University of Maryland Administrative Metadata
Tag Library
Authored by
Presentation designed by Sean Daugherty
This tag library provides current documentation for all administrative and technical metadata for digital objects in the University of Maryland Digital Collections. The University of Maryland Administrative Metadata (UMAM) DTD and element set are based on Administrative Metadata (Admin) DTD (Version 1.03) authored by Daniel McShane and Perry Roland at the University of Virginia. UMAM was designed within the local context, yet allows data to be adaptable to comply with national standards such as Dublin Core, VRA Core, or MODS.
The tag library contains definitions, notation of parent and child elements, attributes, input standards, and examples for each element. Wherever possible, links to appropriate external standards are present. UMAM is an evolving standard, and while stable, is not static. As new projects and material types are added to the repository, the standard may be modified.
