Type Messages

Types are defined using the JSON Schema specification (http://json-schema.org/). For details on supported property data types and formats, see Type Properties and Formats.

Types can be created, updated, or deleted. Updating a Type without updating the Type’s version will result in a failure. Once a Type is deleted, any operations on Containers or Data using that Type will fail.

The body of a Type message consists of an array of objects. The following keywords are used to define a Type:

Name Value
id Unique identifier of the Type.
classification One of dynamic or static.
version Optional version of the Type. If omitted version is assumed.
name Optional friendly name for the Type.
description Optional description for the Type.
tags Optional array of strings to tag the Type.
metadata Optional key-value pairs associated with the Type.
properties Key-value pairs defining the properties of the Type.
type Inherited from JSON Schema. Must be set to object.

The id cannot begin with the character sequence __. This is reserved for predefined Types. One currently supported predefined Type is __Link.

A static classification represents metadata describing a device being observed and should be used to capture data that is descriptive and relatively unchanging. A dynamic classification represents observed or calculated measurements taken from a device.
