</H2>
<P>
<I>by <A HREF="mailto:khare@w3.org">Rohit Khare</A></I>
<P>
W3C's history has long been intertwined with the International World Wide
Web Conference Series -- starting with W3C's birth at the very first Geneva
conference through to its management of WWW4 (Boston) and WWW5 (Paris). In
1997, the WWW6 torch passes to Santa Clara, and W3C will be there in force.
<P>
During the week of April 7-11, W3C's worldwide technical staff will participate
in workshops and tutorials, a W3C Conference Track, Developer's Day sessions,
and in several adjacent W3C Member meetings. This article presents some
background on our mission at W3C; please keep an eye on our
<A HREF="http://www.w3.org/pub/Conferences/WWW6">W3C@WWW6 Overview Page</A>
for the latest information. W3C Members are also strongly encouraged to
participate in the conference, and in our panels, workshops, and symposia,
as described below.
<P>
It is worth noting that WWW6, like its predecessors and next year's WWW7
(Brisbane, Australia), are sponsored by the
<A HREF="http://www.iw3c2.org/">International World Wide Web Conference
Committee</A>, not the Consortium.
<H3>
  W3C Conference Track
</H3>
<P>
W3C will be using its main Conference track as an 'Annual Report' to the
wider Web Community. Much like the semiannual Advisory Committee reports,
this is our opportunity to present and defend our agenda to the community
we serve. The W3C track as a whole is a primer on the entire range of our
activities:
<UL>
  <LI>
    Keynote on W3C History, Structure, and Recent Accomplishments.
  <LI>
    Executive Overviews of each Domain
  <LI>
    Project Updates on each of our several Activity Areas
  <LI>
    Panel discussion with Member representatives in several Activity Areas
  <LI>
    "Town Hall" session with W3C's Management Team
</UL>
<P>
We hope this agenda will help us reach out to a rapidly expanding constituency
who may not be familiar with W3C's origin, scope, or expertise. We will also
back up the conference program with our first W3C Folio, a high-quality overview
brochure.
<H3>
  Developer's Day &amp; History Day
</H3>
<P>
While many academic, user, and engineering communities converge at WWW
conferences, the organizers have traditionally reserved the last day of the
week for the truly hard-core, the hackers, protocol developers, and visionaries
behind tomorrow's Web technology. WWW6 embraces this charge with an expanded
Developer's Day and a brand-new History Day on Friday April 11th.
<P>
The new Developer's Day will reach out to new "developer" communities: content
providers, business developers, authors, etc. W3C's contribution will focus
mainly on the original core, with technical talks from all three Domains.
Architecture Domain will host discussions of HTTP/1.1 implementation,
performance, and its future at the IETF, along with briefings on real-time
and multimedia technology. User Interface Domain is preparing to dissect
Amaya and its underlying Thot library, as well as a host of HTML and CSS
related developments. Technology &amp; Society Domain's various project team
reports will bring together W3C staff and Member organization volunteers
to talk to developers about implementing PICS, Digital Signatures, and more.
<P>
History Day is an effort to capture the lore and traditions of the seven-year
old Web community. W3C Director Tim Berners-Lee will present a joint Keynote
speech, "History and Developers" for both of these programs. In addition,
W3C staff will be assisting History Day organizers in locating speakers,
timelines, and other matters.
<P>
Developer's Day was the subject of
<A HREF="http://www.webtuitive.com/www6/feb97.html">a recent WWW6 Newsletter
feature story</A>, as well.
<H3>
  Resources
</H3>
<P>
There are several ways for Members to keep abreast of Conference activities
and W3C's role at the conference. WWW6 itself publishes extensive information
about registration, schedules, and accepted papers at its
<A HREF="http://www6conf.org/">own site</A>. Registered attendees will have
access to even more WWW6 information, agenda planning tools, and discussion
groups through a new <A HREF="http://ice.www6conf.org/">Interactive Conference
Environment (ICE)</A>, part of the organizing committee's commitment to wiring
the conference itself.
<P>
Rohit Khare, khare@w3.org, is W3C's primary contact for WWW6 activities.

<I>Presented by: Jean-Fran&ccedil;ois Abramatic</I> 11:00 - 11:45<BR>
W3C Chairman Jean-Fran&ccedil;ois Abramatic's keynote will
launch the World Wide Web Consortium Track at WWW6. This talk will highlight
W3C's mission and unique role in the Web Community. The Consortium
has continued its wide-ranging development efforts and global
expansion since WWW5 last year in Paris. W3C's internal processes
have been strengthened, too. This keynote, and the entire W3C
Track, is our 'Annual Report' to the Web Community. We expect

<I>Presented by Vincent Quint</I> 11:45 - 12:30<BR>
The W3C User Interface Domain seeks to improve all user/computer communications on the Web. In particular, this Domain is working on formats and languages that will present information to users with more accuracy and a higher level of control. This Domain includes the Markup (HTML), Style Sheets, Graphics, Fonts, Internationalization, and Amaya activity areas. Questions about the whole range of UI issues are welcome.

