Web 1.02.03.0 Good.ppt

Agenda
 Web 1.0
 Web 2.0
 Web 3.0

Web 3.0
Before describing web we need to understand one
thing very clearly

Web ≠ Internet
World Wide Web ≠ Internet Service
We must remember that both are not the same
Web is different then Internet

World Wide Web
 The world wide web is larger
collection of interconnected
Documents or Content
 facilitates communication
between people …..and also
computers

World Wide Web
 Web based on Hypertext
 Also based on client/server model
Web
Service
Request
Response
Web Client
(browser)

Internet
The Internet is the collection of
interconnected computer Networks.

Move to First Part
Web 1.0
Web 1.0 is an old internet that only allows people to read from the
internet.

Web 1.0
 First stage of the World Wide linking web pages and
hyperlink
 Most read-only Web. It focused on companies home pages
 Dividing the world wide web into usable
directories
 It means Web is use as “Information Portal”

Web 1.0
 Everyone has their personal own little corner in the cyberspace
 It started with the simple idea “Put content together”
 Media companies put content in the web and pushes it to user.
using web 1.0 Companies Like BBC,CNN able to get online.

Web 1.0
 Web 1.0 gives us Information exclusivity, It means be the first to own the
content
 Geocities era was all about read-only content and static HTML sites
 People preferred navigating the web through link directories of Yahoo!
And dmoz.

Web 1.0
Technical Aspect
 Looking from the technical perspective, Web 1.0 solutions requires no or
very less scripting. So this implies that simple HTML and image editing skills
are enough for web 1.0 development.
 It uses framesets.
 It use tables to position and align elements on a page.
 HTML extensions such as the <blink> and <marquee> tags introduced
during the first browser war

Web 1.0
Web 1.0 Key points are:-
• Any thing can link to anything
• Device and Software Independence
• Resource identifies by its address. http://twitter.com/IT
• Access to content resource via protocol ( Get ,Post, Put, Delete)

Web 1.0
 Recourses or Document must be include Markups.
Languge:-
HTML (Hyper Text Markup Language)
First Markup Language.HTML is the basic building-blocks of web
pages. It is a set of markup tags, and HTML uses markup tags to
describe web pages.
<html><head>..</head><body>…</body><html>

Web 1.0
Few Myth
So People made few myths about Web 1.0:-
 Most questionable is the interface
 Most challenging is the content
So then we get Web Application

Web 1.0
Web Application
 A web application is any application that uses a web browser as a client.
The application can be as simple as a message board or a guest sign-in
book on a website, or as complex as a word processor or a spreadsheet.
 A web application relieves the developer of the responsibility of building a
client for a specific type of computer or a specific operating system
 Web Application = Interface +Content (Data)
Amazon, Expedia, Kartoo, PHPMyAdmin, webmin,…

Web 1.0
Sad Facts
 Read only Web
 Limited user interaction
 Keyword based (dumb) search ------ Web Directories
 The Lack of standards -------Browsers war

Next Step
When we got a grip on the technical part, web became clearer and then
we discover
 Power of Networks
 Power of Links
 Power of Collaboration
 Power of content and reach
 Power of Friends

WEB 2.0
And then the Next step is

A TERM USED TO DESCRIBE A NEW GENERATION OF WEB SERVICES AND
APPLICATIONS WITH AN INCREASING EMPHASIS ON HUMAN COLLABORATION.
Web 2.0

Web 2.0
 It is a platform that gives users the
possibility (liberty) to control their
data.
 This is about user-generated
content and the read-write web.
 People are consuming as well as
contributing information through
blogs or sites like Flicker,
YouTube, Digg, etc.

Principles of Web 2.0
No Products but Services
 “There are no products, only solutions”
 A problem solving approach
 Must Provide Simple Solutions

Principles of Web 2.0
Customization
 Every individual is unique
 Some people want to be different
 Allow him to choose instead of forcing him to use what you have made
 Make him feel home
e.g. My yahoo, Google Homepage, MySpace , Firefox extensions

Web 2.0
Concepts
Web 2.0 can be described in 3 parts which are as follows:
 Rich Internet Application (RIA) - It defines the experience brought from
desktop to browser .whether it is from a graphical point of view or usability
point of view. Some people relate RIA with AJAX and Flash.
 Service-oriented Architecture (SOA) - It is a key piece in Web 2.0 which
defines how Web 2.0 applications expose its functionality so that other
applications can integrate the functionality and produce a set of much richer
applications (Examples are: Feeds, RSS, Mash-ups)

Web 2.0
Concepts
Social Web – It defines how Web 2.0 tend to interact
much more with the end user and making the end
user an integral part.

