I propose we add the property broadcastOfEvent to BroadcastEvent to allow authors to specify when a broadcast is of an event rather than a creative work.
BroadcastEvent currently has the property workPerformed for broadcasts of creative works like movies, tv programs, etc. While I understand some consider antelopes to be documents, it is odd to consider an event like a sports match or an awards ceremony as a CreativeWork.
One might be tempted to use subEvent or superEvent, but those don't seem appropriate either. A live broadcast is neither part of nor a parent of the event itself.
@RichardWallis, Barry Norton and I were discussing 'workPerformed' on friday, and how it doesn't work well for e.g. ExhibitionEvent, where something like a superproperty "workFeatured" might allow those events to be associated with creative works. Would such a name work here? It seems we could end up with a lot of rather similar event-to-creativework properties otherwise...
Ah, I misread. This is between broadcast events and the actual happening...
... in which case, +1 for broadcastOfEvent
Issue #768: Added broadcastOfEvent.
I implemented this in pull request #774 with an example.
Fixed in http://schema.org/docs/releases.html#v2.2 - thanks all
