thumbnail (ImageObject) missing in MediaObject

[dmejia]

MediaObject has a thumbnailUrl field but it lacks a full ImageObject thumbnail field that could be used for additional image information.
ImageObject and VideoObject do support a thumbnail already (which is confusing given that they also have a thumbnailUrl).
Can the thumbnailUrl be superseded by a thumbnail field that supports both a URL and an ImageObject? This is what's done already for http://schema.org/image

makes a lot of sense - should just be a case of deprecating thumbnailURL property and replacing it with the thumbnail property, no?

I also vote for deprecating thumbnailUrl.
Moving the domain of thumbnail upward to MediaObject is the best approach.

I am looking to incorporate schema.org into our project and this issue is preventing us from doing so.

Can this issue be re-opened to deprecate thumbnailUrl in place of thumbnail?

[BrandtH22]

This issue appears to be two-fold:
1 - expanding thumbnail domain to encompass that which is covered by thumbnailUrl
2 - deprecating thumbnailUrl.

Since 2 is more thoroughly discussed in issue #239 I recommend this issue focus on 1.
I have created a PR that will expand the scope of thumbnail to match that of thumbnailUrl and will tag this issue in it.

The “consistency with the earlier thumbnailUrl” argument makes sense, as does the ability to have thumbnails expressed against arbitrary other objects without trying to enumerate them.

Thanks, all! /cc @RichardWallis - Richard could you add to release notes?

Done!
