3. Evolution of the web from
web 1.0 to web 4.0.
• Web is the largest transformable-information
construct that its idea was introduced by Tim
Burners-Lee in 1989 at first.
• Web 1.0 is the first generation of the web which
according to Berners-Lee, could be considered the
read-only web and also as a system of cognition
4. Web 1.0
• Web 1.0 began as an information place for businesses
to broadcast their information to people. The early web
provided a limited user interactions or content
contributions and only allowed to search the information
and read it.
5. Web 1.0 – the Read Only
Web
• Origins of the Web
Invented by Tim Berners-Lee in 1989
First Web Browser – October 1990
First Web Server – November 1990

•
9. Web 1.0 Apps
• Mostly Read only
• Some interactivity
• Submit forms
• Dynamic Applications
• Problems
• Slow, clunky
• Page needs to refreshed when new info entered
• Session state not handled well
10. Search 1.0 Failings
• Result of Web 1.0 search technology:
• Focused purely on size of index
• Relevance was ignored
• By 1997, only 1 of the top 4 search engines could find
itself!
• Web Search seen as hopeless
• And Google?
Strictly Web 2.0
11. Web 1.0 Search
Technologies
• Characterized by large indexes but crude retrieval techniques
• World Wide Web Worm (WWWW), 1993
• First Search Engine
• Indexed titles and headers only
• Yahoo, 1994
• Human edited directory (still is!)
• WebCrawler, 1994
• First search engine to search the text of the web page
• AltaVista, 1995
- Pinnacle of Web 1.0 technology
• Natural language querying with Boolean operators
• Huge index
12. Where Web 1.0 went
wrong…
• Misunderstood the Web’s dynamics
• Relied on old software business models
• Locked in users with APIs
E.g. Netscape
• Software sold as an application not a service
13. and kept going wrong!
• Ignored their key asset
It’s Data, not the software
• Ignored the power of network effects
The more people use a networked service, the more
useful it becomes
• Saw the Web as publishing, not participation
Read-Write Web, not Read-only Web
14. Web application
• A computer program that runs over the web.
• For example, Google’s Writely is a word
processor that runs over the web and is similar
to Microsoft Word.
15. Web service
• A technical way for web applications to exchange data.
• Web services make mash-ups possible.
16. Surviving Companies were
Web 2.0 all along
• Google, Amazon, EBay
• Why?
• Tapped in to the Web’s dynamics
• dynamics = success
• Fight against them = failure
17. Web 2.0
• Web 2.0 was defined by Dale Dougherty in 2004
as a read-write web . The technologies of web 2.0
allow assembling and managing large global
crowds with common interests in social
interactions.
19. Mashups
• A way to make different applications work together.
For example, you could insert a Google Map in
your website or list and sell books from Amazon in
your blog.
20. Peer-to-peer: Flickr.com
• Flickr
• Allows photo sharing
• Combines, blogs, tags and photo
albums
• Share photos and add
comments, tags, keywords
• Collective Intelligence and
semantic tagging
• Easier to search and access
photos around specific themes,
areas of interest etc.
21. Mashups
• Wikipedia
“A mashup is a website or web application that seamlessly
combines content from more than one source into an integrated
experience.”
Mashup data from the following:
• Amazon Web Services
• Products list, market data
• Google, Microsoft
• Maps, search, Earth, Messaging
• Yahoo
• Images (flickr), music, search, shopping, maps, jobs, traffic,
travel, weather, bookmarks (del.icio.us)
23. Web as the platform
• Google
Docs &
Spread
sheets
24. Web as the Platform: Google Docs &
Spreadsheets
25. Blogs
• Blogs – a blog, or weblog, is an online journal
or web site on which articles are posted and
displayed in chronological order.
. Subject resources, book reviews, library news,
discussion groups
. Blogging software:
http://wordpress.com
http://www.livejournal.com
http://www.blogger.com
26. Wiki
• As with blogs, you can download software so
you can run a wiki on your own website or you
can sign up for a hosted service.
• The hosted service is the easier route and many
are free. A good place to start looking is on
Wikipedia which has a comprehensive article
titled “Comparison of wiki software.”
• If you want a hosted wiki, you can start by
checking out www.wetpaint.com and
www.wikispaces.com.
27. Web 2.0 Tools
• Blogs – a blog, or weblog, is an online
journal or web site on which articles are
posted and displayed in chronological
order.
. Subject resources, book reviews, library
news, discussion groups
. Blogging software:
http://wordpress.com
http://www.livejournal.com
http://www.blogger.com
28. Web 2.0 Tools
• RSS and Newsreaders
. Really Simple Syndication is a technology that
enables publishers to syndicate news and other
contents on the web
Libraries are keeping up to date by subscribing
to news & information sources via RSS feeds.
29. Social Network
• Start a Social Network
• A good way to start a social network would be to create
a space on MySpace, Facebook, Windows Live, or one
of the other offerings listed in the Wikipedia article
mentioned above.
