<eadgrp> EAD Group

At times, a series is so large and/or complex that it must be encoded in multiple finding aids. Perhaps it is held at multiple repositories or in multiple departments or perhaps it’s a government series with many subordinate collections. In this case, EAD-encoded finding aids can be bundled together in the <eadgrp> “super wrapper” element.

Like a regular <ead> element, <eadgrp> begins with an <eadheader> element which may be followed by <frontmatter>. It then contains an <archdescgrp> elements which contains the typical <archdesc> subelements but also a <dscgrp> element which bundles the <ead> instances as subordinate components.


  • 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.
  • RELATEDENCODING – not required. This attribute can be used to denote the descriptive encoding system to which certain EAD elements can be mapped using the ENCODINGANALOG attribute. It can also be set in <ead>, <eadheader>, and <archdesc>. Setting it at a lower level than <eadgrp> allows one to map different sections to different encoding systems.


<eadgrp> must contain <eadheader> (required), <frontmatter> (optional), and <archdescgrp> (required) in that specific order.


Hypothetically, one might have the following structure:
