Web 2.0 Introduction

Web 2.0, a phrase coined by O'Reilly Media in 2004,refers to a perceived or proposed second generation ofWeb-based services

The last, compact definition of Web 2.0, according toTim O'Reilly is this one: Web 2.0 is the businessrevolution in the computer industry caused by the moveto the internet as platform, and an attempt to understandthe rules for success on that new platform. Chief amongthose rules is this: Build applications that harnessnetwork effects to get better the more people use them."

particularly for software

Key Principles of Web 2.0 -1

the web as a platform

data as the driving force

network effects created by anarchitecture of participation

innovation in assembly of systems andsites composed by pulling together

features from distributed, independentdevelopers (a kind of "open source"development)

4 Levels of Web 2.0 Applications

Tim O'Reilly gave examples of levels in the hierarchy of Web 2.0-ness:

Level 3 applications, the most "Web 2.0", which could only exist on the Internet,deriving theirpowerfrom the human connections and network effects Web 2.0 makespossible, and growing in effectiveness the more people use them. O'Reilly gives asexamples: eBay, craigslist, Wikipedia, del.icio.us, Skype, dodgeball, and Adsense

Level 2 applications, which can operate offline but which gain advantages from goingonline. O'Reilly cited Flickr, which benefits from its shared photo-database and fromits community-generated tag database

Level 1 applications, also available offline but which gain features online. O'Reillypointed to Writely (since 10 October2006: Google Docs & Spreadsheets, offeringgroup-editing capability online) and iTunes (because of its music-store portion)

Level 0 applications would work as well offline. O'Reilly gave the examples ofMapQuest, Yahoo! Local, and Google Maps. Mapping applications usingcontributions from users to advantage can rank as level 2.

non-web applications like email, instant-messaging clients and the telephone

Web 1.0 was all about connecting people. It was an

interactive space, and I think Web 2.0 is of course a

piece of jargon, nobody even knows what it means.

If Web 2.0 for you is blogs and wikis, then that is people

to people. But that was what the Web was supposed tobe all along. And in fact, you know, this 'Web 2.0,' it

means using the standards which have been produced

by all these people working on Web 1.0.

--Tim Berners-Lee, August 2006

What is Web 2.0? (1/2)

A marketing term, a buzzword, but moreover anATTITUDE

Shifts 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 movearound


12/19

What is Web 2.0? (2/2)

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 iscategorized and manipulated

User agent becomes a fat rather than thin client

Requires a new set of tools to aggregate and remix

microcontent in new and useful ways


13/19

Properties of the 2.0

Generation Low Barrier

Self-Service

Networked Cost-Effective

Open

Decentralized


14/19

The Big Ideas in Web 2.0

1. Write semantic markup and scatter

microcontent (transition to XML)

2. Provide Web services (move away from place)

3. Shift to programming (separation of structureand style)

4. Users contribute content and metadata (social

networks)5. Rich user interfaces (users are in control)

6. Re-use of content (remixing when needed)

16/19

Consider All the Ways That Users

Can Contribute Content

People (not just Web sites) can/have become entitieson the Internet

Its not just people using data, but people developingcapabilities

Users contribute to the content of Web sites

Not to be confused with user-centered design

More like collaborative authoring

Not just with blogs, wikis, annotation, tagging, rating,etc. (e.g., xFolk)

Some of these tools blend into the background


17/19

Rich User Interfaces

Not just about Ajax, client-side scripting

Goal: Make user feel that the interface is exclusively for

them

Customized

Directly manipulated

Fast

Problems

Accessibility

Security, privacy


18/19

Content Re-use

Started with Google Maps and Google Hacks

Mashups draw on multiple data sources to

create rich Web applications

Typically built on APIs and XML content

Reduced development cost and increased user

satisfaction

Numerous mashup toolkits Expected to hit maturation in 2 years (Gartner

Group)