<B>Leading the Evolution of HTML</B></A> [<B><A HREF="http://www.w3.org/pub/WWW/Talks/9704WWW6-HTML/">slides</A></B>]<BR>
<I>Presented by: Dave Raggett, Arnaud Le Hors, Rob Miner</I> 2:00 - 2:45<BR>
HTML is a data format for exchanging documents on the Web. It provides
interoperability between a number of products that cover a wide range of
applications: word processing, collaborative
authoring, data base publishing, interactive applications, and more.
There is perhaps no more controversial area in Web standards than HTML
extensions. W3C plays a vital role in the evolution of HTML by both stimulating
development in critical directions and providing a forum where competing
parties can meet to reach a consensus about new features.Among the extensions
currently under discussion by W3C are rich forms, scripting,
frames and subsidiary windows, and mathematical markup.

<I>Presented by: H&aring;kon Lie, Chris Lilley</I> 2:45 - 3:30<BR>
On the Web, content providers do not have the control they have in print media over color, text indentation, positioning, and other aspects of style. A style sheet language offers a powerful and manageable way for authors, designers and typographers to create the rich visual effects. In December 1996, Cascading Style Sheets, level 1 (CSS1) became a W3C Recommendation. This core specification is being built upon to also support absolute positioning and layering, aural presentation (using a speech synthesizer), improved font capabilities, and better printed output.

<I>Presented by Vincent Quint, Ir&egrave;ne Vatton</I> 4:45 - 5:30<BR>
Amaya has been designed as a new generation of client software that
can integrate all aspects of the Web and still remains user friendly.
The main purpose of Amaya is to serve as a testbed to experiment new
Web protocols and formats, to test and demonstrate new features
proposed for existing Web standards. This presentation will review the
design goals, the user experience with the current version and the
future directions for this W3C effort.

There is good reason to come to some common agreement among those concerned with payment processing on how customers can be presented with their various options when making purchases on the Internet.
We feel that customers are more concerned with whether they can pay with a particular "brand" or type of payment vehicle then which protocol they use to process the payment.

<I>Panel Discussion with Bert Bos, H&aring;kon Lie, M.T. Carrasco Benitez, European Commission (on leave) </I> 11:00 - 11:45 <BR>
Having a single system that can deal with all languages and all cultures
of the world has many advantages: when the same protocols and data formats
are used everywhere, different cultures can use the same software everywhere.
Of course, software should still be
localized, to make sure that the user interface is understandable and respects
local culture.
The panel will discuss these issues and present W3C's current efforts
and future plans.

<I>Presented by: Daniel Dardailler</I> 2:00 - 2:45<BR>
<I>Santa Clara Convention Center Room 203/4</I><BR>
This is a report on JEPI, Phase 1, a joint effort of W3C and CommerceNet to explore the process that takes place, typically, after shopping and before actual payment begins. This is the point in time where the exact payment instrument (credit card ala SET, debit card, electronic check, electronic cash, etc.) must be agreed upon between the browsing client and the merchant server, and the transaction can take place. The core technology behind JEPI is of a set of HTTP extensions called PEP and UPP that provides "automatable payment selection" and ultimately enhances the user shopping experience.<BR>

<I>Presented by: Paul Resnick, AT&T Research </I> 2:00 - 2:45<BR>
PICS started as an industry-wide response to attempts to regulate
content on the Internet. It has evolved into a pair of W3C Recommendations
that allow content to be labeled in machine-readable form. It provides for both self-labeling (by the author
or publisher) and third party labeling. PICS is "value-neutral" in the sense that
it does not specify the labeling system, just their format and how they can
be transmitted. The PICS work is now entering a second phase, in which the
infrastructure created to support the initial goal (content filtering) is being
proposed to handle searching and privacy protection tasks which involve content labels.

Access to the World Wide Web by people with disabilities could be

<B>Web Communities</B>: Privacy, Property, Propriety, and Public Policy</A><BR>
<I>Presented by: Joseph Reagle</I> 4:45 - 5:30 <BR>
The Web's success is drawing attention from outside its immediate technical
and user community. Governments realize that a significant portion of their
constituencies and markets are moving online. Furthermore, as the
sophistication of one's interactions on the Web increase, so does its
resemblance to the "real world." Consequently, regulators are interested
in extending their "real world" mandates on commerce, culture, gambling,
money laundering, taxation, data protection, and intellectual property
rights to the Web. However, the outcome is often confusing
because the applied notions of identity, time, relationships, and
location (jurisdiction) do not map to cyberspace. Any resulting fear,
uncertainty, or doubt prevents the Web from growing as quickly
as its potential merits. W3C is establishing a Public Policy Interest Group
as a forum for discussing all of these issues.

