16. 16 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. 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

18. 18 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. 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. 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. 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. 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. 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. 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. 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. 26 7. End of the Software Release Cycle Now 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. 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. 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. 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. 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. 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. 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. 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 is needed User oriented design It is possible to update programmes over the internet

35. 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 13. Review the Aspects of Web 2.0
