PREFACE

W eb 2.0 is a term describing changing trends in the use of World Wide

Web technology and web design that aims to enhance creativity, secureinformation sharing, collaboration and functionality of the web.

W eb 2.0 concepts have led to the development and evolution of web-

based communities and its hosted services, such as social-networking

sites, video sharing sites, wikis, blogs, and folksonomies. The term

became notable after the first O'Reilly Media Web 2.0 conference in

2004.

Although the term suggests a new version of the World Wide Web, itdoes not refer to an update to any technical specifications, but to changes

in the ways software developers and end-users utilize the Web.

According to Tim O'Reilly:

8/8/2019 Web 2.0 & Web Blog


W eb 2.0 is the business revolution in the computer industry caused by the

move to the Internet as platform, and an attempt to understand the rules

for success on that new platform.

Web 2.0 is hot, controversy, and maybe the (Internet world) buzzword of 2005.

We are going to examine what is being meant with Web 2.0, meaning

why there is huge agreement on the fact that present changes have

something in common which is different or new. We will identify this by

examining the technologies and applications said to be Web 2.0

One technology that was of major influence, and is of major significance

for Web 2.0,is called AJAX and will thus be examined in a particularly

detailed way. Finally, we will try to capture the significance of Web 2.0 :

How successful are the new technologies and applications? How are

major players on the Web reacting? To what extent are they already

involved? Can there be a prediction made about how things will continue

to change in the Web?

WHAT ISWEB 2.0 :-

Everybody is talking about Web 2.0 lately. It's a real hype, but do you know what it is

all about? Web 2.0 refers to the second stage of development of the Internet, accordingto some people. It's about the change of a collection of websites to a complete platform

for interactive web applications for the end-users on the World Wide Web.

For some people it will mean the end of desktop applications. These web-based services

make it easy for people to place things online, such as documents, pictures, movies, to-

do lists... and share them with others by just using your browser. Software is no longer needed. Everything happens online: sharing information, collaborating etc. It's a social

happening. People are organizing and sharing their lives on the Web.

Web 2.0 is a social phenomenon that gives users freedom to share and re-use, that uses

technologies such as social bookmarking, weblogs, podcasts, RSS Feeds, wikis... The

users are the force behind the Internet, we make the Web every day. We publish pieces

of our lives, day after day. The new thing about Web 2.0 is that all this sharing of

personal information is so much easier and more attractive than it used to be.

Information from different websites can easily be combined for you to make it easy to

track it, or even better the new information, based on your own preferences, will bedelivered to ou.

The key principles of the new Internet and its web-applications are:

The main force is data

The World Wide Web is being used as a platform.A lot of people participate which causes an architecture of participation and

democracy.

Features from lots of independent developers are being combined and

assembled together to create innovative sites and systems

The perpetual beta.User-friendly, rich and interactive interfaces:

The Internet is a Read/Write Web.

Have faith in users

Web 2.0 is a great thing, but it is under constant development. It still needs

much work. Structures need to evolve to more similar structures, so that alldevelopers will find it easy to work and collaborate with other developers.

People will need to be sharing their knowledge. Web 2.0 can only evolve when

working in teams. More brains working together mean more ideas. More ideas

lead to more innovations. One thing is for sure: we haven't seen the last of Web

2.0 yet.

History of WEB 2.0:-

The term Web 2.0was created by the publisher Tim O¶Reilly together with

work partners in October 2004, as various sources concordantly state,amongst them O¶Reilly himself [O¶R05]. They then also held the first Web

2.0 Conference, with its successor in this autumn.

In the past months, Web 2.0 has been a hot topic for discussion, especially

in the blogosphere1, and this has also lead to first coverage in the so-calledtraditional media.

It is meant to summarize new technologies, applications, concepts, ideas

and realizations in the World Wide Web. These vary from author to author;

the term of Web 2.0 is not a well-defined one, and we can only examine a

selection here. This term consists of the word Web and the version number 2.0, so this implies that there exists at least one earlier version as a

predecessor ± the so-called Web 1.0.

Characteristics

According to Best, the characteristics of Web 2.0 are: rich user experience, user

participation, dynamic content, metadata, web standards and scalability. Further

characteristics, such as openness, freedom and collective intelligence by way of user participation, can also be viewed as essential attributes of Web 2.0.

Rich User Experience

This term relates to the behavior of a Web application. Many new Web 2.0

applications are said to allow Rich User Experience because they behave in a

way very similar to desktop applications. These latter are characterized througha state based user interaction. This means that the application can have differing

states, show progress, and reply fast

standards-based presentation using XHTML and CSS;

AJAX

dynamic display and interaction using the Document Object Model;

data interchange and manipulation using XML and XSLT;

asynchronous data retrieval using XML Http Request;

and JavaScript binding everything together.³

Web 2.0 Design Patterns

The Long Tail

Small sites make up the bulk of the internet's content; narrow niches make up the bulk of

internet's the possible applications. Therefore: Leverage customer-self service and algorithmic

data management to reach out to the entire web, to the edges and not just the center, to the longtail and not just the head.

Data is the Next Intel Inside

Applications are increasingly data-driven. Therefore: For competitive advantage, seek to own a

unique, hard-to-recreate source of data.

Users Add Value

The key to competitive advantage in internet applications is the extent to which users add their

own data to that which you provide. Therefore: Don't restrict your "architecture of participation"

to software development. Involve your users both implicitly and explicitly in adding value to

your application.

