A Metadata Element Set is a structured collection of metadata elements that describe specific attributes of a resource, such as a document, image, or dataset. These elements provide essential information, including title, author, date of creation, and subject, which help users understand and locate the resource more effectively. Commonly used in digital libraries and databases, a metadata element set ensures consistency and interoperability across different systems. Examples of widely recognized sets include the Dublin Core and MARC (Machine-Readable Cataloging), which facilitate the organization and retrieval of information in various contexts.
