University of Maryland Administrative Metadata Tag Library
Authored by
Jennifer O'Brien Roper
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.
