Description of Document:	This document is a summary of the IMLS DCC Collection Description Metadata Schema

The IMLS DCC Collection Description Metadata Schema is based on the UKOLN RSLP Collection Description Metadata Schema and the Dublin Core Collection Description Application Profile. The IMLS DCC project has adapted these schemas to reflect the particular nature and needs of the included projects. It is meant to describe digital collections created through IMLS Grant projects and does not describe in detail the projects themselves. This metadata schema forms the basis of the IMLS DCC Collection Registry.

The following is meant only to give a cursory overview of the schema. There are four entities described by the schema:

the collection;
the IMLS project (if applicable);
the institution; and
the administrator.

A collection may have been created by multiple projects and have multiple administrators. A collection may have only one hosting institution, but may have multiple contributing institutions. A collection may have multiple sub-collections, associated collections, or source physical collections. A project may have only one administering institution, but may have multiple participating (or collaborating) institutions. The diagram below illustrates the relationships between these entities.

Relationships between Collection Description Entities

The IMLS DCC Collection Description Metadata Schema reuses metadata elements from other schemas and adapts their use. We have also developed elements that are needed for our purposes, but have mapped these to other standards as is possible (our crosswalk is coming soon). At the bottom of this page is a list of the vocabularies and namespaces used within the IMLS DCC CD schema.

A detailed look at individual elements, their attributes, and guidance on use is available. An XML Schema is also available.