RFC 2068, HTTP/1.1, is now a Proposed Standard.
As part of the standards process, it's important
that implementors review the specification against
their own experience to ensure that the
specification actually forms a basis for
higher performance and more reliable Web
interactions.
<P>
The panel will discuss issues with the
HTTP/1.1 specification, the current set of
problems and issues, answer questions from
the audience and take feedback on the HTTP/1.1
work.

Pixel-based graphics have served us well, but have limitations. They don't print well, they don't resize for different displays and they take way too long to download and display. Scalable graphics promise to solve these problems and provide improved interactive response. This panel discussion will examine the strengths and weaknesses of several scalable graphics formats to discover how they might provide a richer graphical environment in tomorrow's Web.

<BLOCKQUOTE>
Commerce over the Internet is founded in the common currency of Commerce anywhere else: trust. Of course, on the Net, traditional questions like Who do you trust? are complicated by virtuality: Do you trust who this is? Looking further out, reliable electronic commerce requires trust in Web content: price lists, downloaded applications, and access control.
<P>
The concepts behind generic "trust management" can be an effective tool for web developers answering these questions today. TM promises generic tools for answering questions like "Do I believe this applet is safe to execute?", "Do I believe X is the author of this document?". W3C has been investigating this area and will discuss some preliminary concepts in this area.

<BLOCKQUOTE>
The key to automatable trust decisions is a trusted machine-readable statement. The W3C Digital Signature Initiative is developing new schemes for digitally signing statements about ownership, reliablity, and more. DSIG's Signature Labels differ from previous digital signature techniques in exactly two ways. First, they allow the signature to carry with it machine-readable assertions and endorsements ("I wrote this and it requires 16 meg of memory"). Second, they allow the data to be separate from the signature, so that third parties can make assertions about data they do not possess ("That applet, written by Company X, can be used by employees in the Accounting Department and has been certified for their use by our IT Department").

Presented by: Jean Paoli & Scott Issacs, Microsoft<BR>
Westin Alameda Room<BR>
<BLOCKQUOTE>
This talk is a detailed walk-through of the Dynamic HTML Object Model in
IE4. The Dynamic HTML Object Model in IE4 is based on the early work of
the DOM working group. The DOM working group is creating a language
neutral, platform independent model that encapsulates the entire HTML
document, all elements, all style, and all the content as objects. These
objects can be manipulated at any time to change the shape and
appearance of the document.
<P>
In addition, Dynamic HTML exposes a rich event model supporting events
on every element in the document. Through these events, the author is
notified of all interactions with the document. New concepts such as
event bubbling and sub-classing elements using the event model will be
discussed.
<P>
The talk concludes with an introduction to data binding. Data binding
allows client-server like web pages to be constructed where the data can
be downloaded and manipulated locally on the client, without continually
needing to return to the server.
<P>
Overall, Dynamic HTML is about providing authors and developers with the
ability to create high performance, interactive web-applications that do
not require a large number of round-trips to the server.

The complementary role to be played in the future by HTML+CSS for some
applications and XML+DSSSL for others is sketched out, and then
further alternatives are constrasted: HTML+JavaScript, XML+CSS, and
XML+Java.

Presented by: Jim Cunningham, Netscape; Respondent: Ralph Swick<BR>
Ballroom E<BR>
<BLOCKQUOTE>
The past two years have witnessed the development of a new class of distributed authoring tools which allow remote editing followed by a network save. Unlike existing tools which save their work to a local filesystem and ignore how web content is made accessible, distributed authoring systems directly employ the HyperText Transfer Protocol (HTTP) to put web content on a server. This allows web content to be edited hundreds or thousands of miles away from the server which distributes it, and gives users the ease of pushbutton publishing.
<P>
The Internet Engineering Task Force (IETF) has just created a new working group to develop an interoperability specification for performing distributed authoring and versioning on the Web. This talk will provide a brief history of Web distributed authoring and versioning to date, and will give an overview of the functional requirements and technical approach under consideration by the WEBDAV group.

Tim Berners-Lee proposed the World Wide Web in 1989, and was joined on the project by his colleague Robert Cailliau in 1990. Tim wrote the code for the Web much as we know it today in the fall 1990. Tim will demo the first browser in the world, his original GUI NeXT browser-editor from that year, on his original NeXT cube. He will discuss his early vision of the Web, which included many features since reinvented (multimedia capabilities, server APIs, intranets, fuller implementation of SGML standards, virtual pages, etc.) and many which remain "lost". He will also show Enquire Within, his proto-Web program of 1980.

Jean-Francois Groff joined the Web project in early 1991, and worked with Tim Berners-Lee to design and implement significant portions of the Web's architecture. Jean-Francois started www-talk in 1991, the online mailing list which served as the central "forum" for the early years of the Web's development. He also helped start the Virtual Library, a forerunner of Yahoo. In 1992, Jean-Francois founded InfoDesign, the world's first Web services firm. Jean-Francois will discuss in detail many of the now "lost" features he developed with Tim in the very early 1990s.
