W3C Breakouts Day 2026 (Calendar)

This breakout will demonstrate an interactive tool for exploring decision spaces and making trade-offs between design alternatives visible. The tool lets users map interconnected choices and highlight issues as decisions evolve, and suggests optimal design combinations based on defined priorities. We'll walk through how the tool works using a standards example (originally tried for one of the TC39 proposals). We'll discuss how the tool could potentially help W3C groups compare options, structure discussions, and move complex proposals forward with more clarity. The session focuses on hands-on demonstration and open discussion around practical use in W3C work.

Goal(s):
Demonstrate an interactive decision-support tool and explore whether it could help W3C groups structure discussions and compare design alternatives.

Agenda

  1. Welcome and introduction.
  2. Motivation: structuring decision-making when designing language features.
  3. Tool demo
    • a realistic example: specifying the design space of the TC39 Records & Tuples (withdrawn) proposal
    • a fictional example: a CSS feature
  4. Automatically finding optimal design.
  5. Open discussion.
