Next Generation Web Technologies Build on Stable Foundation


Read below what W3C Members have to say about HTML5


28 October 2014 — The World Wide Web Consortium (W3C) published a Recommendation of HTML5, the fifth major revision of the format used to build Web pages and applications, and the cornerstone of the Open Web Platform. For application developers and industry, HTML5 represents a set of features that people will be able to rely on for years to come. HTML5 is now supported on a wide variety of devices, lowering the cost of creating rich applications to reach users everywhere.




"Today we think nothing of watching video and audio natively in the browser, and nothing of running a browser on a phone," said Tim Berners-Lee, W3C Director. "We expect to be able to share photos, shop, read the news, and look up information anywhere, on any device. Though they remain invisible to most users, HTML5 and the Open Web Platform are driving these growing user expectations."

HTML5 brings to the Web video and audio tracks without needing plugins; programmatic access to a resolution-dependent bitmap canvas, which is useful for rendering graphs, game graphics, or other visual images on the fly; native support for scalable vector graphics (SVG) and math (MathML); annotations important for East Asian typography (Ruby); features to enable accessibility of rich applications; and much more.

HTML5 is Widely Deployed

HTML5 has been in use for years. According to a 2014 Vision Mobile Survey, 42% of 10,000 developers surveyed are using the combination of HTML, CSS, and JavaScript for all or part of their mobile applications. Gartner identified HTML5 as one of their top 10 mobile technologies and capabilities for 2015 and 2016, saying HTML5 "will be an essential technology for organizations delivering applications across multiple platforms."

To help achieve the "write once, deploy anywhere" promise of HTML5 and the Open Web platform, during the 22 months since W3C announced the completed definition of HTML5, the W3C community has been adding to the HTML5 test suite, which includes over 100,000 tests and continues to grow. The Test the Web Forward community effort now plays an important and ongoing part in driving Open Web Platform interoperability.

With today's publication of the Recommendation, software implementers benefit from Royalty-Free licensing commitments from over sixty companies under W3C's Patent Policy. Enabling implementers to use Web technology without payment of royalties is critical to making the Web a platform for innovation.

What's Next: Application Foundations for Developers, New Use Cases for the Web

Though HTML5 is widely deployed and popular among developers, we have more to do to achieve one of the promises of the Open Web Platform: lowering the cost of developing powerful, cross-platform applications. In an October blog post, W3C CEO Jeff Jaffe states that "now that HTML5 is done, W3C should do more to strengthen the parts of the Open Web Platform that developers most urgently need for success." To help communicate and drive agreement on those priorities, Jaffe enumerates "Application Foundations" that must be strengthened to achieve the next generation platform:

  • Security and Privacy: identity, crypto, multi-factor authentication, privacy protection
  • Core Web Design and Development: HTML next generation, style, layout, graphics, animations, typography
  • Device Interaction: access to hardware and sensors such as bluetooth, NFC, vibration, etc.
  • Application Lifecycle: background tasks to manage offline, push, geofencing, sync
  • Media and Real-Time Communications: WebRTC, streaming media
  • Performance and Tuning: profiling, enhancements such hints and pre-loading, responsive design
  • Usability and Accessibility: ensuring the Web is accessible to all and supports the world's languages
  • Services: social Web, payments, annotations, Web of data

W3C will discuss this new framework and its impact on W3C's agenda at its annual Membership meeting (TPAC) this week.

Stronger foundations will also make it easier to incorporate new features for the Web, which are proposed every day, inside and outside W3C. W3C is growing to accommodate the use cases of the payments, automotive, digital publishing, telecommunications, and entertainment industries. At the same time, 4500 engineers are socializing new ideas for the Web in more than 180 Community and Business Groups.


W3C first wishes to thank Ian Hickson (Google), the principal architect of the HTML5 specification, who has made seminal contributions to the HTML language.

W3C thanks HTML Working Group co-Chairs Paul Cotton (Microsoft), Sam Ruby (IBM), and Maciej Stachowiak (Apple) for their leadership in bringing HTML5 to Recommendation, and the entire HTML Working Group for their contributions.

It’s good to see HTML5 reach the Recommendation stage. We were one of the first organizations involved in HTML5 because we believe in continuing to evolve the open Web platform to support innovation and help users. We contributed many widely adopted technologies such as WebGL and helped pioneer technologies like WebRTC. We have also expanded the functionality of the Web on mobile through the use of WebAPIs, bringing Web app developers the power to access phone hardware. Many of these APIs are currently going through the standardization process. We’re now working with the W3C to help lead the work behind the HTML5 test suite, ensuring that tests can be run in an automated way, so that users and developers can benefit from more consistent behavior between browsers.

The Paciello Group

HTML5 is a great leap forward for an accessible web. In HTML5, accessibility is a core design principle. For the first time the semantics of HTML have been mapped, and implementation requirements defined in terms of the way HTML semantics are conveyed to people using assistive technologies. The addition of new interactive controls, native video and captioning, and new structural elements in HTML5, make it easier than ever for developers to create HTML interfaces that are usable by everyone. The inclusion of WAI-ARIA in HTML also provides developers with the tools and information to create accessible custom content and controls that extend the core features of HTML. The Paciello Group (TPG) is both proud and honoured to have contributed to the development of HTML5, but recognises that it is not an end in itself. HTML5 represents a very positive step in the evolution of the language of the web, and TPG welcomes the opportunity to continue contributing to its positive development.

Mike Paciello, Founder The Paciello Group (TPG)
