W3C announces today a Workshop on Web-Based Signage, 14-15 June in Tokyo (Chiba), Japan, and hosted by NTT. W3C is organizing a workshop to share perspectives, business use cases, and technology requirements so that the Open Web Platform can be used on large digital displays (such as those found in city squares and at sporting events). We invite operators of consumer electronics companies, digital signage platforms, advertisers, browser vendors, sign owners, and others to participate in this discussion. W3C membership is not required to participate in this workshop. Please submit a statement of interest by 16 May and learn more about participation.

The Web Applications Working Group has published a Last Call Working Draft of Server-Sent Events. This specification defines an API for opening an HTTP connection for receiving push notifications from a server in the form of DOM events. The API is designed such that it can be extended to work with other push notification schemes such as Push SMS. Comments are welcome through 17 May. Learn more about the Rich Web Client Activity.
