vocabularies

The closed family of shapes a media pointer may take. A property that points at this vocabulary holds a locator for a picture, video or document — a web address, or a reference into a catalogue's own managed asset library — never the bytes themselves and never arbitrary prose. Binding a text property here is what lets a form offer upload / paste-a-link / pick-from-library instead of a bare text box.

Answers the questions: media, reviewer media.
