The IETF AI Preferences Design Team workshop
IPTC at the IETF AI Preferences Design Team workshop held in London in July 2025. The laptop screen shows the current public draft.

The IPTC participated in a “design team” workshop for the Internet Engineering Task Force (IETF)’s AI Preferences Working Group. Brendan Quinn, IPTC Managing Director attended the workshop in London along with representatives from Mozilla, Google, Microsoft, Cloudflare, Anthropic, Meta, Adobe, Common Crawl and more.

As per the group’s charter, “The AI Preferences Working Group will standardize building blocks that allow for the expression of preferences about how content is collected and processed for Artificial Intelligence (AI) model development, deployment, and use.” The intent is that this will take the form of an extension to the commonly-used Robots Exclusion Protocol (RFC9309). This document defines the way that web crawlers should interact with websites.

The idea is that the Robots Exclusion Protocol would specify how website owners would like content to be collected, and the AI Preferences specification defines the statements that rights-holders can use to express how they would like their content to be used.

The Design Team is discussing and iterating the group’s draft documents: the Vocabulary for Expressing AI Usage Preferences and the “attachment” definition document, Indicating Preferences Regarding Content Usage. The results of the discussions will be taken to the IETF plenary meeting in Madrid next week, and 

Discussions have been wide-ranging and include use cases for varying options of opt-in and opt-out, the ability to opt out of generative AI training but to allow search engine indexing, and the difference between preferences for training and preferences for how content can be used at inference time (also known as prompt time or query time, such as RAG or “grounding” use cases) and the varying mechanisms for attaching these preferences to content, i.e. a website’s robots.txt file, HTTP headers and embedded metadata.

The IPTC has already been looking at this area and defined a data mining usage vocabulary in conjunction with the PLUS Coalition in 2023. There is a possibility that our work will change to reflect the IETF agreed vocabulary.

The work also relates to IPTC’s recently-published guidance for publishers on opting out of Generative AI training. Hopefully we will be able to publish a much simpler version of this guidance in the future because of the work from the IETF.
