Use the **class** to differentiate between different parks.
The class for `boundary=protected_area` parks is the lower-case of the
[`protection_title`](http://wiki.openstreetmap.org/wiki/key:protection_title)
value with blanks replaced by `_`.
`national_park` is the class of `protection_title=National Park` and `boundary=national_park`.
`nature_reserve` is the class of `protection_title=Nature Reserve` and `leisure=nature_reserve`.
The class for other [`protection_title`](http://wiki.openstreetmap.org/wiki/key:protection_title)
values is similarly assigned.
The class for `boundary=protected_area` parks is one of: `national_park`, `nature_reserve`, `recreation_ground`, or `historic`.
name: The OSM [`name`](http://wiki.openstreetmap.org/wiki/Key:name) value of the park (point features only).
name_en: English name `name:en` if available, otherwise `name` (point features only).
name_de: German name `name:de` if available, otherwise `name` or `name:en` (point features only).
