The Read/Write Web: 

The Read/Write Web The idea was that anybody who used the web would have a space where they could write and so the first browser was an editor, it was a writer as well as a reader. Every person who used the web had the ability to write something. - Tim Berners-Lee Copyright © 2007 All Rights Reserved

The End of the Web Page Paradigm: 

“Web content is external rather than internal. Instead of a website being a “place” where data “is” and other sites “link to”, a site is a source of data to be remixed collectively both internal and external to a given “site””. The End of the Web Page Paradigm Copyright © 2007 All Rights Reserved

The End of the Web Page Paradigm: 

The End of the Web Page Paradigm The page is no longer the atom of the web Linking being replaced by syndication (RSS) Content is more important than the container Home Alone?

Web Standards: 

The World Wide Web Consortium (W3C), along with other groups and standards bodies, has established technologies for creating and interpreting web-based content. These technologies, which we call “web standards,” are carefully designed to deliver the greatest benefits to the greatest number of web users while ensuring the long-term viability of any document published on the Web.

Web Development – Historical Perspective: 

Lack of Browser Support for CSS Graphic Design vs. User Interface Design Using Tables to format Layout Spacer GIFs Invalid Code and Hacks Web Development – Historical Perspective Copyright © 2007 All Rights Reserved

What are the Standards?: 

What are the Standards? Structural Languages HTML 4.01, XHTML 1.0, XHTML 1.1, XML 1.0 Presentation Languages CSS Level 1, 2, 3; MathML; SVG Object Models DOM Level 1, 2, 3 Core Scripting Languages ECMAScript 262 (standardized JavaScript) Copyright © 2007 All Rights Reserved

Advantages of Using Standards: 

Simpler development and maintenance Compatibility with future web browsers Faster download and rendering of web pages Better search engine rankings Separate content from presentation Semantic markup Better accessibility Advantages of Using Standards Copyright © 2007 All Rights Reserved

Lessons Learned: 

Provide alternatives, both online and offline Understand the web accessibility is a continuum Focus on the low hanging fruit Avoid the accessibility vs. design war Educate instead of mandate Code to standards and you are ¾’s of the way there Copyright © 2007 All Rights Reserved Lessons Learned
