crs.wkt name confusing

[rouault]

The mention of "wkt" in the crs.yaml in

ogcapi-tiles/openapi/schemas/common-geodata/crs.yaml

Line 15 in dabbe22

- wkt

is very confusing.
The description mentions "An object defining the CRS using the JSON encoding for Well-known text representation of coordinate reference systems 2.0". JSON != WKT . WKT CRS is a well established naming for things like GEOGCS[], GEOGCRS[], PROJCS[], etc. Definitely not appropriate for any JSON encoding, be it PROJJSON or a so-called "improved" version of it

@rouault I wholeheartedly agree.

Although it sits in this common-geodata directory, this is actually only for 2DTMS & TSMD.

Perhaps in a minor revision we could deprecate this wkt and add projjson or crsjson, and perhaps add wkt2crs as well?

In any case, it is much more preferable (and interoperable) to use a registered CRS and use the uri field instead, if at all possible.
