 Processes that perform geo-spatial processing can be expected to have geometric and feature input types.  In JSON, geometries, features and collections of feature are commonly encoded using https://datatracker.ietf.org/doc/html/rfc7946[GeoJSON].  Rather the requiring processes descriptions to embed or reference the full schemas for https://datatracker.ietf.org/doc/html/rfc7946[GeoJSON] geometries, features or feature collections, this Standard defines a common set of convenience tokens that can be used instead.  
 
-The <<jsonschemavalidation,JSON Schema specification>> defines a https://json-schema.org/draft/2020-12/json-schema-validation.html#rfc.section.7[set of values] for the `format` key.  This Standard extends this list by defining the following additional key values for use specifically in OGC process descriptions for defining geometric, feature or feature collection inputs or outputs.
