W3C and GS1 open call for e-commerce AI agents workshop in Zurich

The World Large Internet Consortium this week announced a joint workshop with GS1 on the way forward for e-commerce in a world the place AI brokers more and more sit between internet content material and the top customers who devour it. The occasion, titled “E-commerce for People and AI Brokers,” is scheduled for September 8 and 9, 2026, in Zurich, Switzerland, with distant participation obtainable. Google is internet hosting the occasion.

The announcement, revealed June 1, 2026 on the W3C web site, opens a proper name for participation with a submission deadline of June 26, 2026.

What the workshop is about

In accordance with W3C, internet content material has traditionally been designed for people, even when pages additionally expose structured knowledge by way of APIs or embedded JSON-LD utilizing vocabularies corresponding to schema.org and the GS1 Internet Vocabulary. That mannequin is below strain. Giant language fashions and AI brokers have gotten a brand new middleman between that content material and finish customers – summarizing search outcomes, following hyperlinks, and doubtlessly supporting customers in on-line exercise earlier than an individual ever visits a web page straight.

The core query the workshop units out to look at is what this shift means for the individuals and organizations that create, curate, and publish internet content material. In accordance with W3C, the occasion goals to share experiences of making content material with AI brokers in thoughts, focusing particularly on e-commerce. What practices are only? What are the pitfalls? What changes do content material creators must make to maximise the return on funding in time, vitality, and talent?

The impetus is industrial. E-commerce is the actual focus, although the organizers count on the dialogue to attract on broader views associated to content material creation and publication typically.

The technical backdrop: MCP, UCP, and ACP

Three protocols sit on the middle of the technical dialog the workshop will tackle: MCP (Mannequin Context Protocol), UCP (Common Communication Protocol), and ACP (Agent Communication Protocol). In accordance with W3C, the workshop asks what practices assist retailers, manufacturers, content material creators, curators, LLM and AI agent suppliers, web optimization practitioners, and on-line knowledge suppliers stay seen and helpful by way of these protocols, whereas maintaining the net really open moderately than forcing content material creators into closed or semi-closed ecosystems.

MCP has grow to be a dominant technical sample for connecting AI brokers to exterior knowledge sources and platforms. Anthropic introduced MCP as an open standard in November 2024, and adoption throughout the advertising and marketing expertise sector accelerated sharply all through 2025 and into 2026. Amazon opened its advertising APIs through MCP in February 2026, and Google proposed WebMCP at I/O 2026 in May as a browser-level open internet normal that enables builders to show structured instruments – JavaScript capabilities and HTML kinds – so browser-based AI brokers can execute advanced duties with out counting on screenshot parsing and DOM manipulation.

Chrome 149 subsequently opened a WebMCP origin trial, a primary concrete schedule hooked up to what had beforehand been a proposed normal. That trial is related context for the September workshop: the infrastructure questions W3C and GS1 wish to look at are usually not hypothetical. A number of of the protocols below dialogue are already in lively improvement or restricted deployment, and the industrial stakes for retailers and types are rising.

The W3C’s curiosity on this area shouldn’t be new. In February 2026, it held a three-day digital Workshop on Good Voice Brokers, which recognized eight unresolved requirements gaps protecting interoperability, privateness, hallucination management, and accessibility. The official report, published on March 31, 2026, mapped a roadmap of work that W3C Group Teams, upcoming occasions, and a potential new W3C exercise may take ahead. The September e-commerce workshop extends that sample of utilizing convened occasions to map an rising requirements territory.

The JSON-LD and schema.org context

The structured knowledge layer the workshop references – significantly JSON-LD utilizing schema.org vocabulary and the GS1 Internet Vocabulary – has existed for years. Schema.org was launched in 2011 by Google, Bing, Yahoo, and later Yandex to create a typical set of schemas for structured knowledge markup on internet pages. Greater than 10 million web sites use schema.org markup. The GS1 Internet Vocabulary, maintained by the identical GS1 group co-hosting this workshop, extends schema.org particularly for product-level industrial knowledge.

The problem the workshop addresses is that this infrastructure was constructed for a unique discovery surroundings. Search engines like google and yahoo crawled pages, learn structured knowledge, and introduced outcomes to human customers who then clicked by way of. AI brokers change that sequence. They could learn structured knowledge and by no means ship a consumer to the web page in any respect, or they might act on product info with out the form of referral site visitors that structured knowledge was initially designed to generate.

Google’s Gary Illyes highlighted related infrastructure fragility in analysis published by PPC Land in June 2026, noting that the net’s reliance on JavaScript-heavy pages creates vital issues for AI brokers trying to extract structured info. Server-side rendering, semantic HTML, and clear doc construction – technical web optimization fundamentals – have taken on new significance because the methods consuming internet content material multiply and diversify.

