I think we are conflating 3 separate aspects here.

Firstly the relationship between a play, a production(s) of that play, and
individual performance(s) of a production.  I think the suggestion of using
CreativeWorkSeries “a group of related items, typically but not necessarily
of the same kind” is maybe leading us off at a tangent.  The series
approach is often used for things like The *Harry Potter series of movies*,
or the *For Dummies Book series*.   The production(s) of a play are not
normally a series they are different creative interpretations of the play.
  To that end I see a production as its own CreativeWork(play subtype) that
is an example of the original creative work (Play subtype).

A production is performed one or more times at individual performance
‘events’ these could possibly collected together into a season/run/festival
- an event with individual subEvents


Next we have the relationship between the Play/CreativeWork and other
creative works that contribute to, or are associated with, but not part of
the work - as per the example of stage notes.  Eric’s suggestion of using
‘mention’ or ‘about’ is a step in the right direction but I agree it does
not quite capture what is needed.  What if there was a ‘relatedWork’ or
‘associatedWork’ property available on CreativeWork?

Then there is the issue of how to describe the different types of
contributors/performers associated with a CreativeWork beyond the common
ones that already are defined, such as actor, author, director, composer,
etc.   In proposing a Play type there is the option to propose some play
relevant properties.  Director, choreographer, conductor, are potential
candidates but, in a generic vocabulary such as Schema.org, how far down
the production team list is it practical to go?  What about carpenter, wigs
mistress, chief electrician, etc.?

When you move beyond a few common jobs that might make sense to add to
Play, we need to look at using the Role <http://schema.org/Role> construct:

Play:
   > name: “The Tempest”
   > contributor: > Role:
                        > roleName: “Carpenter”
                        > contributor >  Person:
                                            > name: “Joe Soap”

For more on Role see The role of Role in Schema.org
<http://dataliberate.com/2015/04/15/the-role-of-role-in-schema-org/>.

So as to a proposal for Play oriented properties, we should constrain
ourselves to a few obvious ones, defaulting to using Role as we get further
down the credit list - as the Movie folks do.

Finally a question as to the narrowness of what is being
discussed/proposed.   Are we (or could we) covering other live show
possibilities?  Musical, Concert, Variety Show, Comedy Club Night, Cabaret,
Opera,  are all possibilities that come to mind.
