A web page. Every web page is implicitly assumed to be declared to be of type WebPage, so the various properties about that webpage, such as `breadcrumb` may be used. We recommend explicit declaration if these properties are specified, but if they are found outside of an itemscope, they will be assumed to be about the page.

Data type: URL.

A media object, such as an image, video, audio, or text object embedded in a web page or a downloadable dataset i.e. DataDownload. Note that a creative work may have many media objects associated with it on the same web page. For example, a page about a single song (MusicRecording) may have a music video (VideoObject), and a high and low bandwidth audio stream (2 AudioObject's).
