TPAC is the most important W3C community event of the year. During this exciting week, W3C working and interest groups gather and network to resolve the challenging technical and social issues that the web faces.
TPAC 2026 is hybrid with the main in-person hub in Dublin Ireland.
The Hackathon is an informal evening event where in-person TPAC attendees collaborate, experiment, and build ideas that advance the web. As a friendly competition, it provides an opportunity to create, innovate, and showcase ideas in a relaxed, fun, and welcoming setting.
This is a plenary session that brings together all TPAC participants to share and develop a common vision of the challenges and priorities shaping the future of the web. It aims to foster dialogue and collaboration across W3C's communities.
Attendance is open to all TPAC participants.
Recent regulations restricting children's online access through age assurance requirements are driving major changes across the web, prompting a mini-workshop to continue discussions from last year's joint IAB/W3C workshop on age-based access restrictions. Attendees are encouraged to submit proposals for discussion topics such as privacy expectations, risk mapping, and the need for multi-stakeholder collaboration beyond purely technical solutions.
This mini-workshop will explore the positive and negative impacts of Generative AI on society and its intersection with W3C's Ethical Web Principles and Vision. TPAC attendees are encouraged to submit proposals for discussion topics such as sustainability, the open web, discoverability, inclusion, bias, neighbourhoods, accessibility, epistemic injustice, UI, translations, threat modelling, and co-browsing experiences.
To indicate interest in presenting about the positive or negative impact of GenAI on society:
The World Wide Web has shifted from its original open, sharing-focused vision. There are growing concerns over protecting vulnerable populations, managing copyright and AI data usage, and navigating centralised social media platforms that obscure data sharing and provenance. This workshop aims to explore new forms of data governance, data ownership, and decentralised alternatives. Attendees are encouraged to submit proposals for discussion topics such as user-centric alternatives, usage preferences, data provenance, and the role of web standards in balancing openness and ownership.
