W3C @ WWW2015
20-21 May 2015, Florence, Italy

Smart TVs, set-top boxes, Google Chromecast, Miracast dongles, Apple Airplay... End users own and use multiple devices at once that may all run HTML5 applications or render content streamed from another device. However, there is no easy way for an HTML5 application to take advantage of available secondary screens and companion devices.

This session will demonstrate recent works around network service discovery, APIs to present content on secondary devices, ways to synchronize content across devices, and will discuss challenges and solutions to develop HTML5 applications that may run on multiple screens at once.

Web technologies and standards allow applications to manipulate sound and transform the browser into a digital audio workstation, capable of real-time audio processing. Audio on the Web has been fairly primitive until very recently. The introduction of the audio element in HTML5 is very important, but not powerful enough to handle more complex audio applications in sophisticated Web-based games or interactive applications, for example.  This session will demonstrate audio-related Web technologies. We welcome demos from  researchers, developers, designers and standards gurus, so contact us beforehand!

In contrast to native, HTML5-based apps are platform and device agnostic. However, today, HTML5 lacks important functionalities such as rich APIs to interact with devices. This session is seeking input from participants on ways to achieve greater interoperability on the Web.

The Web is more and more used in mission-critical applications and services. The initial "same origin" rule has shown its limitations as the unique rule for Web application development. The Web security architecture panel will explore all corners of Web security, from the protocol layer to the application layer. During this session, the audience is invited to interact with fine experts in Web security.

The growing digitization and networking process within our society has a large influence on all aspects of everyday life. Large amounts of data are being produced permanently, and when analyzed and interlinked, they have the potential to create new knowledge and intelligent solutions for economy and society. This session will present BigDataEurope, a platform that aims to lower the barrier to innovative products and services based on diverse and large-scale data assets.
