6.1 General

The WoT specification defines both a TD and a Protocol Binding.

The WoT TD is defined here:

https://www.w3.org/TR/wot-thing-description/#introduction-td

The WoT Protocol Binding is defined here:

https://www.w3.org/TR/wot-binding-templates/#binding-overview

The goal of this Companion Specification is to create a thin interface for configuring industrial connectivity software in a standardized way. By keeping the interface to a minimum, the chances of adoption by the industry are increased.
