I can’t see why we can’t create a simple tourism=outdoor_event pin at the location of the event and list it’s time in something like event=seasonal/ date / existing time mapping, and could use admin_level for scale - and use additional tags ina relation for larger events or micromapping.
we have huge city / regional summer festivals in Japan that are held in the same place on the same day every year (some on the same calandar date "august 1-3" or on the same “first friday-sunday in August”. It would be easy to map the boundary and location of amenities and the extent of closures of the roads for the events, as they haven’t changed in decades. A simple pin might be just fine for small seasonal outdoor events , mapping the extended details of the event should be expanded into a relation, such as a boarder of the known area (role=boundary), especially since for many outdoor events the areas and roads are “normal” most of the year. normally mapped Ways & areas could be tagged with outdoor_event:highway=pedestrian or outdoor_event:amenity=parking (or whatever it is during the event) to show their role during the event - yet be mapped normally the rest of the time - and added as regular members of the relation. this would interfere the least with existing mapping. the tag scheme outdoor_event:foo=bar could be used on new pins/ways/areas to map any other “permanent” items of the event (stages, pavillions, parking, toilets, paths, etc) that are normally not present. this would keep the “event” pobjects out of the regular map data until the event date could trigger the changed rendering if they wanted to support it. If renderers ignored that extended data, they could still render the tourism=event pin with the name of the event easily (and the boundary as well) - which would probably be enough for most events.
