EAD Elements

<eadgrp> EAD Group

Description:

A wrapper element in the EAD Group Document Type Definition (DTD), which allows several archival finding aids encoded with the EAD DTD to be combined into a single document. The EAD Group DTD was designed as a "super wrapper" for multiple finding aids describing materials dispersed among various administrative bodies, i.e., among multiple repositories or among different custodial divisions within a single repository. The EAD Group approach makes it possible to summarize the dispersed materials in <archdescgrp> and to connect closely finding aids that should be viewed together to understand the dispersed materials. Examples of an <eadgrp> might be a set of finding aids to Mark Twain papers held in several repositories, or finding aids for moving image material and manuscript material from a single collection that was separated according to formats among custodial departments.

The <eadgrp> begins with a required <eadheader>, followed by an optional <frontmatter>, then a required <archdescgrp>. The <archdescgrp> contains not only typical <archdesc> subelements such as <did> and <bioghist>, but a special <dscgrp> to bundle the <ead> instances as subordinate components.

The EAD Group DTD should not be used for assembling documentation about multiple accessions of a single collection or fonds held by a single administrative unit; such accessions should be described in a single <ead> instance.

Use the <ead><archref> element to link between a finding aid for a large body of records and the finding aids for its subordinate series. One example of this situation is a government agency record group with series so large that each series has a separate finding aid.

To facilitate use of EAD Group as XML Schema, an xmlns attribute may be switched on in the default DTD by making the following change:

<!ENTITY % namespace
'IGNORE'
>
to <!ENTITY % namespace
'INCLUDE'
>

May contain:

archdescgrp, eadheader, frontmatter

May occur within:

Not applicable; highest-level element in EAD Group DTD.

Attributes:

ALTRENDER#IMPLIED, CDATA
AUDIENCE#IMPLIED, external, internal
ID#IMPLIED, ID
RELATEDENCODING#IMPLIED, CDATA

The AUDIENCE attribute value may be set to "external" to display data in all subelements, unless the value is changed for a specific element. To facilitate use of EAD as XML Schema, an xmlns attribute may be switched on in the default DTD by making the following change:

Change: To:
<!ENTITY % namespace
'IGNORE'
>
<!ENTITY % namespace
'INCLUDE'
>
A separate Document Type Definition called EAD Group can be used to bundle <ead> finding aids that describe different parts of a collection that have been dispersed among various institutions or custodial units. See the <eadgrp> element description for additional information.

May contain:

archdesc, eadheader, frontmatter

May occur within:

dscgrp
