Properties

Properties of ImageObject	Expected Type	Description
caption	MediaObject or Text	The caption for this object. For downloadable machine formats (closed caption, subtitles etc.) use MediaObject and indicate the encodingFormat .
representativeOfPage	Boolean	Indicates whether this image is representative of the content of the page.
thumbnail	ImageObject	Thumbnail image for an image or video.

Properties inherited from MediaObject	Expected Type	Description
associatedArticle	NewsArticle	A NewsArticle associated with the Media Object.
bitrate	Text	The bitrate of the media object.
contentSize	Text	File size in (mega/kilo) bytes.
contentUrl	URL	Actual bytes of the media object, for example the image file or video file.
duration	Duration	The duration of the item (movie, audio recording, event, etc.) in ISO 8601 date format .
embedUrl	URL	A URL pointing to a player for a specific video. In general, this is the information in the `src` element of an `embed` tag and should not be the same as the content of the `loc` tag.
encodesCreativeWork	CreativeWork	The CreativeWork encoded by this media object.
encodingFormat	Text or URL	Media type typically expressed using a MIME format (see IANA site and MDN reference ) 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.
endTime	DateTime or Time	The endTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to end. For actions that span a period of time, when the action was performed. e.g. John wrote a book from January to December. For media, including audio and video, it's the time offset of the end of a clip within a larger file. Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.
height	Distance or QuantitativeValue	The height of the item.
playerType	Text	Player type required—for example, Flash or Silverlight.
startTime	DateTime or Time	The startTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to start. For actions that span a period of time, when the action was performed. e.g. John wrote a book from January to December. For media, including audio and video, it's the time offset of the start of a clip within a larger file. Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.
uploadDate	Date	Date when this media object was uploaded to this site.
width	QuantitativeValue or Distance	The width of the item.

In the case of a Dataset it will typically indicate the relevant time period in a precise notation (e.g. for a 2011 census dataset, the year 2011 would be written "2011/2012"). Other forms of content e.g. ScholarlyArticle, Book, TVSeries or TVEpisode may indicate their temporalCoverage in broader terms - textually or via well-known URL. Written works such as books may sometimes have precise temporal coverage too, e.g. a work set in 1939 - 1945 can be indicated in ISO 8601 interval format format via "1939/1945". Open-ended date ranges can be written with ".." in place of the end date. For example, "2015-11/.." indicates a range beginning in November 2015 and with no specified final date. This is tentative and might be updated in future when ISO 8601 is officially updated.

For something that can be commercially licensed, usageInfo can provide detailed, resource-specific information about licensing options. This property can be used alongside the license property which indicates license(s) applicable to some piece of content. The usageInfo property can provide information about other licensing options, e.g. acquiring commercial usage rights for an image that is also available under non-commercial creative commons licenses.
