Digital Collection Project Best Practices

Metadata Elements

This document provides a set of metadata elements that are highly recommended for digital collections at the Gerth Archives and Special Collections. It consists of:

(1) Dublin Core 15 Core Elements;

(2) Selected Dublin Core Terms; and

(3) Local Use Elements: These elements are intended to enhance resource discovery and be     applicable only among the digital collections at the local platform.

While it is not ideal to repeat the main title element, all elements are repeatable. Although some of the elements may or may not be relevant to the digital collection being described, it is recommended to retain the elements and leave them blank when irrelevant. Deletion is not recommended.   
Other Dublin Core Terms can be added and leveraged if they can serve sufficiently.

Label and Order of Elements

Labels can be renamed and/or modified to serve a digital collection adequately as long as they are used in the same context.

The order of the elements is flexible and can be rearranged, however, it is recommended to place the main title element at the top.

The following table lists labels, DC elements/terms, and usage and note in the recommended order.