• If you are willing to host and configure your own
software, you can explore some of the open source
offerings such as Drupal (www.drupal.org) and Mambo
(www.mamboserver.com). However, be warned that
setting up one of these sites can be a significant task.
30. YouTube
• YouTube allows users to upload video clips which made
available to other users who can view, rate and comment on
them.
• YouTube makes it easy for people to send out email links of
videos they found interesting, creating a powerful viral
marketing environment.
31. Search Engines
• Web 1.0
AltaVista,
• Web 2.0
Google
• Web 3.0
Google personalized, Semantic Search:
SWSE,
Swoogle, DumpFind, Hakia
36. Client side Technologies
• Asynchronous Javascript and XML (Ajax)
• Adobeflash and Adobe flex framework
• Javascript/ Ajax framework
37. Server side Technologies
• Same technologies like Web 1.0
• PHP, Ruby, Coldfusion, perl, python, JSP and ASP
• Only difference lies in the way the data is formatted. To share
its data with other web sites, a web site generates output in
machine readable formats such as XML , RSS and JSON.
38. Social Networking
• FOAF – Friend Of A Friend
Machine readable ontology describing persons, their
activities and their relations to other people and objects
FOAF – expressed using RDF( Resource Description
Framework)
• XFN - XHTML Friends Network
XHTML Friends Network (XFN) is an HTML microformat
developed by Global Multimedia Protocols Group that provides a
simple way to represent human relationships using links.
39. Web Operating Systems
• EyeOS
2005

42. Web 1.0 2.0 & 3.0
• Hypertext/CGI Web.
• Community Web
• Semantic Web (for machines).
43. Web 3.0
• The term ‘Web 3.0’ was first coined by John Markoff of
the New York Times in 2006
• Web 3.0 is a term, which definition is not confirmed or
defined so far as several experts have given several
meaning, which do not match to each other, but
sometimes it is referred to as a Semantic Web.
46. WEB 3.0
The web 3.0 is also known as the “Semantic web”.
It includes several technologies in order to arrange and structure data you
can find on the internet to make it available and usable by programs and
software thanks to a metadata system. The purpose is to make the web
readable by machines and not only by humans.
It starts with the Resource Description Framework (RDF) which gives the
specifications of such a metadata data model. It is also the Web Ontology
Language (OWL) and notations like RDF Schema (RDFS).
SVG (Scalable Vector Graphics) are between the web 2.0 and the web
3.0. Many websites are already using this technology to display animated
content. Flash animations are already taking advantage of this technology
to deliver advanced animated content without the heavy weight of usual
“movie files”.
47. Web 3.0
“Web 3.0 is a third generation of Internet based Web
services, collectively consists of semantic web,
microformats, natural language search, data-mining,
machine learning, recommendation agents that is
known as Artificial Intelligence technologies or
Intelligent Web.
Web 3.0 is highly specialized information structures,
moderated by a group of personality, validated by the
community, and put into context with the inclusion of
meta-data through widgets”.
49. Mobility
• Currently two different webs:
• Fixed and mobile
• Limited integration between the two
• Need to develop for both types of device
• Reasons:
• Input/output
• Screen size (Max ~2.6 inches)
• Tiny Keyboard, Fat Fingers
• Processing Power
• Max ~350MHz CPUs
51. Web 3.0 Technology
• Apart from cloud-based
technologies, is there
anything else that will
accelerate the adoption of
Web 3.0?
52. Web 3.0 to 4.0
• It is clear that success in the world of Web 2.0 has
stemmed from the understanding of the next
generation of the web, the semantic web or web 3.0
.We are now entering an age of connected data
(Big Data, Open Data, Personal Data are all part of
the story) and if the idea of using the principles of
next generation of technologies to win current
battles has any weight, we need to ask what will
define web 4.0 and how will it shape innovation in
the current age of the web?
53. Web 4.0
• Web 4.0 is often characterised as the WebOS -
the entire web being a single operating system
where information flows from any one point to
any other. It is often defined in technical terms
because technical people are the only ones
thinking about it. I believe that the principle
can go wider and that the WebOS will define
the entire economy, or at least the economic
activity that can be linked to digital technology
55. Open Source Technology
• Richard Stallman worked on a project called
GNU project , a free software foundation for
developing and improving the open source
community on Sep 1983 at MIT.
• The first GNU project was Unix based
operating systems.
56. Licensing in Open source
• GNU offers General Public License (GPL ) as a
license for all open source softwares.
• Recently GPL version 3 is adopted.
• It must be agreed upon by the user while
installing the open source software which
specifies terms and conditions of usage of
software.
57. Adoption of Open source in
India
• Kerala is the first state to start Free software
foundation in India.
• It introduced Free and Open source
software(FOSS) in education through IT@school
project.
• Foreign Countries
Germany,Malaysia, US,Brazil,France have started
migrating from proprietary softwares to open source
softwares
