Open Errata for the Web of Things (WoT) Thing Description 1.1 Specification
Open Errata for the Web of Things (WoT) Thing Description 1.1 Specification
- Latest errata update:
- 12 March 2025
- Number of recorded errata:
- 4
How to Submit an Erratum?
Errata are introduced and stored in the issue list for the WoT Thing Description GitHub repository. The workflow to add a new erratum is as follows:
-
A possible mistake is submitted as issues on GitHub, whose title MUST start
with
[POSSIBLE ERRATA]
, e.g.[POSSIBLE ERRATA] This sentence is wrong
. Anyone can submit the issue. The specification version MAY be indicated in the issue description. - The issue MUST be evaluated before it becomes an official errata, which is reserved for mistakes, errors and bugs in the REC document.
-
Evaluation of the label MUST happen by the Thing Description Task Force of the Web of Things Working Group.
- If this Task Force is not active anymore, the Web of Things Working Group MUST evaluate it.
- If the Web of Things Working Group does not exist anymore, the W3C Team or their delegated entity MUST evaluate the submission.
-
Evaluation result MUST be adding a GitHub label with text being either
Official Substantive Errata TD1.1 Confirmed
orOfficial Editorial Errata TD1.1 Confirmed
. Note that whether the errata is substantive or editorial depends on the errata. If there is implementation impact, it is generally a substantive errata. -
If a GitHub issue is submitted without thinking that it can be Errata, thus not contain
[POSSIBLE ERRATA]
but turns out to be one, it CAN also obtain the label above after an evaluation by the Thing Description Task Force of the Web of Things Working Group. Note that the delegation of the Task Force is NOT REQUIRED to evaluate every new issue. -
The Thing Description Task Force of the Web of Things Working Group or the delegation edits the REC document to
address the errata with a GitHub Pull Request also containing
the label
Official Errata Fix
. In the same Pull Request, the Task Force or the delegation edits the corresponding errata.html document manually based on the issue, following the instructions below in this document. - Resolution to merge the Pull Request MUST be a Web of Things Working Group resolution or a mechanism chosen by the delegation.
If you have problems following this process, but you want nevertheless to report an error, you can also contact the staff contact of the Web of Things Working Group, Kaz Ashimura.

Substantive Issues
Editorial Issues
- 2025-03-12: In the Thing
Description JSON Schema and its associated TM Validation Schema, the term
@context
was allowing adding maps (JSON objects) where the name-value pairs could contain a non-string value. Such JSON documents would be invalid JSON-LD documents, which TD users should not create. As this only effects the resources, WoT TD 1.1. HTML specification is not affected. This is fixed in the Pull Request 2080. - 2024-04-24: In the Thing
Description ontology and it's associated HTML page, the term
hasConfigurationInstance
has been changed tohasInstanceConfiguration
to match the JSON-LD context file. This change does not affect the WoT TD 1.1. HTML specification. - 2024-04-24: In the Thing
Description
ontology and it's associated HTML
page,
the
domain
of classesmodel
andinstance
has been changed toversionInfo
to match the TD specification. This change does not affect the WoT TD 1.1. HTML specification. - 2024-05-06: In the HTML pages of the ontologies (TD, JSON Schema, Security, Hypermedia Controls, TM, the links to the corresponding Turtle files were wrong. Links are now corrected and the content negotiation mechanism to get correct files is explained. This change does not affect the WoT TD 1.1. HTML specification.
