Jason,

Thanks for putting this together. Here are my remarks:

SportsOrganization has a property of sport. This might be better as
discipline.
If Rugby is a sport, then Rugby League and Union might be disciplines.

Statistic has thingMeasured and measuredValue. I wonder if we need a unit
here too.
Exploring the Heptathlon event might be an idea here, as this has tripped
us up in the past.

I think we're missing an attempt at modelling seasons. Here is an example
of how we model seasons, using the notion of a Recurring Competition:

I've also attempted to try and answer some of Peter's queries in line.

Best,

Tom

I'm not sure Sports are professional or otherwise. I can be a professional
athlete and be paid for playing Football, or I might choose to play it
with friends at the park. And not be paid.

Competitions might be professional or otherwise however.

I admit this is awkward. Skiing is also a mode of transport. I think there
might be Skiing the locomotive activity, the leisure activity and the
competitive sport activity.

Today I consider Sport to be athletic. Chess is a competitive activity,
but may be played by a machine.
Motor Racing, Darts and Shooting are not athletic in the sense of
Football, but all involve elements of endurance, skill, accuracy etc which
are properties of the animal body over time.

Again, awkward. We avoid the issue in the Sport ontology by only modelling
disciplines and sub disciplines:

In the sense that coaches, physios, managers are part of a team - every
sport is a team sport. Sometimes we refer to head to head sports. Perhaps
that doesn't help.
We deal with this problem in the Sport ontology like so:

Being Home or Away is a property of the event and not necessarily anything
to do with to location. Data is published today about the World Cup
matches where neither team has an affiliation with the stadium, but either
one is designated as either home or away.

Difficult. We are modelling Cricket now and I admit I am not yet familiar.
Cricket does appear to have it's own sense of Ties and Draws.

I would hope we can use a dbpedia identifier here. Public URIs might be
useful for merging data.
