HTML5 was released in 2014 as the result of a concerted effort by the W3C HTML Working Group. The intention was then to begin publishing regular incremental updates to the HTML standard, but a few things meant that didn’t happen as planned. Now the Web Platform Working Group (WP WG) is working towards an HTML5.1release within the next six months, and a general workflow that means we can release a stable version of HTML as a W3C Recommendation about once per year.
The core goals for future HTML specifications are to match reality better, to make the specification as clear as possible to readers, and of course to make it possible for all stakeholders to propose improvements, and understand what makes changes to HTML successful.
The plan is to ship an HTML5.1 Recommendation in September 2016. This means we will need to have a Candidate Recommendation by the middle of June, following a Call For Consensus based on the most recent Working Draft.
To make it easier for people to review changes, an updated Working Draft will be published approximately once a month. For convenience, changesare noted within the specification itself.
Longer term we would like to “rinse and repeat”, making regular incremental updates to HTML a reality that is relatively straightforward to implement. In the meantime you can track progress using Github pulse, or by following @HTML_commitsor @HTMLWGon Twitter.
Working on the spec…
The specification is on Github, so anyone who can make a Pull Request can propose changes. For simple changes such as grammar fixes, this is a very easy process to learn – and simple changes will generally be accepted by the editors with no fuss.
If you find something in the specification that generally doesn’t work in shipping browsers, please file an issue , or better still file a Pull Requestto fix it. We will generally remove things that don’t have adequate support in at least two shipping browser engines, even if they are useful to have and we hope they will achieve sufficient support in the future: in some cases, you can or we may propose the dropped feature as a future extension – see below regarding “incubation”.
HTML is a very large specification. It is developed from a set
of source files, which are processed with the
Bikeshed preprocessor. This automates things like links between
the various sections, such as to element definitions. Significant
changes, even editorial ones, are likely to require a basic
knowledge of how Bikeshed works, and we will continue to improve
the documentation especially for beginners.
HTML is covered by the W3C Patent Policy, so many potential patent holders have already ensured that it can be implemented without paying them any license fee. To keep this royalty-free licensing, any “substantive change” – one that actually changes conformance – must be accompanied by the patent commitment that has already been made by all participants in the Web Platform Working Group. If you make a Pull Request, this will automatically be checked, and the editors, chairs, or W3C staff will contact you to arrange the details. Generally this is a fairly simple process.
For substantial new features we prefer a separate module to be developed, “incubated”, to ensure that there is real support from the various kinds of implementers including browsers, authoring tools, producers of real content, and users, and when it is ready for standardisation to be proposed as an extension specification for HTML. The Web Platform Incubator Community Group (WICG)was set up for this purpose, but of course when you develop a proposal, any venue is reasonable. Again, we ask that you track technical contributions to the proposal (WICG will help do this for you), so we know when it arrives that people who had a hand in it have also committed to W3C’s royalty-free patent licensing and developers can happily implement it without a lot of worry about whether they will later be hit with a patent lawsuit.
W3C’s process for developing Recommendations requires a Working Group to convince the W3C Director, Tim Berners-Lee, that the specification
“is sufficiently clear, complete, and relevant to market needs, to ensure that independent interoperable implementations of each feature of the specification will be realized”
This had to be done for HTML 5.0. When a change is proposed to HTML we expect it to have enough tests to demonstrate that it does improve interoperability. Ideally these fit into an automatable testing system like the “ Webapps test harness“. But in practice we plan to accept tests that demonstrate the necessary interoperability, whether they are readily automated or not.
The benefit of this approach is that except where features are removed from browsers, which is comparatively rare, we will have a consistently increasing level of interoperability as we accept changes, meaning that at any time a snapshot of the Editors’ draft should be a stable basis for an improved version of HTML that can be published as an updated version of an HTML Recommendation.
We want HTML to be a specification that authors and implementors can use with ease and confidence. The goal isn’t perfection (which is after all the enemy of good), but rather to make HTML 5.1 better than HTML 5.0 – the best HTML specification until we produce HTML 5.2…
And we want you to feel welcome to participate in improving HTML, for your own purposes and for the good of the Web.
