Attributes

Name	Type	Multiplicity	Description
contentUrl	XsdAnyUri	[0..1]	Documentation Original Reference schema:contentUrl Definition Actual bytes of the media object, for example the image file or video file. Scope Domain: MediaObject (https://schema.org/MediaObject). Range: URL (https://schema.org/URL). CDIF Definition schema:contentUrl - direct URL to fetch the bytes.
encodingFormat	DefinedTerm	[0..*]	Documentation Original Reference schema:encodingFormat Definition Media type typically expressed using a MIME format (see [IANA site](http://www.iana.org/assignments/media-types/media-types.xhtml) and [MDN reference](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types)), e.g. application/zip for a SoftwareApplication binary, audio/mpeg for .mp3 etc. In cases where a [[CreativeWork]] has several media type representations, [[encoding]] can be used to indicate each [[MediaObject]] alongside particular [[encodingFormat]] information. Unregistered or niche encoding and file formats can be indicated instead via the most appropriate URL, e.g. defining Web page or a Wikipedia/Wikidata entry. Scope Domain: CreativeWork (https://schema.org/CreativeWork), MediaObject (https://schema.org/MediaObject). Range: Text (https://schema.org/Text), URL (https://schema.org/URL).
