FPWD Request for Web of Things (WoT) Thing Description 2.0 - wot-thing-description-2.0 from https://github.com/w3c/transitions/issues/738 # Document title, URLs, estimated publication date Title: Web of Things (WoT) Thing Description 2.0 Editor's Draft URL: https://w3c.github.io/wot-thing-description/# Estimated Publication Date: September 23, 2025 # Abstract This document describes a formal information model and a common representation for a Web of Things (WoT) Thing Description (TD), Version 2.0. A Thing Description describes the metadata and interfaces of [Things](https://w3c.github.io/wot-thing-description/#dfn-thing), where a [Thing](https://w3c.github.io/wot-thing-description/#dfn-thing) is an abstraction of a physical or virtual entity that provides interactions to and participates in the Web of Things. Thing Descriptions provide a set of interactions based on a small vocabulary that makes it possible both to integrate diverse devices and to allow diverse applications to interoperate. Thing Descriptions, by default, are encoded in a JSON format that also allows JSON-LD processing. The latter provides a powerful foundation to represent knowledge about [Things](https://w3c.github.io/wot-thing-description/#dfn-thing) in a machine-understandable way. A Thing Description instance can be hosted by the [Thing](https://w3c.github.io/wot-thing-description/#dfn-thing) itself or hosted externally when a [Thing](https://w3c.github.io/wot-thing-description/#dfn-thing) has resource restrictions (e.g., limited memory space) or when a Web of Things-compatible legacy device is retrofitted with a Thing Description. Furthermore, this document introduces the Thing Model, which allows authors to describe only the model or class of an Internet of Things (IoT) entity. Thing Models can be seen as a template for Thing Description instances, but with reduced constraints such as no or few requirements for specific communication metadata. This specification continues the work of [[WOT-THING-DESCRIPTION11](https://w3c.github.io/wot-thing-description/#bib-wot-thing-description11)] with no guarantees on backwards compatibility. In case of no backwards compatibility, there will be concrete guidelines for implementers to migrate to the new version. # Status https://w3c.github.io/wot-thing-description/#sotd # Is it a delta specification intended to become a W3C Recommendation? Yes # Link to group's decision to request transition https://www.w3.org/2025/09/03-wot-minutes.html#3d2c # Issues https://github.com/w3c/wot-thing-description/issues # Information about implementations known to the Working Group TD 1.1 implementations: https://www.w3.org/WoT/developers/ and https://w3c.github.io/wot-thing-description/testing/report11.html NOTE: For more information, see [Organize a Technical Report Transition](https://www.w3.org/guide/transitions/?profile=FPWD). -- This email was generated automatically using https://github.com/w3c/transition-issues-bot
