High Level Interoperability Testing for the Web of Things

  • Proposer: Dave Raggett (talk) 13:05, 4 September 2018 (UTC)
  • Summary: W3C has been very successful in defining standards for browsers as the vendor neutral application platform for the Web. The Web of Things seeks to emulate this for an open standards based vendor neutral application platform (aka Web Hub), for open markets of services for things as software objects that expose sensors, actuators or related information services. This session will look at what is needed to test interoperability of Web Hubs with a demonstration of work done by the F-Interop project.
    • Device vendors provide add-on applications that expose devices as things for use by client applications in Web browsers or other Web Hubs. Client applications offer value through remote access to services, and through combining multiple information services, including models of the context. Hubs range in scale from home gateways to large cloud platforms capable of handling the demands of big data. Applications that expose things hide the details of the myriad IoT technologies and standards used to connect to sensors and actuators. Mozilla calls this class of applications “add-ons” for their Things Gateway. A similar open source project is Siemens ThingWeb. This session will also introduce a NodeJS module (Arena Web Hub) aimed at the Node community of developers.

  • Type of session: presentation, discussion
  • Goals: raise awareness of MDN/W3C collaboration impact, seek input on future opportunities

Not Displaying Things: Searchable Invisible DOM + Display Locking

  • Proposer: Chris Harrelson, Domenic Denicola, Rakina Amni
  • Summary: The Chrome team has been working on two related problem areas where developers want to avoid or defer rendering work. One is motivated by use cases of virtualized content (i.e., not putting things outside the viewport into the DOM): it is popular, but does not work with stuff like find-in-page, accessibility, etc. See searchable invisible DOM explainer. Another is display locking, a way for developers to schedule and control DOM updates and rendering work to avoid jank and increase responsiveness. We'd like to explore the problem space in more depth, and seek feedback on our work so far.
  • Type of session: Short presentation followed by discussion
  • Goals: Gather feedback and interest in the use cases and proposed approaches.

Exposing new features as modules instead of globals

  • Proposer: Domenic Denicola (talk) 21:02, 28 September 2018 (UTC)
  • Summary: For a long time, the web has exposed new features on the global object. Now that JavaScript has a module system, can we consider exposing new features as built-in modules instead? Let's discuss the motivation and mechanics of how we would do this. If time permits, let's discuss the package name maps proposal, which is an important piece of making built-in modules polyfillable, virtualizable, etc.

  • Summary: W3C organized a workshop on games back in 2011. Games on the Web were then mostly restricted to casual/puzzle games. The Web was simply not performant enough a platform for high-end games. Today, all technologies are falling into place to make the Web a great platform for gaming, including WebAssembly, WebXR, WebGPU, WebRTC, Service Workers, Gamepad and Pointer Lock. Some of these technologies explicitly started with a view to enabling high-end games on the Web. The Games on the Web roadmap lists these technologies and others, along with their standardisation status. Are there unaddressed requirements? Other technical gaps?
  • Type of session: Short presentation to set the context and raise initial questions, followed by discussion
  • Goals:
  1. Assess whether gaming is a good topic to focus on at W3C. If so, determine scope and next steps. Workshop on games? Create a dedicated steering group (or revive the Games Community Group)? Something else? If not, would another perspective be useful to track these technologies? For instance, CAD, that has similar "needs" but very different goals?
  2. Learn about remaining technical challenges for games on the Web. Packaging? Monetization? Accessibility? Multithreading? Debugging?

  • Type of session: Short presentation followed by discussion.
  • Goals:
  1. Identify video metadata requirements for these markets, and quantify their significance.
  2. Examine the current status of WebVTT metadata cue support in web browsers.

Personalization - How Should It Be Implemented?

  • Proposer: Charles LaPierre (talk) 14:10, 12 October 2018 (UTC)
  • Summary: The Personalization TF now part of the APA would like your help in deciding which implementation schema we should use for our Personalization modules we have been developing.

This work came out of the Cognitive Accessibility Task Force (COGA), the former Indie-UI WG, and other WAI groups and has been worked on previously under ARIA. The goal of the Personalization task force is to enable the adaptation of web content to user needs far beyond what is currently supported, so that more usergroups can be included in the digital world and content can adapt to more scenarios such as stress and illness. Sometimes users may need simplification of text and concepts or translation into symbols. Others may need content that is free of numbers, minimizes distractions, or provides additional help. The author augments the content to identify options, simplications, or replacements. User agents or other technologies use these semantics to augment or adapt the content based on identified user preferences.


  • The content might specify that, "9 out of 10 people prefer coffee over tea". The author would identify the "9 out of 10” phrase and provide "almost all" as the number free alternative. Most symbol sets are proprietary.
  • People who use symbols to communicate often don’t understand symbols from another set. There is a need for a standard vocabulary that content authors can use to identify items, and an open source symbol set is being developed through UNICEF. These standard tokens can then be mapped to each unique symbol set.

The task force has 3 modules and an explainer document in editor draft status. Below are links to these documents and to a Google Document comparing the implementation strategies we have explored. The task force needs your help to select the best implementation schema for the personalization semantics. We have eliminated RDFa, HTML Microdata, and ARIA attributes as not practical at this time.
