Dear all,

This is summary of the comments received:


-          We'll add a 'free' property as a flag signalling if an event is freely accessible or not. It is applicable at the BroadcastEvent on OnDemandEvent level, both being defined as domains  of the property with a 'boolean' range -> http://www.w3.org/wiki/WebSchemas/TVRadioSchema# updated accordingly

-          We have received an offline comment from MovieLabs, suggesting that the 'position' property might actually have values other than 'integer' numbers. There are two possible options to solve this problem. Option 1 would consist of changing the datatype of 'position' to 'string' or alternatively 'literal'. Option 2 would be to have a new additional property. Any views?

Best regards,

Jean-Pierre

Hi Richard,

Yes, true. Thanks for this. We can therefore update our page with an additional attribute "free" and then up to those who want to add specialised classes to decide for themselves. Although, thinking about it, having "free" at the Event class level might work as well (all events being potentially accessible for free or not. One way or the other works for me.

Let's see if we get more feedback.

JP

Looking good, Jean-Pierre.


However on PublicationEvent...
-          The addition of the PublicationEvent, inheriting from the existing Event class. Two sorts of publication events are covered: broadcast events (to allow EPG events to be describe in a way understandable to search engines to fin content and services providing such content within a given area) and on demand events (NOTE: from an EBU and BBC perspective, such events are freely accessible. I may make sense to add the property 'free' as a Boolean to Event in order to differentiate free event from access controlled events and go form more complete on demand descriptions associated to transactional services.)

However such an Event specialisation could be also be used in a book/journal publishing context.  So the descriptive text, to prevent confusion for other event based extensions, could read something like:

a PublicationEvent corresponds indifferently to the event of publication for a CreativeWork of any type e.g. a broadcast
 event, an on-demand event, a book/journal publication, via a variety of delivery media

In which case I would suggest the 'free' boolean may well reside better at the inheriting class level.

~Richard.
