Technical Plenary Day Agenda

Wednesday, 3 March 2004

The Wednesday of the Technical Plenary Week offers a unique opportunity for Working, Interest and Coordination Group members who have registered to gather in one room and discuss technical topics of broad interest to the attendees, and of significant importance to past, present and future of the World Wide Web Consortium. Discussion during this Technical Plenary day will not be considered Member confidential. Slides will be publicly accessible.

If you have IRC, you are welcome to join channel #tp on irc.w3.org:6665 to help record the meeting.


09:00 Session 1: Welcome

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 and outside of that spectrum. The Technical Plenary week is a unique occasion when the people responsible for the work and coordination facilitate their objectives face-to-face. This session provides a brief overview of the W3C's spectrum of near-past, present and near-future work, with the hope that you will better understand (and be inspired by) the spectrum and significance of: (a) our recent accomplishments , (b) our future work, (c) cross-group cooperation and review, and (d) subsequent sessions of the Tech Plenary..

Meeting Chair: Steve Bratt, Chief Operating Officer, W3C [slides ]

09:30 Session 2: Architecture of the World Wide Web and Hot TAG Topics

Description: The TAG is entering its third year of existence. Late last year it issued a Last Call on "Architecture of the World Wide Web, First Edition" which documents principles, constraints, design choices and plain good practice of Web architecture. The intended audience for the architecture document is: participants in W3C activities, implementers of W3C specifications, Web content authors and publishers and other groups developing and integrating Web technologies. The initial presentation will briefly introduce the TAG, its mission and a tour of the architecture document. We will then highlight some of the most hotly contested technical issues currently facing the TAG. Audience participation in both discussions will be encouraged.

Moderator: Stuart Williams (HP) Co-Chair of the TAG

TAG Participants: Dan Connolly (W3C Team), Paul Cotton (Microsoft), Roy Fielding (Day Software), Mario Jeckle (DaimlerChrysler) Chris Lilley (W3C Team), David Orchard (BEA), Norm Walsh (Sun Microsystems), Stuart Williams (HP), Ian Jacobs (W3C Team)

Introduction from Stuart Williams

Hot Topics and Presenters: Versioning and Extensibility (David Orchard), Web Identifiers (Roy Fielding).

10:30 Break
11:00 Session 3: Lightning Tech Talks

Description: Presenters will provide strictly-monitored 3-minute talks on topics that range from interesting, informative, controversial or all of the above. You will have the opportunity to question and comment each presenter.

Moderator: Janet Daly, Head of Communications, W3C.

Topics and Presenters:

  • Jonathan Robie - Making Use Cases and "Incubation" a WG requirement
  • Noah Mendelsohn - Implications of XML 1.1
  • Daniel Dardailler - No Semantic Web without Trust; and vice-versa

  • Mark Birbeck: XForms in Action

12:00 Lunch

Assigned lunch tables?

13:30 Session 4: Adventures with Mixed Markup Language Documents

Description: The growing capabilities of the Web bring with them a growing complexity. In this session, panelists and the audience will examine issues related to mixed language documents, including: (1) what are best practices for defining schemas of mixed language document types; what are limitations of different schema definition languages (e.g., DTD vs XSD vs RELAX NG, etc.)?; (2) how to incorporate language elements from other namespaces: import retaining namespace, or include in host language without retaining namespace; (3) how to integrate languages that have similar but not identical vocabulary, e.g., the hyperlink "a" element in XHTML, SVG, and SMIL all use the same name but different semantics; (4) how to label/identify documents in mixed languages, e.g., what MIME Media Type to use, whether to indicate profile (e.g., using "profile" attribute from HTML/XHTML); (5) how to deal with technologies and mechanisms that are not (yet) namespace aware, e.g., CSS Selectors, [please identify more here], etc.

Moderator: Debbie Dahl, Chair MMI WG; Organizer: Glenn Adams (XFSI) Timed Text WG

Panelists: Mark Birbeck, Masayasu Ishikawa (W3C Team), Rhys Lewis (Volantis) DI WG, Henry Thompson (W3C Team), plus additional TAG and SemWeb reps.

14:30 Session 5: Making Test Suites Work for Working Groups

Description: While more and more WGs need to build test suites to pass their Candidate Recommendation phases and demonstrate interoperability, the testing effort is still seen by some as difficult or cumbersome. In this session, we will share experiences on how to develop a test suite, the tools and methods that make developing test materials easier, and try to show the benefits of testing for the WG, W3C and the Web.

Moderator: Dominique Hazael-Massieux (W3C Team) [slides]

Panelists: Ian Hickson (Opera) [content] and Tantek Celik (Microsoft) [links] CSS WG, Henry Thompson (W3C Team) XML Schema WG, Jeremy Carroll (HP) OWL WG [slides], Patrick Curran (Sun Microsystems) QA WG [slides], Mary Brady (NIST) XML Core WG

15:30 Break
16:00 Session 6: Can I Really Get Good Web Access Without Carrying a PC and a Big Screen?

Description: There are now lots of ways to gain physical access to the web. From PC's to cell phones and digital TV systems to domestic appliances, a host of kinds of device now have web connectivity. As the range increases and the capabilities diverge, is the Web in danger of becoming fragmented? Will there always be a limit to the amount of the Web that can be accessed on particular types of device? This session will examine -- through presentations, demonstrations and discussion -- the tension between the desire for universal access to a single web and the desire to exploit the particular strengths inherent in certain classes of devices.

Moderator: Scott McGlashan (HP) VB WG

Presentations: Rhys Lewis (Volantis) DI WG and Paul Burke (HP) MMI WG.

Demonstrations: Dan Zucker (Access) MMI WG, Michael Johnston (AT&T) MMI WG, Ewald Anderl (Kirusa) MMI WG

Panelists: Rhys Lewis (Volantis) DI WG, Guido Grassel (Nokia) DI WG, Michael Johnston (AT&T) MMI WG, T.V. Raman (IBM) MMI WG

17:00 Session 7: Querying the Web

Description: More and more, the Web is becoming used as an active repository of data in addition to being solely a human-readable browse and explore environment. New technologies are beginning to focus on systems that wish to issue queries and exchange data between heterogeneous data sources on a Web scale. In this session, we look at some of the issues and emerging technologies focused on data access, mining and interchange on the World Wide Web. Specific topics to be discussed include - XQuery: goals and design; RDF DAWG WG: the goals of the newly created* Data Access Working Group; Search - issues in the use of search engine technology in data rich environments.

Moderator: C.M. Sperberg-McQueen (W3C Team)

Participants: Paul Cotton (Microsoft) XQuery WG [slides], Dan Connolly (W3C Team, RDF Data Access WG) [slides], Andy Seaborne (HP), Jonathan Robie [slides]

18:00 Wrap-Up and Adjourn

An evening reception will close the day and start at 8pm in the restaurant of the hotel.
