The WoT Thing Description task force is responsible for defining the information model for WoT Thing metadata, its interpretation, and its common representation. In addition, the task force covers WoT Binding Templates topics to define the mapping from the abstract interaction model used in the Thing Description metadata to concrete IoT protocols and payload encodings.
This document describes a superset of the features defined for Thing Description 1.0. In general, this document describes the formal model of a Thing and its common representation in JSON-LD 1.1. It introduces a simple interaction model with Properties, Actions, and Events to describe the capabilities of a Thing, including its data model, communication protocols used, security mechanisms, and other semantic metadata. A WoT Thing Description defines a specific instance of a Thing. The WoT Thing Description 1.1 also formally introduces the Thing Model concept that describes sets of Things. It has fewer restrictions than the Thing Description and does not contain any instance-specific information.
This document describes a set of vocabulary extensions to the WoT Thing Description that make up the Binding Templates. Binding Templates enable a Thing Description to be adapted to specific protocol or data payload usages across different standards. This is done through additional descriptive vocabulary that is used in the Thing Description.