Web 2.0
Social Web
 A third important part of Web 2.0 is the Social Web. The term is currently
used to describe how people socialize or interact with each other throughout
the Web .
 The social web consists of a number of online tools and platforms where
people share their perspectives, opinions, thoughts and experiences
 Web 2.0 Applications tend to interact much more with the end user. As
such, the end user is not only a user of the application but also a participant

Web 2.0
User can participate by :-
 Podcasting
 Blogging
 Tagging
 Contributing to RSS
 Social bookmarking
 Social networking

Web 2.0
Technologies
The client-side/web browser technologies used in Web 2.0 development are :
Ajax(Asynchronous JavaScript +XML)
Ajax programming uses JavaScript to upload and download new data from the
web server without full page reload.
Adobe Flex
Flex makes it easier for programmers to populate large data grids, charts, and
other heavy user interactions. Applications programmed in Flex, are
compiled and displayed as Flash within the browser

Web 2.0
Web 1.0
 The mostly read only Web
 45million global user(1996).
 Focused on companies
 Home pages
 Owning content
 HTML,portals
 Web forms.
 Netscape
 Page views
Web 2.0
 The widely read -write web
 1 billion + global user(2006)
 Focused on communities
 Blogs
 Sharing content
 XML,RSS
 Web Application
 Google
 Cost per click

Web 2.0
Sad Facts
 Same old Keyword based search.
 Web application are still rigid
 Each Website have its own data and it is not sharing it.
 Computers can not understand any thing
 Web 2.0 is Social change. The technical part has not changed much

Introducing New Kind of Web
Main Reasons
 How will our information be organized.
 Will we still do the “surfing” or will the machine surf for us

New Concept Is Web Of Data
Beyond the present Web Lets move towards the web
of Data

Web Of Data
New kind of Web capable of reading and understanding content and
context.
When the web can understanding content it can better satisfy the request of
people and machines.

Web 3.0 (New Big Thing)
Semantic Web
 It is a Web of data.
 changing the web into a language that can be read and categorized by the
system rather then humans.
Artificial Intelligence
 Extracting meaning from the way people interact with the web.
Mobility
 everything, everywhere, all the time

Web 3.0
Ingredients:
RDF(Resource Description Framework)
 Language for representing information about resources in the World Wide
Web.
 Defining & describing data and relationship among data.
 RDF is based on the idea of identifying things using Web identifiers which
is called Uniform Resource Identifiers, or URIs

Web 3.0
In computing, a Uniform Resource Identifier (URI) is string of characters used
to identify a name or a resource on the Internet.
e.g
PHP is programing Language
POWL is an application written in PHP
It use triple {subject,property,object} model
hasWebSite(“#php”,”http://www.php.net/”)
isA(“#php”,”#language”)
isWrritenIn(http://powl.sf.net/,”#php”)
It is all about triple of URIs

Web 3.0
Ingredients:
 OWL(Web Ontology Language)
 With RDF Scheme we can define concepts and make simple relations
between them.
 But, RDF scheme is limited. A language needs more expression and logic
to make good reasoning possible.
 That’s why OWL (The Web Ontology Language) was invented.
 Its mean to reason you need rules

Web 3.0
I got this stamp from my uncle

Web 3.0
The rule for calling someone my uncle is that one of my parents has a brother.
mother or father
son of brother
I
Rules are formulated in SWRL (Semantic Web Rule Language).

Web 3.0
<ruleml:imp>
<ruleml:_rlab ruleml:href="#example1"/>
<ruleml:_body>
<swrlx:individualPropertyAtom swrlx:property="hasParent">
<ruleml:var>x1</ruleml:var>
</swrlx:individualPropertyAtom>
<swrlx:individualPropertyAtom swrlx:property="hasBrother">
swrlx:individualPropertyAtom swrlx:property="hasBrother">

</ruleml:_body>
<ruleml:_head>
<swrlx:individualPropertyAtom swrlx:property="hasUncle">
</ruleml:_head>
</ruleml:imp>

•
So, In Web 3.0
 Words in XML
 Grammar in RDF (scheme) and OWL
 Rules in SWRL
