I just came across <https://www.openstreetmap.org/way/161362655> an agricultural showground tagged as leisure=park and realised I didn't know what a sensible way to retag it would be. Although there are a limited number in the UK (perhaps 100 or so) they do tend to be quite prominent and when major events take place at them (e.g., Scout Jamborees, National Eisteddfod) good tagging can be useful. I recall Richard Bullock mapping the Royal Cheshire quite a few years ago as it helped parents pick up their children after the scout Jamboree.
Various (inconsistent) approaches have been used: * Newark <https://www.openstreetmap.org/way/178396540> & Norfolk <https://www.openstreetmap.org/way/40942963> mapped as tourism=attraction * Rutland <https://www.openstreetmap.org/way/547075306> as leisure=recreation_ground (there are certainly sports pitches here out of events) * Royal Cheshire <https://www.openstreetmap.org/way/67375462> as amenity=showground with landuse=grass. It strikes me that how grounds are a special type of events venue and perhaps rather than using amenity=showground it may be better to use amenity=events_venue with a subtag events_venue=showground. leisure & tourism tags may still be applicable, and landuse=grass can still be (mis-) used to show the area (see Newark & Royal Cheshire). Alternatives might be amenity=exhibition_centre, but this seems more for places like the NEC. The current wiki description circumscribes events venues fairly closely, so this would be an extension in meaning. I don't think anything in the UK (or Europe) is quite on the scale of the Minnesota State Fair <https://www.openstreetmap.org/way/39662664> which certainly merits tourism=attraction.
