A proposed extensions mechanism for GeoJSON

Extensions Object

A GeoJSON object MAY contain a member named Extensions which is an extensions object. An extensions object SHALL contain a set of key/value pairs describing the extensions in use in that GeoJSON object.


The key is a machine-readable string that names the extension. A key SHOULD have a prefix that names the community responsible for naming the extension. A GeoJSON object SHOULD contain an extensions object to declare which extensions are in use. If a client supports one or more GeoJSON extensions, it SHOULD inspect the extensions object.


The value is a human-readable string describing the extension.
