The future of the web is fast approaching. HTML5, the successor to today’s HTML 4, the lingua franca of the web, has reached the Last Call stage and is beginning to look like a finished spec. While it will be some time before HTML5 can be called complete, forward-thinking browsers already support much of the spec.

HTML5 represents the biggest leap forward in web standards in almost a decade, but what comes after HTML5? HTML6?

As it happens, no. The WHAT Working Group, which, along with the World Wide Web Consortium (W3C), is helping to create HTML5 and beyond, has already decided to move to a non-versioned development model after the release of HTML5. That means, in the future, there will simply be HTML.

What will this HTML look like you ask? Well, Mark Pilgrim, who works on the WHAT Working Group, has started a new series of posts on the group’s blog entitled What’s Next in HTML?

The answer, at least for now, is a possible new tag: .

As you would expect will offer web developers a way to access devices, for example your PC’s webcam or perhaps your mobile device’s accelerometer.

The obvious application for the device tag is video chat — something currently only possible using proprietary tools like Adobe Flash. As Pilgrim points out in his post, if you combine the existing video tag and web socket tools of HTML5 with the new device tag, all the elements necessary for an online video chat application are in place.

Before web developers get too excited it’s important to realize that is a long, long way from being a real HTML element. As Pilgrim notes: “the entire device API is still in its infancy… nobody has even started implementing a prototype of that piece yet, and the whole idea might be scrapped.”

That shouldn’t be too surprising for those of you following the bleeding edge of the web, after all we’ve already been teased with the promise of a single video codec only to see that vanish.

But with any luck, the device tag won’t suffer a similar fate and one day web developers will be able to take advantage of yet another set of tools that were once the sole province of desktop software.
未来的 Web 正在加速到来，HTML5 已经完成细则的制定并蓄势待发，尽管它的实现仍待时日，一些有前瞻眼光的浏览器已经开始支持 HTML5 的部分功能。HTML5 是10年来 Web 标准的最大改进，然而 HTML5 之后是什么？是 HTML6 吗？

不是。 WHAT 工作组 (WHAT Working Group) 正联合 W3C 制定 HTML5 的后续版本的细则，他们决定在 HTML5 之后，制定无版本号的 HTML，意味着，今后的 HTML 将直称 HTML。这种无版本号的 HTML 是什么样？WHAT 工作组的 Mark Pilgrim 最近在他的系列博客文章中对此做了介绍：

到目前为止，最可能的改变是，新增一个标签，该标签将提供对某些设备的访问，比如，摄像头或你的移动设备的速度传感器。

该标签最显而易见的应用是视频聊天，目前，这种应用只能通过特定的程序，如 Adobe Flash 进行。Pilgrim 在他的博客文章中指出，设备标签结合 HTML 5 的视频标签，足以实现在线视频聊天应用。

不过，先不要高兴太早，这一过程还遥遥无期，整个设备 API 还在孕育中，还没有任何原型实现，而这一想法也有可能半路夭折。作为 Web 开发者，我们对这种事并不陌生，就像那个无疾而终的视频解码器的承诺。

不过，如果设备标签最终得以实现，Web 开发者们将拥有又一种过去只有在桌面程序中才有的工具。
