W2. The Web and Mobility

This workshop will concentrate on the design of the information set which will be presented to the user on the mobile device. The restrictions of the mobile device are very different from what web users and authors are used to. However, new services, for instance those based on position-dependent information, also become possible. We need to investigate the new rules that the restrictions and possibilities of the mobile environment imposes on us.

This means that experiences from both the existing WAP and pre-WAP services, as well as experimental systems implementing mobile web and information access, are of interest. Issues of information scalability, i.e. formatting aspects such as style sheets, cross-presentation such as aural and visual, and content management such as reformulation, personalization, and conditional access, are of interest.

Subject to the position papers received, the following topics will be covered:

  • information design for mobile web services
  • future technologies and technology directions
  • context negotiated services
  • position relevant/location-dependent information services based on the Web
  • results from research projects implementing services
  • service implementations and experiences from service trials and real services
  • design for universal access

W3. Web Engineering

Web Engineering is an emerging new discipline focusing on successful development of large, complex Web-based systems and applications. It is concerned with the establishment and use of sound scientific, engineering and management principles and disciplined and systematic approaches to Web-based systems development.

This is the third workshop in a successful series on Web Engineering at the World Wide Web conferences. Unlike other workshops that concentrate on one or more specific Web technologies, languages or standards, it focuses on development processes and methodologies, system design, lifecycle and management of large Web-based systems.

The Workshop brings together a mix of Web-developers, development managers, academics and researchers to assess the problems of large Web-based system development, identify key Web Engineering activities and propose approaches and methods for systematic development of Web-based applications. It also provides a forum to review current work in this area, discuss case studies and best practices, and prepare an agenda for further work.

W4. Multimedia on the Web

Text documents containing images have long been commonplace on the Web infrastructure. Multimedia documents, on the other hand, are intrinsically more complex and are only beginning to make an entrance into the Web world - SMIL 1.0 was released as a recommendation in June 1998 and SMIL Boston, the public draft for the next release of SMIL, is currently being worked on.

Web-based multimedia, however, covers broader issues than a single document language. The goals of this workshop are to explore the open issues for web-based multimedia, to gain insights into the potential directions web-based multimedia could go and to obtain a feel for the most fruitful directions.

Among topics to be considered are:

  • (temporal) modeling issues for web-based multimedia;
  • adding temporal relations to existing formats (e.g. (X)HTML, SVG, XML);
  • generation of multimedia;
  • dynamic multimedia;
  • problems of streaming media over the Web;
  • (spatial) Layout issues for multimedia;
  • multimedia style sheets.

W5. Universal Accessibility to the Web

This workshop will discuss approaches to web design to ensure universal accessibility: access to all users (regardless of their particular input/output requirements which may relate to their disability or situation), in all situations (at the office, on the road), from all devices (large screen, small screen, no screen at all). We expect the topics to be explored to include:

  • browser design for non-visual or small screen access
  • use of synthetic speech and non-speech sound output for non-visual interaction
  • developments in HTML, CSS, XML, PDF and Java which assist in designing for universal access
  • tools to support design for non-visual access: the WAI Web Content Accessibility Guidelines, the Bobby validator, the TOM text-only maker etc
  • evaluations of the Guidelines, accessible web pages, tools for universal access
  • understanding the information structure of web sites, semiotic and other approaches
  • use of intelligent proxies for document transformation

We hope to create a synergy between people with an interest in access to the web for users with disabilities and people with an interest in access to the web via new devices such as mobile phones, organizers and in-car systems.

W6. Making Best Use of XML Within the Enterprise

It is now generally accepted that XML will become established as a key enabler for Internet-based enterprise information exchange and distributed computing. However it is often difficult for organisations to know how best to introduce XML, given that it can play a role in so many aspects of an enterprise's information and IT architecture, including:

  • information delivery - enabling information to be assembled from multiple sources to meet individual requirements
  • inter-application messaging - enabling data transfer within and between organizations to facilitate EDI and system interoperability
  • intra-application messaging - to supplement or replace such protocols as CORBA, COM/DCOM and Enterprise Java Beans in the development of distributed computing applications.

This Workshop will bring together leading figures from the XML world representing user organisations, software vendors, consultancies and standards bodies. This group will seek to identify the technical and cultural issues involved in introducing XML to the enterprise and the options that are open to organisations in addressing these issues.

The proceedings of the day will be used as input towards the development of a set of materials which will aim to support organisations setting out to establish clear strategies for the adoption of XML. These materials will be made publicly available and presented for discussion and further refinement at the XML Europe 2000 conference.

During the day there will be a mixture of keynote presentations, discussion within the whole group and work within smaller topic groups.

W7. Web Measurement, Metrics and Mathematical Models

It is vital for current effective use and future growth that we understand what the Web is, how it is growing, who uses it and how it is changing. Despite recent efforts, measuring, characterizing, and modeling the Web remains a difficult task. Much of this trouble results from the distributed nature of information on the Web, while other sources include the dynamic nature of Web information, the sheer size of the Web, the ever increasing international user base, and the difficulty in being able to claim representativeness.

This workshop is intended to bring together the diverse set of researchers, stake holders, and interested parties in Web measurement, metrics, and models. The first half of the workshop will focus on the state-of-the-art in each of these areas. This will be followed by a discussion of the current set of limitations and necessary elements to make rapid progress.

Topics of interest include but are not limited to:

  • graphical and mathematical models of the web
  • appropriate web metrics
  • measurement methods for metrics 
  • statistical sampling of web characteristics
  • static versus temporal data
  • tools for web analysis
  • availability and archiving of web data

The workshop will consist of invited talks and solicited refereed presentations plus a panel to discuss past and future directions. 

Invited Speakers:

  • A. Barabasi, U. of Notre Dame, "19 Degrees of Separation: the Topological Stucture of the WWW"
  • A. Broder, AltaVista, "Web Measurements via Random Queries"
  • B. Huberman, Xerox Parc, "Rules of the Web"
  • J. Kleinberg, Cornell U., "Modeling the Web: Random Graphs, Navigation Strategies, and the Small-World Phenomenon"
  • E. O'Neill, OCLC, "Characteristics of the Web"
