  • Field Details

    • FORMAT

      Typically, Format may include the media-type or dimensions of the resource. Format may be used to determine the software, hardware or other equipment needed to display or operate the resource. Examples of dimensions include size and duration. Recommended best practice is to select a value from a controlled vocabulary (for example, the list of Internet Media Types [MIME] defining computer media formats).
      See Also:

    • IDENTIFIER

      static final String IDENTIFIER
      Recommended best practice is to identify the resource by means of a string or number conforming to a formal identification system. Example formal identification systems include the Uniform Resource Identifier (URI) (including the Uniform Resource Locator (URL)), the Digital Object Identifier (DOI) and the International Standard Book Number (ISBN).
      See Also:

    • MODIFIED

      static final String MODIFIED
      Date on which the resource was changed.

    • CONTRIBUTOR

      static final String CONTRIBUTOR
      An entity responsible for making contributions to the content of the resource. Examples of a Contributor include a person, an organisation, or a service. Typically, the name of a Contributor should be used to indicate the entity.
      See Also:

    • COVERAGE

      static final String COVERAGE
      The extent or scope of the content of the resource. Coverage will typically include spatial location (a place name or geographic coordinates), temporal period (a period label, date, or date range) or jurisdiction (such as a named administrative entity). Recommended best practice is to select a value from a controlled vocabulary (for example, the Thesaurus of Geographic Names [TGN]) and that, where appropriate, named places or time periods be used in preference to numeric identifiers such as sets of coordinates or date ranges.
      See Also:

    • CREATOR

      static final String CREATOR
      An entity primarily responsible for making the content of the resource. Examples of a Creator include a person, an organisation, or a service. Typically, the name of a Creator should be used to indicate the entity.
      See Also:

    • DATE

      static final String DATE
      A date associated with an event in the life cycle of the resource. Typically, Date will be associated with the creation or availability of the resource. Recommended best practice for encoding the date value is defined in a profile of ISO 8601 [W3CDTF] and follows the YYYY-MM-DD format.
      See Also:

    • DESCRIPTION

      static final String DESCRIPTION
      An account of the content of the resource. Description may include but is not limited to: an abstract, table of contents, reference to a graphical representation of content or a free-text account of the content.
      See Also:

    • LANGUAGE

      static final String LANGUAGE
      A language of the intellectual content of the resource. Recommended best practice is to use RFC 3066 [RFC3066], which, in conjunction with ISO 639 [ISO639], defines two- and three-letter primary language tags with optional subtags. Examples include "en" or "eng" for English, "akk" for Akkadian, and "en-GB" for English used in the United Kingdom.

      See Also:

    • RIGHTS

      static final String RIGHTS
      Information about rights held in and over the resource. Typically, a Rights element will contain a rights management statement for the resource, or reference a service providing such information. Rights information often encompasses Intellectual Property Rights (IPR), Copyright, and various Property Rights. If the Rights element is absent, no assumptions can be made about the status of these and other rights with respect to the resource.
      See Also:

      static final String SUBJECT
      The topic of the content of the resource. Typically, a Subject will be expressed as keywords, key phrases or classification codes that describe a topic of the resource. Recommended best practice is to select a value from a controlled vocabulary or formal classification scheme.
      See Also:

    • TITLE

      static final String TITLE
      A name given to the resource. Typically, a Title will be a name by which the resource is formally known.

    • TYPE

      static final String TYPE
