are effectively excluded - only terms within scope are relevant to this survey.

Note that many of the links originally supplied for these Type Lists are no longer active. Thus some links from this page are to projects' main pages.
