OpenStreetMap
Hello folks,
I've just been adding a few recreational areas to Copenhagen - several of these places are squares with multiple functions, like soccer/basketball/hockey or skateboarding/basketball etc.
I've read about semi-colon value separation and I get the point about choosing the primary function of a given area, but some of these areas are totally a blend.
So should this be a case to use the semi-colons or are there any better ideas?
Keep on mapping!

I have seen tags like sport=10pin;9pin;tennis;squash
or sport=swimming;gymnastics
but I don't like it.
At first try to separate fields. Afaik you can't play tennis and squash on/in the same court. Same for swimming and gymnastics unless it's underwater gymnastics.
Then focus on main activities. You can play poker on a tennis court, but normally you won't.
If there are many sports possible, use sport=multi.
If you still need multiple sports, tag separate nodes. Maybe the area with sport=soccer and a node with sport=hockey.

You should try to tag individual fields/pitches/tracks etc. to reduce the number of sports values per object. So far, I agree with wieland.
When there is still a small, but > 1 number of "primary" uses, however, then I suggest to prefer semicolons over "multi". After all, the worst case is the same as with sport=multi: An application doesn't know which sports the object is used for. But the best case with semicolons is that an application can evaluate the value list just fine. With sport=multi, even the best case is that you don't know which sports the objects is used for.

An alternative would be to tag
sport=soccer and sport:basketball=yes and sport:hockey=yes
But I havn't seen this so far in the DB and not in the wiki.
Similar to
fuel:diesel=yes
fuel:octane_91=yes
fuel:octane_95=yes
fuel:octane_98=yes
fuel:lpg=yes
See osm.wiki/Fuel
In osm.wiki/Sport
"several sports ... separated by semicolons"
are allowed.