8/8/2019 Web 2.0 & Web Blog


Network Effects by Default

Only a small percentage of users will go to the trouble of adding value to your

application. Therefore: Set inclusive defaults for aggregating user data as a side-effect

of their use of the application.

Some Rights ReservedIntellectual property protection limits re-use and prevents experimentation. Therefore:

When benefits come from collective adoption, not private restriction, make sure that

barriers to adoption are low. Follow existing standards, and use licenses with as few

restrictions as possible. Design for "hackability" and "remixability."

The Perpetual Beta

When devices and programs are connected to the internet, applications are no longer

software artifacts, they are ongoing services. Therefore: Don't package up new features

into monolithic releases, but instead add them on a regular basis as part of the normal

user experience. Engage your users as real-time testers, and instrument the service so

that you know how people use the new features.

Cooperate,Don't ControlWeb 2.0 applications are built of a network of cooperating data services. Therefore:

Offer web services interfaces and content syndication, and re-use the data services of

others. Support lightweight programming models that allow for loosely-coupled

systems.

Software Above the Level of a SingleDevice

The PC is no longer the only access device for internet applications, and applications

8/8/2019 Web 2.0 & Web Blog


K ey Aspects of Web 2.0

The Web and all its connected devices as one global platform of

reusable services and data

Data consumption and remixing from all sources, particularly user

generated data

Continuous and seamless update of software and data, often very

rapidly

Rich and interactive user interfaces Architecture of participation that encourages user contribution

Web 1.0 technologies were platform-based whereas Web 2.0

offers the web as a platform. T hat is to say, old web companies

offered products you could run on your Windows, Mac, or Linux computer; the new generation of web companies offers services

which are delivered on the web itself.

How Web 2.0 Will Change the Internet

I personally feel that it is an understatement to say that Web 2.0 will change the face of the Internet.

It is an emerging technology that has a number of important implications, and those who are

prepared for such implications will prosper. Many have said that Web 2.0 will give users the same

experiences that they first had when they used the Internet for the first time.

However, many experts feel that Web 2.0 will be the result of small advances and tweaks that will

gradually transform the net. While it took a few years for email to be adopted by the general public,

many feel that Web 2.0 will allow things to move much faster. However, the revolution that will

become Web 2.0 is much more quiet than previous revolutions.

To the casual Internet user, the changes are not all that obvious. They log on, go to their favorite

websites, or download games or movies. However, there are a large number of technical advances

that are being made each day, and it will take some time for these changes to become visible. One

of the reasons why Web 1.0 was so powerful was because of its simplicity. Unlike many

technological marvels, it was not inherently complex. A website was simply a group of pages that

had text and images, and if you found a website that was similar in topic to your own, you couldlink to them, and they could link back.

People who visit their website could come to your website, and people who came to your site could

go to theirs. While this interaction was very simple, it was revolutionary, and laid the foundation for

what we have today. Now that I've given you an illustration of Web 1.0, let me give you a

demonstration of web 2.0.

8/8/2019 Web 2.0 & Web Blog


Let¶s say you have a website in Web 2.0 that is related to a specific dog

breed. You could subscribe to a dog care service that is related to Google

News, and you could put in a request for the service to scan numerous

new outlets across the web, and notify you of any information that isrelated to a specific dog breed. When you get up in the morning, you

could find a link to a book that is written about the dog breed of your

interest.You could then click on the link to go to the first article, and you could then use a tool

such as Blogger to write a review of the books with links to Amazon.com, a placewhere the book could be purchased.

Common Web 2.0 ToolsThere are a number of common tools that are considered to be Web 2.0 technologies.

One of these is a podcast, which is a personal broadcast that can be accessed on

demand. It will generally come in the form of a multimedia file that is distributed over

the Internet. It can be played on portable devices or on a computer. Another type of Web

2.0 technology is a mash up. This is a website or program that collects content from

other parts of the web to turn it into something entirely new. A folksonomy is a method

in which users categorize links or other useful information. When combined, these

technologies are expected to transform the web

Web 2.0 and The Read/Write Web

One of the emerging themes of Web 2.0 is the ability for users to add data to web sites

directly. In Web 1.0 web content was managed by so-called ³webmasters´. The

webmaster would update HTML web pages using simple text editors (like Notepad) or advanced web management systems (like Dreamweaver).

In Web 2.0 web sites are reaching out to the users and inviting them to add content

directly. Wikis, Weblogs (Blogs), Forums, and Content Management Systems are

making this possible.

Wikis (from the Hawaiian ³Wiki Wiki´ meaning ³quick´) are flat web spaces where

users can update existing pages and add their own web pages by doing little more than

clicking a link. In a Wiki, every page has an ³edit´ button and any user can then update

the text that is displayed

AJAX

A popular Rich Client technology is Ajax (Asynchronous Java and XML). Ajax usesJavaScript to send requests for data from the browser directly to the remote server. The

server responds with data in the form of XML. Since the JavaScript is running

asynchronously, the user doesn¶t have to wait for the response to make another request

(as is true of ³Thin Client´ applications). Good examples of this technology are Google

Maps and Google Mail.

WHAT IS BLOG

A blog (a contraction of the term "Web log") is a Web site, usually

maintained by an individual with regular entries of commentary,descriptions of events, or other material such as graphics or video. Entries

are commonly displayed in reverse-chronological order. "Blog" can also

be used as a verb, meaning to maintain or add content to a blog .
