mediumof

Mediumof is a term used in metadata schemas and data modeling to indicate the medium of a given content item—how the information is delivered or presented to the user. It is not tied to a single standardized vocabulary; rather, it appears in various contexts where a field is needed to describe the delivery format of content. Typical values include text, audio, video, image, and sometimes interactive, or a combination when multiple delivery modes apply.

In practice, mediumOf may be implemented as a property name in JSON, YAML, XML, or RDF, and can appear in different naming styles such as mediumOf, medium_of, or similar variants depending on the schema conventions. The precise semantics of the field depend on the surrounding metadata model, but the goal is usually to aid discovery, filtering, rendering decisions, or accessibility considerations by identifying the primary mode of content delivery.

Examples of usage include catalog records, digital libraries, and media repositories. A catalog entry for a podcast might use mediumOf: "audio," a photograph in a gallery might use mediumOf: "image," and a video tutorial might use mediumOf: "video." In some schemas, a resource may carry multiple mediumOf values to reflect mixed-media items, underscoring the need for clear documentation within the specific data model.

Related concepts include medium (as a broader notion), content type, format, and delivery channel. Mediumof remains an informal or schema-specific term rather than a universally adopted standard, so its interpretation should be clarified within the respective metadata framework.
