Content Type

Definition

Devices can send Messages to the Deployment Instance in a wide variety of formats. NuvIoT categorized these formats as the Content Type of the Message. A Parser is then needed to extract values from the Message and convert them into a common format that will be used within NuvIoT.

Example

The Plymouth IoT Conveyor Belt sent a Message that contained a JSON payload (human read-able text) of 425°. A Parser had been created in the belt’s Deployment Instance to extract the temperature out of that JSON payload and convert it to a real number that could be used by the Workflow.
