5Web 2.0 definition
- No definitive definition (still evolving)
- Moves the focus to the user of the information,
not the creator of the information - Information moves beyond web sites
- Information has properties and these properties
- follow each other and find relationships
- Information comes to users as they move around
- Information is broken up into microcontent
units that can be distributed over many domains - Interaction is no longer limited to (X)HTML
- Users are able to control how information is
categorized and manipulated - User interface becomes a fat rather than thin
client - Requires a new set of tools to remix microcontent
in new and useful ways - http//oreilly.com/web2/archive/what-is-web-20.htm

RSS (Really Simple Syndication) feeds these are
simple web features

25Web 2.0 Rich user experience
- Goal of Web 2.0 - A Rich User Experience
- Get the user to content they want
- Link the user to content they might want

- Let the user decide how to use the content
- Do all of the above quickly and efficiently
26Web 2.0 Overview
- Transition of websites from isolated information
silos to sources of content and functionality,
becoming computing platforms serving web
applications to end users - Social phenomenon embracing an approach to
generating and distributing Web content itself - Characterized by open communication,
decentralization of authority, freedom to share
and re-use, and "the market as a conversation" - More organized and categorized content, with a
far more developed deep linking web architecture
than before - Shift in economic value of the Web, possibly
surpassing that of the dot com boom of the late
1990s - Has lead to a resurgence of excitement around the
implications of innovative web-applications and
services - Effectively you provide the content!
