!!! Overview
[{$pagename}] is defined within [RFC 6902].

[JavaScript Object Notation] ([JSON]) [RFC 4627] is a common format for the exchange and storage of structured data.

[HTTP PATCH] [RFC 5789] extends the Hypertext Transfer Protocol ([HTTP]) [RFC 2616] with a method to perform partial modifications to resources.

[{$pagename}] is a format (identified by the media type "application/json-patch+json") for expressing a sequence of operations to apply to a target [JSON] document; it is suitable for use with the [HTTP PATCH] method.

This format is also potentially useful in other cases in which it is necessary to make partial updates to a [JSON] document or to a data structure that has similar constraints (i.e., they can be serialized as an object or an array using the [JSON] grammar).
