<indexentry> Index Entry

<indexentry> is a wrapper element that pairs an index term with one or more linking elements. Each <indexentry> must contain an access element such as <name> or <subject>. These may use controlled vocabulary and the SOURCE attribute to facilitate access within the system. It may contain a <ptr>, <ptrgrp> or <ref> element. <ptr> should be used when no text is needed and <ref> when it is. <indexentry> may also contain a <note> element which creates subcategories.

<namegrp> may be used to bundle multiple element entries with the same <ref>, <ptr> or <ptrgrpy> element. Multiple <ref> or <ptr> links for a single access term may be bundled using <ptrgrp>.

<indexentry> may occur within <index> and higher-level <indexentry> elements.


  • 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.”
  • ID – not required. Creates an ID for element. Can be used for linking.
  • ENCODINGANALOG – not required. May contain information to map this tag to a particular element in another schema.


<indexentry> may contain further <indexentry> elements, as well as: <corpname>, <famname>, <function>, <genreform>, <geogname>, <name>, <namegrp>, <occupation>, <persname>, <ptr>, <ptrgrp>, <ref>, <subject>, and <title>. It may not contain <p> tags or plain (unencoded) text.
