W3C Communication will provide communication material, available in English and Hungarian. The booth will be run in coordination with the W3C Hungarian Office.
Each Recommendation not only builds on the previous, but is designed so that it may be integrated with future specifications as well. W3C is transforming the architecture of the initial Web (essentially HTML, URIs, and HTTP) into the architecture of tomorrow's Web, built atop the solid foundation provided by XML.
W3C provides demonstrations of some of its technologies and tools:
PhotoRDF is a W3C Note, which describes a project for describing & retrieving (digitized) photos with (RDF) metadata. It describes the RDF schemas, a data-entry program for quickly entering metadata for large numbers of photos, a way to serve the photos and the metadata over HTTP, and some suggestions for search methods to retrieve photos based on their descriptions.
The data-entry program has been implemented in Java, a specific Jigsaw frame has been done to retrieve the RDF from the image through HTTP. The RDF schema uses the Dublin Core schema as well as additional schemas for technical data.
There is sample source code available for download. The system can be useful for collections of holiday snapshots as well as for more ambitious photo collections.
IsaViz is a visual environment for browsing and authoring RDF models represented as node-link diagrams, which make the graph structure easier to understand and navigate compared to textual serializations like RDF/XML. However, such diagrams can quickly become big and over-cluttered. Features such as zoomable user interfaces and overview windows, featured in IsaViz 1, offer enhanced navigation capabilities and are a first (partial) solution to this problem. Another complementary solution consists in further taking advantage of the properties associated with visual representations to offer better and easier-to-understand diagrams.
IsaViz 2 features a mechanism called Graph Stylesheets (GSS) which makes it possible to add style to RDF models represented as standard node-link diagrams. This mechanism allows one to specify alternate layouts, hide information and use more perceptual dimensions to encode information visually, thus reducing the number of entities in the graphical representation while at the same time increasing the amount of parallelism in the user's cognitive processing of the model.
Amaya is a complete Web authoring and browsing tool, which interacts with users through a WYSIWYG interface (see screenshot). Amaya started as an HTML + CSS style sheets editor. Since that time it was extended to support XML and an increasing number of XML applications such as the XHTML family, MathML, and SVG. It allows all those vocabularies to be edited simultaneously in compound documents, through a WYSIWYG style of interface. This interface simplifies the creation of valid documents as users do not need to write the Markup by hand.
Work on Amaya started at W3C in 1996 to showcase Web technologies in a fully-featured Web client. The main motivation for developing Amaya was to provide a framework that can integrate as many W3C technologies as possible. It is used to demonstrate these technologies in action while taking advantage of their combination in a single, consistent environment.
Features of Amaya include the following: both browsing and authoring Web pages, maintaining a consistent internal document model adhering to the DTD, native SVG and MathML support, helping authors create hypertext links with a single click, collaborative annotations. Download Amaya binaries for Solaris, Linux, and Windows. Source code is available.
SVG 1.1 is a W3C recommendation, published 14 January 2003.This specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 1.1, a modularized language for describing two-dimensional vector and mixed vector/raster graphics in XML.
SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text. Graphical objects can be grouped, styled, transformed and composited into previously rendered objects. The feature set includes nested transformations, clipping paths, alpha masks, filter effects and template objects.
SVG drawings can be interactive and dynamic. Animations can be defined and triggered either declaratively (i.e., by embedding SVG animation elements in SVG content) or via scripting.
CSS level 3 is the third level of CSS (Cascading Style Sheets), the language for specifying style and layout for HTML and XML. It extends the already existing levels 1 and 2. CSS3 will provide more control over layout; better support for Japanese, Arabic and other typographic traditions; more control over colors and images, including transparency; and much more.
Some modules of CSS3 are ready to be implemented, others are still under development. The status can be followed on the "Roadmap".
The Synchronized Multimedia Integration Language (SMIL 2.0), currently a W3C Recommendation, enables simple authoring of interactive audiovisual presentations. SMIL is typically used for "rich media"/multimedia presentations which integrate streaming audio and video with images, text or any other media type. SMIL 2.0 specifies different profiles and therefore allows implementations on various platforms such as PC, PDA and mobile phones.
XForms, the Next Generation of Web Forms in contrast, is currently a W3C Candidate Recommendation. Basically, XForms allows to separate the User Interface (a standard set of visual controls), the XML instance data (the collected data), and the XForms Model defining the individual model items and constraints of forms. XForms is already largely implemented in multiple browsers.
The W3C was created to lead the Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability. It is an international industry consortium jointly run by the MIT Laboratory for Computer Science (MIT LCS) in the USA, the European Research Consortium for Informatics and Mathematics(ERCIM) headquartered in France and Keio University in Japan. Services provided by the Consortium include: a repository of information about the World Wide Web for developers and users, and various prototype and sample applications to demonstrate use of new technology. To date, over 400 organizations are Members of the Consortium. For more information see http://www.w3.org/
