Web 3.0 is a term that has been coined withdifferent meanings to describe theevolution of Web usage and interactionamong several separate paths.

These include transforming the Web into adatabase, a move towards making contentaccessible by multiple non-browser

applications, the leveraging ofartificialintelligence technologies, the Semantic

web, or the Geospatial Web.

Web 1.0: Web Browser driven "Interactive Web ofHypertext" pages where presentation, logic, and data areindistinguishable

Web 2.0: Web Services based API driven "Web ofservices" that separate "Application Logic" from theintermingled presentation, logic, and data pages of Web1.0. Examples of Web 2.0 application profiles include: the

use of Ajax . Web 2.0 does not explicitly expose DataModels.

Web 3.0: The final step in the decomposition ofmonolithic Web Pages into discrete componentsthat include the Presentation (HTML and(X)HTML), Logic (Web Services APIs), and Data

(Data Models) trinity, it transitions Webcontainment from Web Pages to Web Data. Itsemergence simplifies the development anddeployment of Data Model driven compositeapplications that provide easy, transparent and

organized access to the worlds data,information, and knowledge

WWW now

Humans do everything

Computers as tools

Problems abound

WWW in the future

Computers do a lot

more Computers work on our

behalf

Problem: Web was built for humans

Human interpretation needed to understand content (it

does not scale)

It is particularly difficult to automate unforeseen situations

Rough solution: make the Web friendlier for

machines

We need machine-understandable content (not machine-readable, we already have that)

(note: by machine-understandable we mean content withaccessible formal semantics)

The Web is more than just a library

Think of it as infrastructure for services & functionality

XML provides an elemental syntax for content structurewithin documents.

XML Schema is a language for providing and restricting

the structure and content of elements contained withinXML documents.

RDF is a simple language for expressing data models,RDF-based model can be represented in XML syntax.

RDF Schema is a vocabulary for describing properties

and classes of RDF-based resources. OWL adds more vocabulary for describing properties and

classes:

First we download the web pages from the web .

Then embedded the semantic information into them

It consist of two parts

1.The web information between rdf_discription &/rdf_discription

2.The information between ontopath &/ontopath
