This is a DCMI Working Draft.
Description of Document: Type is used to categorize the nature or genre of the content of the resource. Recommended best practice is to select a value from an enumerated list, and to identify the list being used with the scheme qualification. The content of SCHEME should be a URI of the controlled list. It may be repeated as necessary to include different categories. The following is offered as the Dublin Core default list of resource types.

The main changes in this version of the list of Resource Types are:

Proposed List of Resource Types:

Type is used to categorize the nature or genre of the content of the resource. Recommended best practice is to select a value from a controlled vocabulary. For qualified Dublin Core, the list may be identified using the scheme qualification. Resource Type may be repeated as necessary to include different categories. The following list (referred to as DCT1) is offered as the Dublin Core default list of resource types.

These can be defined and used as follows:

collection

an aggregation of items. The term collection means that the resource is described as a group; its parts may be separately described and navigated.

dataset

structured information encoded in lists, tables, databases, etc., which will normally be in a format available for direct machine processing. For example - spreadsheets, databases, GIS data, midi data. Note that unstructured numbers and words will normally be considered to be type text.

event

a non-persistent, time-based occurence. Metadata for an event provides descriptive information that is the basis for discovery of the purpose, location, duration, responsible agents, and links to related events and resources. The resource of type event may not be retrievable if the described instantiation has expired or is yet to occur. Examples - exhibition, web-cast, conference, workshop, open-day, performance, battle, trial, wedding, tea-party, conflagration.

image

the content is primarily symbolic visual representation other than text. For example - images and photographs of physical objects, paintings, prints, drawings, other images and graphics, animations and moving pictures, film, diagrams, maps, musical notation. Note that image may include both electronic and physical representations.

interactive resource

a resource which requires interaction from the user to be understood, executed, or experienced. For example - forms on web pages, applets, multimedia learning objects, chat services, virtual reality.

model

an abstraction of the real thing, i.e. some generalisation and interpretation. Models could be considered a symbolic representation. Examples include performance models, cost models, mechanical models, etc.

party

a person, organization, cultural group, or institution.

physical object

a non-human object or substance. For example - a computer, the great pyramid, a sculpture, wheat. Note that digital representations of, or surrogates for, these things should use image, text or one of the other types.

place

a geographic area.

service

a system that provides one or more functions of value to the end-user. Examples include: a photocopying service, a banking service, an authentication service, interlibrary loans, a Z39.50 or Web server.

software

a computer program in source or compiled form which may be available for installation non-transiently on another machine. For software which exists only to create an interactive environment, use interactive instead.

sound

a resource whose content is primarily audio or intended to be realized in audio. For example - music, speech, recorded sounds. This category includes musical notation, including score, which is unrealized in sound.

text

a resource whose content is primarily words for reading. For example - books, letters, dissertations, poems, newspapers, articles, archives of mailing lists. Note that facsimiles or images of texts are still of the genre text.

Future Work

Future work on qualified Dublin Core will consider the addition of subtypes to the above high level types and/or the use of other SCHEMEs for more detailed lists of values.
