Moore's Law is well known for telling us that computers double in power at constant price every 2 years or so. But looking at it another way, in two years you could have the same power computer for half the price. Since the start of electronic computing we have seen computers getting unremittingly cheaper, from millions of euros for mainframes, to hundreds of thousands for minis, to ten thousand for a workstation, to one thousand for a PC, to the present day soon-to-be-realised 100 euro netbook, each with a different work mode. Are we done? Or is the ten euro computer the next step? And if it is, what will it look like, and how will we use it?

Thanks to Moore’s law the incremental cost of adding networking to devices is falling rapidly. This creates opportunities for many new kinds of applications. This presentation looks at the potential of Web technologies for reducing the complexity for developing such applications, allowing millions of developers to extend the Web out of the browser and into the real world. This is achieved through mechanisms to provide web run times with access to rich models of users, devices, services, and the environment in which they reside. Privacy and trust are key considerations.

A brief overview on main issues about WCAG 2.0 and how to enforce them in the national legislation.

The talk will recall some of the efforts in the past towards semantic interoperability among libraries. Afterwards, the basic principles of Semantic Web will be presented, showing the role of RDF, RDFS and OWL.

XQuery has been designed by the World Wide Web Consortium as a general purpose XML information processing language, useful in a variety of architectures and environments. For example, XQuery can be used to process XML data on the edge of existing software architectures, where the information is temporary, and is being searched, transformed, or modified, just before being passed along for further processing to other programming languages (e.g. SQL, JAVA, Phyton, Ruby, Javascript). Another increasingly popular usage of XQuery is in XML databases or XML end-to-end architectures. In such architectures, XML is the primary form in which the information is stored and being processed, the information is persistent across successive invocations of programs, and XQuery is the primary language for accessing the information for search, filter, transform, update, and for writing more complex application workflows. Unfortunately, XQuery as it is currently standardized by the W3C is incomplete and cannot be used as such (without proprietary language extensions, or rich APis from other programming languages) in the second type of architectures: persistent databases, or XML end-to-end architectures. Unlike its cousin query language, SQL, XQuery lacks the capability to model, describe and reason about the persistent state of the "database". XQuery 1.0 does indeed have the capability to access at runtime collections of nodes, which could be envisioned as modeling the persistent state of the XML database, yet the language is underspecified in this area. Such collections have no detailed semantics (about copy, order, or multiplicity for example), the language lacks the ability to declare statically such collections, it lacks the static and/or dynamic information that is required for proper compilation and/or execution (e.g. type, update patterns), and it lacks operations to create and modify such collections. Moreover, the language lacks the ability to declare and manage access structures (e.g indexes), and integrity constraints. All such concepts are required for a complete XML/XQuery database story. Unless such concepts are included in the standard language itself, each XQuery implementation will have proprietary extensions to overcome such limitations, or such functionalities will be supplied through non XQuery rich APIs. In both cases, the portability of XQuery applications will be limited, or the simplicity and elegance of XML end-to-end architectures will be hurt. This talk proposes an extension of XQuery called XQuery Data Definition Facility (or XQDDF) to deal with such persistent artifacts: collections, indexes, and integrity constraints. The talk defines the lifetime and evolution of such artifacts: how are they declared, how do they come into existence, how are they used in the compilation and execution of XQuery programs, and how are they shared by multiple XQuery programs.

This paper describes the development of a specialized RELAX NG schema for XHTML and a related XSLT processing chain. This development is the XML-related outcome of a markup project. The non-XML-related outcome are two documents about Japanese layout, one in English, one in Japanese. The paper focuses on the interplay between markup constraints and social constraints, and demonstrates the virtue of hiding XML, for fostering its adoption in new communities.

XML Prague is a conference on XML for developers, markup geeks, information managers, and students

This demo shows how two key technologies can be combined in order to provide a novel breed of scalable information processing systems and architectures: (a) XQuery and (b) Cloud Computing.

Although mobile device capabilities are increasing rapidly, many applications require the powerful capabilities of servers. For example, large vocabulary speech recognition natural language processing, and handwriting recognition require significant processing resources. Furthermore, updating grammars, language models, and vocabularies is much easier to do on a server than on millions of devices. For these reasons, many multimodal applications make use of distributed architectures with different modalities being processed in the cloud. In fact, it appears that a paradigm is emerging in which the device is used primarily for capture of media like audio, images, and ink, but the cloud is used for computationally intensive operations like speech recognition, natural language processing, handwriting recognition and other more advanced capabilities such as translation and biometric processing.The Multimodal Interaction Working Group of the World Wide Web Consortium is developi ng a Multimodal Architecture for supporting distributed, interoperable multimodal applications. The architecture is based on a set of Multimodal Life Cycle Events for communication between components over the Web, and the EMMA (Extensible MultiModal Annotation) for representing user input. This presentation will describe the architecture and discuss how it is particularly suited for developing distributed applications with examples of specific applications.

For managers and practitioners whose organizations already do some accessibility but could benefit from increasing their commitment to accessibility, and organizations that don’t address accessibility at all. At the end of the session, participants will have a complete first draft of their own customized web accessibility business case. (Laptops encouraged.)

We've known how to integrate accessibility in UCD for over 10 years, but many organizations are now using different methodologies such as agile development. Panelists will discuss: new approaches to accessibility; the role of usability specialists versus accessibility specialists; and combining standards with usability techniques to create accessible user experiences.
