Description: Two unique features of the World Wide Web Consortium are its broad spectrum of foundational work, coupled with its strong emphasis on coordination across that spectrum (and even outside of it). The Technical Plenary week is a unique occasion when the people responsible for the work and coordination facilitate their objectives face-to-face. This introductory session motivates subsequent sessions, and aims to educate and inspire through an overview of: (a) the W3C's spectrum of work, (b) your place within it, (c) the value of cross-group review, and (d) the wave of new technology coming up for review.

Meeting Chair: Steve Bratt, Chief Operating Officer, W3C

Description: New ways of accessing the Web will impact traditional Web architecture in many ways. This session explores implications for the Web from three perspectives: (1) new types of devices with capabilities that differ from those of traditional desktop browsers, (2) new modalities such as voice and digital ink, (3) providing access to the Web for users whose disabilities prevent them from making full use of a traditional interface.

Description: Thinking about the places where the Architecture of the Web has fissures and gaps and proposing solutions for closing them, is what the TAG has spent a great deal of time doing in its first year. The session (re-)acquaints you to the TAG, explains how it relates to you in your WG work, and delivers a set of its works in progress, including the "Architecture of the World Wide Web" document and technical issues and findings regarding Namespace documents, an XML profile and XML id semantics.

Panelists: Technical Architecture Group members - Tim Berners-Lee, Dan Connolly, Paul Cotton, Roy Fielding, Ian Jacobs, Chris Lilley, David Orchard, Norm Walsh, Stuart Williams

Presentations:

1. Stuart Williams -- TAG Introduction
2. Dan Connolly -- Architecture Document Overview
3. Chris Lilley -- XMLl ID for Well-Formed Documents
4. Norm Walsh -- XML Profiles

Description: Any W3C Working Group that has published a specification for review knows the labor of providing clarifications on terminology. This session will identify common problems and present early work on a potential solution to ease the process.

Description: As the Web has grown, so has the community of people working on its development. If for no other reason than the sheer volume of work being produced, the community may be dividing into subcommunities focused on different application areas such as hypertext, Web services, the semantic Web, Web infrastructure and the grid. If the Web is to remain cohesive, we must define the principles and architecture we all share and define where and how different groups have freedom to be different. This panel will discuss what the hypertext Web, Web services, the semantic Web and the http Web have in common, where they differ and how they relate to each other.

Panelists:

• Steven Pemberton, Chair, HTML and XForms WGs; on the Hypertext Web
• Roy T. Fielding, TAG, on One Web or Three? HTTP
• Noah Mendelsohn, XML Protocol WG; on Web Services
• Brian McBride, Co-Chair, RDF Core WG; on the Semantic Web

Moderator: Stuart Williams, TAG

• One Web or Four?
