<function> Function

<function> is used to encode terms for spheres of activities and processes that generated the described materials. The terms may provide useful access points, such as “entertaining” or “collecting taxes.” This should not be confused with the <occupation> element, which designates a type of work of business.

The element may be used to tag any function during a paragraph, with the @normal attribute supplying the proper form of the term. It may be used within <abstract>, <archref>, <bibref>, <controlaccess>, <entry>, <event>, <indexentry>, <item>, <namegrp>, <p>, <physfacet>, <ref>, and <unittitle>. Functions which contributed greatly to the formation of the materials should be listed within <controlaccess> even if they are indicated elsewhere.


  • @altrender – not required. Use if the content of the element should be displayed or printed differently than the rendering established in a style sheet for other occurrences of the element.
  • @audience – not required. Use to set whether the element’s contents will be visible to external users or to internal ones. Possible values are: “internal” and “external.”
  • @encodinganalog – not required. May contain information to map this tag to MARC field 657.
  • @id – not required. Creates an ID for element. Can be used for linking.
  • @identifier – not required. A machine-readable unique identifier related to the content of the element. On access terms and other elements whose content is drawn from an authority file, the unique identifier for the term being used. If this attribute is used, @source should also be used to identify the authority file.
  • @lang – not required. Three-letter code that indicates the language in which the element’s contents were written. It should come from ISO 639-2b.
  • @localtype – not required. This attribute may be used within a number of elements. Its use and values are not defined by the schema and may be defined locally.
  • @normal – not required. Can be used to provide the authority form if the name is being used informally within narrative text, etc.
  • @relator – not required. May be used to designate the role which the corporate entity played in the collection, e.g. “compiler,” “creator,” “subject,” etc.
  • @rules – not required. May be used to specify the descriptive rules followed when forming the name.
  • @source – not required. The source of the controlled vocabulary, e.g. “lcsh” for Library of Congress Subject Headings.

Child Elements

<function> must contain at least one <part> element and may contain more.


<function encodinganalog="657"><part>voter registration</part></function>

Changes from EAD 2002

<function> gained @lang, @localtype, and @script. It lost @authfilenumber. It lost all child elements except <part>, which now much be used to encode all information.
