Structured Document Example: the EAD

Finding Aids (used as guide to archived collections of papers, etc., such as letters between prominent people, notebooks of scientists, etc.) can now be created in a standardized format known as the EAD (Encoded Archival Description) , which is a DTD (Data Type Description) in XML

http://lcweb.loc.gov/ead/

Which means they can be searched online, and a single search engine could search across several sites, as in the American Heritage Project at UC Berkeley:

http://sunsite.berkeley.edu/amher/

Using the Online Archive of California

http://sunsite2.Berkeley.EDU/oac/

Metadata in the EAD

As an XML DTD, the EAD can define metadata elements, such as biohist and chronlist :
