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 of the project and to incorporate the needs of National Leadership Grant projects. It is meant to describe digital collections created through IMLS funded National Leadership Grant projects and does not describe in detail the projects themselves. This metadata schema forms the basis of the IMLS NLG Collection Registry which is currently in development.

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

A collection may have been created by multiple NLG 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 NLG 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.

Questions and comments can be directed to Jenny Benevento, Project Coordinator, at benevent@uiuc.edu or 217-244-7809.
