{scheme}://{server}{/prefix}/{identifier}/info.json

Technical Property	Required?	Description
`@context`	Required	The context document that describes the semantics of the terms used in the document. This must be the URI: `http://iiif.io/api/image/2/context.json` for version 2.1 of the IIIF Image API. This document allows the response to be interpreted as RDF, using the JSON-LD serialization.
`@id`	Required	The base URI of the image as defined in URI Syntax, including scheme, server, prefix and identifier without a trailing slash.
`@type`	Optional	The type for the Image. If present, the value must be the string `iiif:Image`.
`protocol`	Required	The URI `http://iiif.io/api/image` which can be used to determine that the document describes an image service which is a version of the IIIF Image API.
`width`	Required	The width in pixels of the full image content, given as an integer.
`height`	Required	The height in pixels of the full image content, given as an integer.
`profile`	Required	A list of profiles, indicated by either a URI or an object describing the features supported. The first entry in the list must be a compliance level URI.
`sizes`	Optional	A set of height and width pairs the client should use in the `size` parameter to request complete images at different sizes that the server has available. This may be used to let a client know the sizes that are available when the server does not support requests for arbitrary sizes, or simply as a hint that requesting an image of this size may result in a faster response. A request constructed with the `w,h` syntax using these sizes must be supported by the server, even if arbitrary width and height are not.
`tiles`	Optional	A set of descriptions of the parameters to use to request regions of the image (tiles) that are efficient for the server to deliver. Each description gives a width, optionally a height for non-square tiles, and a set of scale factors at which tiles of those dimensions are available.
