    (transaction systems, message relays, and bar
    code technology)
  • 1989, World Wide Web

Facts
  • 1994, Tim Berners-Lee founded the World Wide Web
    Consortium (W3C) at MIT

    with symposia about the history and future of the
    Web and W3C

  • Oct 1996 - First W3C Recommendation published is
    Portable Network Graphics
  • Dec 1996 - Separating content from structure,
    CSS Level 1 is published
  • Dec 1997 - HTML 4.0 adds tables, scripting, style
    sheets, internationalization, and accessibility
    features to Web publishing
  • Aug 2000 - Scalable Vector Graphics (SVG) 1.0
    enriches Web graphics
  • May 2003 - W3C adopts royalty-free Patent Policy

7
Achievements (Continued)
  • March 2004 - W3C gives voice to the Web with
    VoiceXML 2.0
  • Feb 2005 - Character Model brings unified
    approach to using characters on the Web
  • May 2005 - Mobile Web Initiative launched to
    facilitate mobile Web access

W3C Process Document
  • Describes
  • Organizational Structure
  • How W3C Functions
  • Does not describe
  • Public interactivity
  • W3C Team internal workings

9
Process Overview
  • Working Draft (WD)
  • Last Call Working Draft
  • Candidate Recommendation (CR)
  • Proposed Recommendation (PR)
  • W3C Recommendation

10
Notes
  • Receive the attention of W3C personnel, yet have
    no official standing
  • Notes from a number of sources
  • Working Groups in Trial Phase
  • W3C Member Organizations
  • W3C Staff

11
Working Draft
  • Published every 3 months
  • Attains Last Call status when near completion

12
Candidate Recommendation
  • Final Draft
  • Submitted to developers for Testing/Implementation
  • Special Circumstances

13
Proposed Recommendation
  • Revised Final Draft
  • Working Group Members cast ballots on their
    acceptance or revision.

14
Recommendation
  • Voted in
  • Considered stable

15
Structure
  • Director
  • Members
  • Advisory Committee
  • Team
  • Advisory Board
  • Technical Architecture Group
  • Working Groups

16
Working Groups
  • Do most of standards development
  • Document development process
  • Focus
  • Degree of membership disclosure
  • Consensus

17
CSS
  • Short for Cascading Style Sheets, a feature added
    to HTML that gives both Web site developers and
    users more control over how pages are displayed.
    With CSS, designers and users can create style
    sheets that define how different elements, such
    as headers and links, appear. These Style Sheets
    can then be applied to any Web page.

18
PNG
  • Portable Network Graphics - A file format for
    bitmapped graphic images approved by the World
    Wide Web Consortium as a replacement for GIF
    files. GIF files use a patented data compression
    algorithm PNG is patent- and license-free.

19
RDF
  • A set of rules (a sort of language) for creating
    descriptions of information, especially
    information available on the World Wide Web. RDF
    could be used to describe a collection of books,
    or artists, or a collection of web pages as in
    the RSS data format which uses RDF to create
    machine-readable summaries of web sites.

20
XML
  • Extensible Markup Language is a W3C initiative
    that allows information and services to be
    encoded with meaningful structure and semantics
    that computers and humans can understand. XML is
    great for information exchange, and can easily be
    extended to include user-specified and
    industry-specified tags.

21
Why Should We Listen to the W3C Recommendations?
22
Here are just a few reasons
  • Adobe Systems Inc.
  • America Online, Inc.
  • Apple Computer, Inc.
  • ATT
  • The Boeing Company
  • British Broadcasting Corporation
  • Canon, Inc.
  • Cisco Systems
  • Daimler Chrysler Research and Technology
  • Google, Inc.
  • HP
  • Hitachi, Ltd.
  • IBM Corporation
  • Macromedia
  • Microsoft Corporation
  • Mozilla Foundation
  • Nokia
  • Novell, Inc.
  • Opera Software
  • Oracle Software
  • SEMANTIC SYSTEMS, S.A.
  • Sun Microsystems, Inc.
  • Walt Disney Internet Group
  • Yahoo!, Inc.

23
But why do they listen to the W3C?
  • Because a standards body is the only way to keep
    internet technologies from being fragmented.
  • It is better for customers and users of the
    internet.
  • Because they are members.

24
But why do they want to members?
  • Communication, project management, accounting,
    advertising, and security.
  • Web technologies are the very heart of many
    organizations.
  • Companies need that part of their organization to
    be stable, and want to have a say in how it
    evolves.

25
Why not the IETF?
  • When Tim Berners-Lee took HTML to the IETF it
    didnt work out.
  • The IETF has traditionally been for lower
    middle-ware.
  • Its method for standards is thorough but not very
    efficient.
  • Practical for critical low level standards, but
    not for upper level standards.
