2. Definition of web 2.0

• the term discribes a changed perception and

use of www

• main aspect: in internet user build or work on

contents itselfs

• examples: wikis, weblogs and picture –and

video-sharing-

portals

• Web 2.0: combination of different

technologies and a

commercial/promotional volitional

development trend

17

2. Definition of web 2.0

• technic approach: combination of developed

technics in the

end of 1990, which are large-area available

only new

• the term web 2.0 was descended by Dale

Dougherty and

Craig Cline

• first web-2.0-conference was in october 2004;

since then the

conforence takes place every year in october

3. History of Web 2.0• Web 0.5 = mainly used for e-mails and data communication• Web 1.0 = statical html, only one way communication and classic websites• Web 1.5 = Websites became more dynamic• Web 2.0 = principles of openness, standardisation and freedom

19

4. The Web As Platform• Web 2.0 doesn't have a hard boundary, but rather, a gravitational core• You can visualize Web 2.0 as a set of principles and practices that tie together a solar system of sites that demonstrate some or all of those principles:

20

4.1 Google

• Google is most certainly the standard bearer for Web 2.0• began its life as a native web application• was never sold or packaged• was delivered as a service• the customers of Google paying, directly or indirectly, for the use of that service• no licensing or sale, just usage

21

• no software releases, just continuous improvement• open source operating systems plus home grown applications and utilities • no one outside of the company ever gets to see these applications• Google happens in the space between browser and search engine and destination

4.1 Google

22

4.2 Web 2.0

Web 2.0 lesson: leverage customer-self service and algorithmic data management to reach out to the entire web, to the edges and not just the centre, to the long tail and not just the head

23

5. Collective Intelligence

• Hyperlinking is the foundation of the web

• users add new content, and new sites

• the web is bound in to the structure of the

web by other users

discovering the content and linking to it

• the web grows organically as an output of the

collective

activity of all web users

24

• Wikipedia

– an online encyclopedia based on the unlikely notion that an entry can be added by any web user, and edited by any other

– is a radical experiment in trust, applying

– Wikipedia is already in the top 100 websites of the world

25

6. Blogging

• Web 2.0 era is the rise of blogging• a blog is a user-generated website • mainstream media may see individual blogs as competitors• not a few people in a back room, decides what's important

26

7. End of the Software Release CycleNow Software has the characteristics of a service• Sequences of operations will be a core competency • Software will become quickly outdated• Use of dynamic script languages• The user must been seen as a co - developer• Use the open source idea • Real time monitoring for fast reaction• Two different business models as basic for software release

27

8. Lightweight Programming Models• allow for loosely coupled systems• think syndication, not coordination

– are about syndicating data outwards,– not controlling what happens when it gets to

the other end of the connection

28

• reflection of what is known as the end-to-end principle.

• systems like the original web, RSS, and AJAX all have this in common:– the barriers to re-use are extremely low,– software is actually open source,– "View Source" option to copy any other user's

web page

8. Lightweight Programming Models

29

9. Software Above the Level of a Single Device• No longer limited to PC platforms• Can be seen as device indipendent• Developed into synthetic web platform• Nothing completely new• To date, iTunes is the best exemplar of this principle• overchange from the handheld device to a massive web back-end • PC used as a local cache and control station• In this area greatest changes expected

30

10. Rich User Experiences• the key of rich user experiences is Ajax (Asynchronous JavaScript and XML)• used for example by Gmail or Google Maps• Web 2.0 enters an unprecedented period of user interface innovation• web developers are finally able to build web applications as rich as local PC-based applications

31

11. Practical example

• AJAX is a mixture of several technologies:– standards-based presentation using XHTML

and CSS; – 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

33

12. Core Competencies of Web 2.0 Companies

• Services, not packaged software, with cost-effective scalability

• Control over unique, hard-to-recreate data sources that get richer as more people use them

• Trusting users as co-developers • Harnessing collective intelligence

34

13. Review the Aspects of Web 2.0

Advantages: • Multi platform for PC, Mobile and so on• No huge degree of technical knowledge of

the user isneeded

• User oriented design• It is possible to update programmes over

the internet

35

Disadvantages: • is only a formal development of web 1.0

• the idea web 2.0 contains technologies

which are

different from aim of web 2.0

• web 2.0 could be also interpreted only as a

marketing

tool
