Encoded Archival Description (EAD)
EAD is a SGML encoded "Document Type Definition" (DTD) intended to assist in the creation of electronic finding aids. Developed at UC-Berkeley, it is now maintained and supported as a standard by the Library of Congress and is sponsored by the Society of American Archivists. EAD can be used to represent complete archival structures, including hierarchies and associations. The kinds of functionality that the EAD affords can also be implemented using the Dublin Core. It is possible to migrate records from the Dublin Core into the EAD format if necessary. It is also possible to create EAD files that point to digital images, scanned texts, and other electronic documents. EAD Help Pages are also available.
