Chrome 15 and above supports mapping input fields to specific types of data to improve the accuracy of autofill tools. The new WHATWG autocompletetype attribute proposal from Ilya Sherman of Google proposes 36 mapped tokens and two sections for autofill agents entering name, address, contact, credit card, business, or birthday data in a web browser.

Open Graph protocol is a set of HTML+RDF markup elements used to summarize webpages on the public Internet when those pages are shared on Facebook, Google+, mixi, LinkedIn, and more. In this post I will summarize Open Graph protocol markup for easy inclusion in your site templates.

Google released Chrome 13 into its stable channel this morning with over 5200 revisions including Instant Pages. If your webpages are not already differentiating between attended and unattended pageviews using the Page Visibility API for site analytics (and other functions assuming live eyeballs and the opportunity for interaction with page elements) your pageview numbers are now likely inflated.

Google search result pages now trigger a prefetch of top search result links in an effort to make navigating search results as easy as changing channels on your television. If Google’s search algorithms determine there is a significant probability of user click-through on particular result they will instruct supporting browsers to preload the entire destination page including images, JavaScript, advertisements, and analytics. Update your web pages to be aware of the current page visibility state and track interactions, not background tasks.

Google will roll out a change to its search results pages later this week designed to better capture outbound clicks. Google search result pages will link to a gateway URL before delivering the visitor to his final destination. These gateway URLs will replace search result URLs exposed via the Referer HTTP header.

On Tuesday Yahoo! launched its Open Strategy, exposing Yahoo! account data and social connections to third-party developers. Yahoo!

In this post I will provide an overview of the new Yahoo! services and its impact on both Yahoo! and third-party developers. Yahoo! Open Strategy is one of the keynote presentations at Widget Summit next week.

Google released its second web browser yesterday afternoon, adding additional headroom for web applications stretching the limits of what it’s possible to accomplish within a web browser. The Google Chrome team assembled domain experts in various fields over the past six years, both through direct hires and acquisitions, to create a new browser and its critical components from scratch. GMail and Google Maps pushed the Web to its limits, taking advantage of browser technologies invented in Redmond but left dormant for far too long. Contributing to Firefox’s core, writing browser extensions, and championing HTML could only take the $150 billion company so far: they needed to own the full browser to push their Web efforts forward at full speed.

Microsoft has extended the OpenSearch protocol with a new search suggestions data formats expressed XML or JSON. The new format will display real-time search results, summaries, images, and even search result classifications inside the browser chrome for any site owner supplying the appropriate format. In this post I’ll teach you how to add search suggestions to your OpenSearch description document for instant search suggestions in IE8.
