[OSM-talk] Historic Mapping needs help Now!

[Stephen Hope]

I am hoping in a couple of weeks to map the grounds at a festival that
occurs yearly in the same spot. This is not so much historical data,
as data that's only true for three weeks a year. The rest of the time,
it's just fields, with a few items (some toilets, etc) that stay in
place year round.

Would this come under historical mapping, or some other tagging scheme?
