But, apart from EEA, national federations follow a similar approach,
enabling filters on their calendars. For instance:
* ESP (international, national)
* IRL (international, national, provincial, county, club, open)
* FRA (international, regional, inter-regional, departamental, inter-clubs)
* CZE (foreign, national, regional…)

What you mention here is the *geographical location* of the venue, which is
currently described in [https://w3c.github.io/opentrack-cg/spec/model/#place].
There you can find the information you mention. See the example published
on the doc:
{
    "name": "Olympic Stadium Amsterdam",
    "geo": {
        "latitude": "52.343417",
        "longitude": "4.854192",
        "elevation": "123.93"
    },
    "map": "http://example.org/map",
    "address": {
        "streetAddress": "Olympisch Stadion 2",
        "addressLocality": "Amsterdam",
        "postalCode": "1076 DE",
        "addressCountry": "countrycode:NLD"
    }
}

As always, all the properties are optional, depending on the information we
manage.

Right. This is the purpose of the classification based on (international,
national, regional, etc.) proposed above.

There is a property "organizer" already (it could be a person or
organisation)

+1 -> I think this is what Nicolas called "label". Maybe an additional
property like 'licencedBy' or extending the one we already have,
'recognizingAuthority'.

This can be modeled with the types of competitions defined by the BBC
Ontology (KnockoutCompetition, Match, LeagueCompetition, etc.)

This is already included by the property 'url'.

This could be descriptive text.

There is already a field for this:
* 'entryRequirements'.- Requirements to take part in a competition.

Definitely, the most geo information we have, the better. We all know the
precision issues of geocoding when information is missing.

Best,
