This PR is a **documentation change only**. It documents the fact that `name:xx` values are present in the tiles and documents that `name_de` and `name_en` will be removed in a future release in favor of `name:de` and `name:en` respectively.

The park layer in OpenMapTiles contains natural and protected areas from OpenStreetMap,
|
|
such as parks tagged with [`boundary=national_park`](https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dnational_park),
|
|
[`boundary=protected_area`](https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dprotected_area),
|
|
or [`leisure=nature_reserve`](https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dnature_reserve).
|
|
This layer also includes boundaries for indigenous lands tagged with
|
|
[`boundary=aboriginal_lands`](https://wiki.openstreetmap.org/wiki/Tag:boundary%3Daboriginal_lands).
|
|
Indigenous boundaries are not parks, but they are included in this layer for technical reasons related to data processing.
|
|
These boundaries represent areas with special legal and administrative status for indigenous peoples.

Use the **class** to differentiate between different kinds of features in the `parks` layer, for example between parks and non-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=aboriginal_lands` is `aboriginal_lands`.
|
|
name: The OSM [`name`](http://wiki.openstreetmap.org/wiki/Key:name) value of the park (point features only). Language-specific values are in `name:xx`.
|
|
name_en: English name `name:en` if available, otherwise `name` (point features only). This is deprecated and will be removed in a future release in favor of `name:en`.
|
|
name_de: German name `name:de` if available, otherwise `name` or `name:en` (point features only). This is deprecated and will be removed in a future release in favor of `name:de`.
|
|
rank: Rank of the park within one tile, starting at 1 that is the most important park (point features only).
