  You just said it was based on "you treating it like one." How is that not subjective? Your assertion that becaue you can recreationally walk down a path you've never been on that it makes it a park is completely subjective also. 
  
  You haven't shown any nexus. Except a single unreliable source that isn't backed up by anything in OSM or it's definition of a park...Soo...You said so yourself you haven't even been there or walked down the path. Just go do it and map it with mappilary. It's not that hard. 
  
  "It is an open space. USLegal (.com, go find your own that agrees with your confused understanding)"
  
  I'm pretty sure that OSM tagging isn't based on the single legal definition of something in one country. Just like someone can't violate copyright laws in OSM because they live somewhere that doesn't have any. 
  
  Either way, just like I said above if you go with open space as being "Open space is any open piece of land that is undeveloped (has no buildings or other built structures) and is accessible to the public" it's still so broad a definition as to make the tag useless. So I'm sure that's not what the wiki means by open space. Its obvious it's more in the meaning of a "space that's open." There's still the whole "managed greenery" thing also. Which you conveniently ignored. I think your the one confused into thinking an individual countries laws dictates how things are tagged in OSM. it's 100% clear they don't. Otherwise, show me a source to support it with. 
  
  "Nobody "gets the cops called on them" for being on open space, unless that open space is specifically closed to public access (some are)." 
  
  Really? No body? It happens to black people all the time. There was just a case last summer of a black person that got the cops called on them for barbecuing in a park.
