Hi Dan, all,

Some questions:
* 
>In Series:
>Rename 'episodes' into 'episode' (object is a single Episode with a position, not a list - confusing in the current spec)
>Rename 'seasons' into 'season'
>
>In Season:
>Rename 'episodes' to 'episode'

Could you explain why should we rename these properties? As far as I understand it may be several seasons in series and several episodes in series and season as well? Am I mistaken?

* 
>Add Thing > CreativeWork > Programme

Don't we want to add some special properties for programme? Smth like anchorperson, duration, ...

* Add Thing > CreativeWork > Clip

The same question. Can we add some specific properties for Clip type?

* > Add Thing > TimePeriod

What is TimePeriod? I mean is it smth more than mere ISO 8601 Time Intervals (http://en.wikipedia.org/wiki/ISO_8601#Time_intervals)?

* > Add 'broadcastOf' property, range 'Clip' or 'Episode', (JP) or Programme (also rename broadcastOf in 'source')

Agree with renaming.

* 
> Add Thing > Event > Broadcast
> Add 'broadcastOn' property, range 'Service'
> Add 'broadcastOf' property, range 'Clip' or 'Episode', (JP) or Programme (also rename broadcastOf in 'source')
> Add 'start', range date
> Add 'end', range date

What is the semantic of new 'start' and 'end' properties? We already have 'startDate' and 'endDate' in Event and 'period' property in Service. What is the difference from them?

* > Add contentTimePeriod, range 'TimePeriod'

The same question. Is it different from 'period' property of 'broadcastOn' (Service)?

In Series/Season:

[[[
Modify 'endDate' description to be 'start of the last first publication of an episode within that series/season'
]]]

"last first publication"? Perhaps just "last publication".

Regarding moving TVSeries (for example) under Series. Do you expect to publish schema:TVSeries rdfs:subClassOf schema:Series? This is really a broad question for all hierarchical classes.

Also, is it expected that the range of schema:episode is an rdf:List? How about an OWL restriction on the cardinality of schema:episode? What is the strategy for indicating that some properties really relate to an ordered collection? This was suggested in the Microdata to RDF mapping for the following properties as well [1]:

blogPosts, breadcrumb, episodes, events, itemListElement, musicGroupMember, seasons, ...

Really, just an example for how to treat properties that should take an RDF Collection, as this is the data-model that the microdata JSON encoding would take.
