EAD Summary

More web resources for EAD

Usage
The standard for encoding archival finding aids (inventories, registers, indexes, and guides which describe and facilitate access to collections). Though not originally designed for, is also used for image collections.


Creators
Initial development began at University of California, Berkeley, Library in 1993. Society of American Archivists involvement began in 1995. First complete version released Aug. 1998. Currently maintained in the Network Development and MARC Standards Office of the Library of Congress (LC) in partnership with the Society of American Archivists.


Revisions
SAA (Society of American Archivists) will continue revision and publication of EAD Version 1.0 application guidelines. No specific timeline for new versions or updates. Encoded Archival Description Electronic List: http://lcweb.loc.gov/ead/eadlist.html .


Ease of use
Data input can be made easy with use of templates. Implementation can be done without extensive training. Display mechanism needed for viewing and searching. Some implementation guidelines and canned templates in the EAD Cookbook: http://jefferson.village.virginia.edu/ead/cookbookhelp.html

Granularity
Allows for any level of description desired, from collection to item level. Allows for nesting of data to 12 levels through the use of the Component Elements (5 or fewer typically used). Data may be linked to other EAD files through the Archival Reference element.


Data for Original and Surrogate

Provides for data of the original (can be multiple levels - such as finding aid & collection) as well as for the surrogate.


Metadata types
Descriptive metadata is provided for through the majority of EAD tags. Administrative metadata is provided for through the Administrative Info, Archival Description and other elements. Structural metadata is limited, through elements such as EAD Identifier.