For e-commerce particularly, the implications are direct. PPC Land reported in May 2026 that Google flagged eight specific Merchant Center feed attributes required for visibility in AI Mode and AI Overviews, with exact character limits and documented formatting errors that break knowledge ingestion. That form of attribute-level specification is strictly the territory the W3C and GS1 workshop desires to look at systematically.

Who can take part

In accordance with W3C, attendance is free for invited individuals and is open to individuals who can contribute related expertise, use instances, technical views, implementation expertise, analysis findings, or standardization questions. The organizers goal for various participation throughout 5 particular communities: content material creators and curators of all types; LLM and AI agent suppliers, together with in-browser AI brokers; manufacturers making merchandise to promote, and retailers promoting them; SEO practitioners; and on-line knowledge suppliers.

Two participation pathways exist. A Place Assertion is suitable for individuals who wish to counsel a subject, share a perspective, or be thought-about for a presentation, panel, demonstration, or breakout dialogue. An Expression of Curiosity is suitable for individuals who wish to attend and contribute to dialogue however wouldn’t have a particular matter to suggest.

In accordance with W3C, a great place assertion needs to be a number of paragraphs lengthy. It ought to embrace the submitter’s background in the principle matter areas, what they wish to contribute or talk about, how their contribution pertains to e-commerce for people and AI brokers, related use instances or standardization gaps, and hyperlinks to associated supporting sources if obtainable.

Submissions might be made by way of GitHub – utilizing both the Place Assertion template or the Expression of Curiosity template – or by electronic mail to [email protected]. For electronic mail submissions, the topic line ought to comply with the format “[Position Statement] – Your Identify / Group” or “[Expression of Interest] – Your Identify / Group.” Submitters ought to point out whether or not they favor to attend in individual or remotely, to assist organizers plan venue capability and distant participation help.

The deadline for each sorts of submission is June 26, 2026. Acceptance notifications will exit on August 1, 2026. An preliminary agenda shall be revealed on August 17, 2026.

The Programme Committee

The workshop’s Programme Committee consists of representatives from a notable vary of organizations. Phil Archer from GS1 serves as co-chair, alongside a second chair listed as TBD. Committee members symbolize a broad cross-section of the industrial and technical internet: Mark van Berkel from Schema App, Trish Burgess from Airbnb, Jean-Luc Di Manno from Fime, Wei Ding from Huawei, Anssi Kostiainen from Intel, Alex Jansen and Michael Linck from Google, Natalia Macia from Bosch, Gavin Shenker from Visa, Andrew Smith and Riley Sturdy from OpenAI, Vasilii Trofimchuk from Block Inc., Andrea Volpini from WordLift, and Léonie Watson from Tetralogical. An extra committee member is listed as TBD.

The presence of OpenAI representatives alongside Google personnel on the identical programme committee is notable. Each organizations are creating AI methods that work together with internet content material at scale, and each have industrial pursuits in how the requirements that govern that interplay evolve. Visa and Block Inc. add a payments-layer perspective to discussions that may inevitably contact on checkout flows and transaction knowledge. Airbnb and Bosch symbolize large-scale product and stock publishers with structured knowledge operations on the industrial finish of the market.

Why this issues for advertising and marketing and promoting

The workshop sits on the intersection of a number of forces which were reshaping digital promoting and search advertising and marketing all through 2025 and 2026. The shift towards AI-mediated discovery – the place a consumer asks a query and an agent assembles a solution from a number of sources moderately than presenting a listing of hyperlinks – modifications the visibility economics that digital advertising and marketing has operated on for twenty years.

Skepticism about the commercial viability of AI shopping agents has been documented since at least October 2025, with analysts figuring out structural challenges together with retailer incentives in opposition to AI intermediation and excessive e-commerce return charges. Amazon and Shopify – which collectively management greater than 50% of the US e-commerce market – have reportedly blocked AI brokers to take care of discovery possession and defend retail media companies. The W3C workshop doesn’t resolve these industrial tensions, but it surely gives a venue the place technical requirements work can proceed in a means that at the very least acknowledges them.

The requirements that emerge from processes like this one have very long time horizons. The W3C updated its own Process Document in August 2025 to streamline how requirements advance by way of the event pipeline – eradicating the Proposed Advice section and introducing Constitution Refinement – however even a simplified requirements course of operates on a timescale of years. The September 2026 workshop is positioned as a scoping and alignment occasion, figuring out shared questions and standardization alternatives moderately than producing completed specs.

For web optimization practitioners and e-commerce operators, the sensible implication is that the infrastructure choices made in 2026 – how product knowledge is structured, which vocabularies are used, how pages expose their performance to brokers – will form visibility in agent-mediated discovery for years to come back. The workshop presents a channel to affect how these requirements are outlined.
