Metadata, literally "data about data"; however, it might not be easy to understand with no prior experience. Murtha Baca, Head of the Digital Art History program at the Getty Research Institute in Los Angeles, notes:
Metadata provides a means of indexing, accessing, preserving, and discovering digital resources. The volume of digital information available over electronic networks has created a pressing need for standards that ensure correct and proper use and interpretation of the data by its owners and users. Well-crafted metadata is needed more now than ever before and helps users to locate, retrieve, and manage information in this vast and complex universe.
Let's look at the important concepts underpinning metadata ▼ ▼ ▼
For an oral history metadata model there are four important concepts/categories: descriptive, administrative, preservation, and technical metadata:
These concepts/categories can roughly be translated to metadata standards like Dublin Core.

Dublin CoreTM is a type of metadata standard, which has been used for oral history projects. Dublin Core (DC) is a small set of vocabulary terms developed for describing digital objects. DC is the minimum standard for describing digital objects.
Dublin Core comes in a simple (15 elements) and a larger set. The Simple Dublin Core Metadata Element Set (DCMES) includes 15 metadata elements (terms). Each element describes a property of a resource (Metadata: Standards, Schemata, and Profiles, York University). You can modify the original elements.
