Description of Document:

 

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 IMLS funded National Leadership Grant (NLG) projects. It is meant to describe digital collections created through NLG 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 a detailed look at the elements and their attributes and to give some guidance on usage. For a less detailed look at the schema, please see the General Overview page.

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 (a 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.

See http://imlsdcc.grainger.uiuc.edu/CDschema_overview for a general overview of the IMLS DCC Collection Description Metadata Schema.

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

Each metadata element is described by the following attributes:

Name The unique token assigned to the term.
Label The human-readable label assigned to the term.
Definition A statement that represents the concept and essential nature of the term.
*Uses Encoding Scheme Name of the classification scheme for use, if required.
Obligation Indication of whether element is required or optional.
Occurrence The number of times a data element may appear.
*Refines A second element which is the super-property of the current element.
Comment

Additional information about the term or its application, including examples.
