The W3C has published the July 2014 edition of Standards for Web Applications on Mobile, an overview of the various technologies developed in W3C that increase the capabilities of Web applications, and how they apply more specifically to the mobile context.
A deliverable of the HTML5Apps project, this edition of the document includes changes and additions since April 2014, notably a new section covers the emerging field of integrated payments on the Web, following recent work started by W3C in this space. Learn more about the Web and Mobile Interest Group (WebMob).
If you think you have figured out your strategy for mixing and matching support for web and mobile channels, keep in mind that this is not a a one-time project but an ongoing affair. There is always discussion about this at our conference, but this W3C activity is a good way to keep up with details minus the bias and hype. Of course the W3C promotes their standards, but that is not a bad thing.
