Participants will learn the latest features of Cascading Style Sheets (CSS), such as media queries, columns, image borders, semi-transparent colors, advanced selectors and many more.

As the Web gained adoption as a technology platform over the past 20 years it transformed every industry. We are seeing the next round of those transformations occurring based on the Open Web Platform which is the current set of Web Standards defined by the World Wide Web Consortium (W3C). We will discuss how this platform is impacting all industries including Mobile, Web & TV and Digital Publishing. Although the boundaries of the platform continue to evolve, industry leaders speak nearly in unison about how HTML5 is the cornerstone for this platform. But the full strength of the platform relies on many more technologies that W3C and its partners are creating, including CSS, SVG, WOFF, the Semantic Web stack, XML, and a variety of APIs.

The majority of corporate websites are still not designed to work well on mobile devices. Some companies provide native apps, but these are expensive to develop. The problem is getting worse with new platforms such as tablets, TVs and cars. This talk presents work on an open source browser-based collaborative design assistant that simplifies the development of responsive web applications that work effectively on different platforms. This is based upon an expert system that dynamically updates the user interface design to reflect the developer’s decisions and ensure consistency across platforms. This is implemented in terms of constraint propagation and search through the design space. An additional benefit is the ease of providing accessible user interfaces in conjunction with assistive technologies.

A look at how the public sector information space might look in 2020, taking into account current thinking in the European Commission's ISA Programme

What are the technical problems with using open data? Are there current technologies that could and should be standardized? What technical approaches are emerging as best practices? Can Linked Data play nicely with other formats? These are the broad questions that were addressed in a workshop jointly organized by the World Wide Web Consortium (W3C), the Open Data Institute and the Open Knowledge Foundation, hosted by Google right in the heart of London’s Tech City of Shoreditch in April. Phil Archer will present a summary of the topics discussed and how it is likely to affect future standards work at W3C.

An in-depth look at the Selectors module for CSS.

Enthusiasm and political support for open data is based on three pillars: that it will increase transparency, improve efficiency and stimulate innovation. Meeting these promises has had several spectacular successes but there remains a lot of work to do before data becomes as much a part of the public infrastructure as, say, transport or leisure facilities. W3C's 'go to person' for open data and eGov in Europe assesses the road ahead, looking for pitfalls suggesting routes around some of the obstacles.

SEMIC 2013 will offer a unique opportunity to explore and discuss how Public Administrations are tackling Semantic Interoperability issues to make information exchange more efficient and effective.

Phil Archer reviews the progress of the ISA Programme's Core Vocabularies within W3C's Government Linked Data Working Group and looks ahead to future vocabulary support at W3C.

The web is now over 20 years old, but still in its infancy. Books printed 100 years ago are still readable, and available in many cases. Will we still be able to read and access websites made today in 100 years time? Or will all our content be lost to future ages? What is needed to make the web age-tolerant? What do we want from the web in both the short and long term? Content Despite the use of style-sheets, the current web is almost completely visually-oriented. This locks the content into one particular representation, and makes it hard to repurpose. What we need is a web that is primarily content-oriented, with a final phase of presentation; only in that way can content be repurposed in the same way that data can be. Design for the web should be like design for a house style. It has a general style that the content can flow into. Multi-device We don't want to have to produce copies of our websites for each new type of platform or device. There needs to be a generic method of repurposing content to the formfactor of the device accessing it. Accessibility Even when we are 80, we will still want and need to use the web. How can we make our 30-year-old selves sensitive to the problem of our less-abled Authorability With the coming of HTML5, the web has stopped being about documents, and started being about programs. Now only programmers can produce modern web pages. What can be done to alleviate the problem? Availability HTTP, the protocol used for serving Web pages, has served us well for the last 20 years, but is beginning to show its age: it has become a single-point-of-failure for content. It enables DDoS attacks, makes it easy for governments and other agencies to censor sites and content, and just when a website becomes super-popular it can fail causing the website to crash and be unreachable. This talk will cover these points, and general approaches that could be used to make a coherent future web.

XForms is a high-level tool for defining user interfaces to XML data. With a design based on years of experience with the simple forms of HTML, XForms systematically distinguishes between the model (the information structures being edited, in the form of sets of XML documents) and the user interface and its appearance. As an XML vocabulary, XForms is embeddable in arbitrary host document languages; its user interface widgets can easily be represented in different ways for different devices and users. Forms of arbitrarily complex fixed structure can be easily represented in XForms. Mixed content, variable-depth recursion, and structural modifications to the model are more challenging. This introduction to XForms provides an overview of its capabilities and current limits and the prospects for overcoming them.

What if you could see everything as XML? XML has many strengths for data exchange, strengths both inherent in the nature of XML markup and strengths that derive from the ubiquity of tools that can process XML. For authoring, however, other forms are preferred: no one writes CSS or Javascript in XML. It does not follow, however, that there is no value in representing such information in XML. Invisible XML is a method for treating non-XML documents as if they were XML, enabling authors to write in a format they prefer while providing XML for processes that are more effective with XML content. There is really no reason why XML cannot be more ubiquitous than it is.

Le Livre Électronique est probablement le plus gros consommateur de Standards du Web actuel hors du Web lui-même. Les points de convergence entre notre moyen d'expression préféré et les eBooks sont nombreux mais les points de divergence également. Quels sont les apports du Livre Électronique dans HTML, les CSS, les autres langages ? Quels sont les spécifications du W3C qui doivent impérativement progresser pour aider le Livre Électronique ? Pouvez-vous transformer une collection de documents Web en Livre Électronique en moins que temps que Tristan Nitot en a besoin pour passer son fameux tutu rose ? Comment le W3C et l'IDPF, le consortium chargé d'EPUB, travaillent-ils ensemble ? Le Livre Électronique et le Web évoluent-ils à la même vitesse ? Bref, tout ce que vous avez voulu savoir sur les dessous Web du Livre Électronique sans jamais oser le demander.
