First Public Working Note of the Web of Things Protocol Binding Templates; updated WoT drafts

5 April 2018

The Web of Things provides layered interoperability between Things by using the WoT Interfaces and enables applications to interact with and orchestrate connected Things at Web scale. The Web of Things (WoT) Working Group has published today:

• A First Public Working Group Note of the Web of Things (WoT) Protocol Binding Templates. This document describes the initial set of design pattern and vocabulary extensions to the WoT Thing Description. Protocol Binding Templates consist of reusable vocabulary and design pattern extensions to the WoT Thing Description format that enable an application client to interact, using a consistent interaction model, with Things that expose diverse protocols and protocol usage. See the specification to discover how to contribute to this draft.
• An updated Working Draft of the Web of Things (WoT) Thing Description. This specification describes a formal model and common representation for a Web of Things Thing Description, which describes the metadata and interfaces of Things, where a Thing is an abstraction of a physical entity that provides interactions to and participates in the Web of Things. In addition to physical entities, Things can also represent virtual entities. A Thing Description instance can be hosted by the Thing itself or hosted externally due to Thing’s resource restrictions (e.g. limited memory space) or when a Web of Things-compatible legacy device is retrofitted with a Thing Description.
• An updated Working Draft of the Web of Things (WoT) Scripting API. This specification describes a programming interface representing the WoT Interface that allows scripts run on a Thing to discover and consume (retrieve) other Things and to expose Things characterized by Properties, Actions and Events. Scripting is an optional “convenience” building block in WoT and it is typically used in gateways that are able to run a WoT Runtime and script management, providing a convenient way to extend WoT support to new types of endpoints and implement WoT applications like Thing Directory.
