Re: Scores for head to head events

I was wondering if we could make use of the Action concept for representing head to head actions/results. Schema.org already has the concept of WinAction, TieAction and LoseAction. In this case, a football WinAction could be modelled as:

<!--  Liverpool won a football competition against Crystal Palace. -->
<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "WinAction",
  "agent": {
    "@type": "SportsTeam",
    "name": "Liverpool",
    "@id": "https://dbpedia.org/resource/Liverpool_F.C."
  },
  "object": {
   "@type": "SportsEvent",
    "name": "Barclays Premier League Liverpool v Crystal Palace"
  },
 "result": "2-0",
 "agentScore": 2,
  "participantScore": 0,
  "participant": {
    "@type": "SportsTeam",
    "name": "Crystal Palace",
    "@id": "https://dbpedia.org/resource/Crystal_Palace_F.C."
  }
}
</script>

The Action concept has the general https://schema.org/result  predicate, which can be used within any Action. A SportsResult could be defined within that context.

Cheers,

For info and not intended to sway the conversation in any particular direction:

home/awayCompetitor lifts from the Sport ontology:

http://www.bbc.co.uk/ontologies/sport#terms_awayCompetitor<http://www.bbc.co.uk/ontologies/sport#terms_homeCompetitor>

There’s a gist I did a while ago here:

Scoring gets hard when scores can be applied variously to events and/or competitors, we got stuck on this last time.

Hi folks:

SportsEvent also supports the SportsEvent-->competitor relationship, where competitor can be SportsTeam or Person. Oddly enough this seems to be the way homeTeam and awayTeam are also mapped which seems confusing (they can be Persons?)

Perhaps homeTeam and awayTeam should be refactored out and replaced by the competitor relationship, where cardinality is enforced by subtypes (e.g., if SportsEvent is a FootballGame, competitor max cardinality is 2 and competitor types are restricted to Team).

For results I think a CompetitorResult object may be required (or CompetitorScore [subclass?]) that is then applied to the Event object.

Of course the issue of tracking how the CompetitorScore might change over time is also a consideration.

Also, how general do we need to be? Are we going to draw a distinction between team events, head-to-head sports (boxing, fencing) and race-type events (F1, athletics, swimming)? Or do we want a general formation for all three of those types of competition (to use the north american sense of that word :)

This is the crux of the issue. To support events with more than two competitors, we will need more than a simple homeScore/awayScore model. With the Olympics coming up again, I think we should consider supporting these events sooner rather than later.
