Hi Peter

A lot of interesting questions, not as academic as some would think :)
And not "corner cases", seems to me, Peter is just trying to figure out the
lines along which our concepts split the world.

Some thoughts (not addressing all Peter's questions, of course)

- The current model seems (for good reasons of mainstream usage) focused on
what makes certainly for 99% of online information about sports likely to
be marked with schema.org : popular sports competitions involving popular
teams, e.g., World Cup, Olympic Games, NBA, Tour de France etc. In that
sense, it's most of the time both athletic and competitive, often but not
always professional, but in all cases much structured in space and time by
organizations and events.

- The organizational aspect of sports is somehow orthogonal to competition.
Chess or Scrabble federations and competitions are organized basically
along the same model as soccer or basketball. Hence a model of teams and
competition should be independant of the level of physical engagement in
the activity. http://schema.org/PlayAction seems to be OK for all of those.

- OTOH some quite physical activities are (abusively maybe) called "sports"
even if they don't imply competition, such as training, fitness, yoga,
aikido ... and their organization may or may not be ruled by organizational
structures similar to sport federations, leagues etc. I practice and teach
aïkido in France in the framework of a national federation organized in
regional leagues composed of local clubs. There is no competition (aikido
spirit forbids it) but there are events such as training sessions under the
direction of (more or less famous) masters. And indeed, asking if aikido
clubs, leagues and events will be able to be use the sports schema can be a
good way to see where the line has been drawn.

If the model is able to keep orthogonal those different aspects ...
- organizational : clubs, teams, federations ...
- event : competitions, meetings, training sessions ...
- competition : results, records, decisions, ratings ...
- activity type : physical / athletic vs intellectual (chess) ...

... it will be able to capture not only the core 99%, but extend nicely to
"corner cases" :)
