Encoded Archival Description Tag Library, Version 2002

EAD Elements

<dao> Digital Archival Object

Description:

A linking element that uses the attributes ENTITYREF or HREF to connect the finding aid information to electronic representations of the described materials. The <dao> and <daogrp> elements allow the content of an archival collection or record group to be incorporated in the finding aid. These digital representations include graphic images, audio or video clips, images of text pages, and electronic transcriptions of text. The objects can be selected examples, or digital surrogates all the materials in an archival fonds or series.

Use the Extended Pointer <extptr> element to link the finding aid to electronic objects that are not part of the described materials.

Use the ACTUATE attribute to designate whether the object is displayed automatically ("onload") or only if the user requests it ("onrequest"). Use the SHOW attribute to define whether a remote resource appears at the point of the link, in a new window, or replaces the link.

See also related elements <daodesc>, <daogrp>, and <daoloc>.

While XML Linking Language (XLink) Version 1.0, which is the basis for EAD linking elements, is a stable document, examples of EAD usage are hypothetical and have not been tested in real XLink-based applications. Those wishing to use XLink are encouraged to consult the specification available online at <http://www.w3.org/TR/xlink/>.
