Inventor of the Web, Sir Tim Berners-Lee was asked whether Web 2.0 was different to what might be called Web 1.0
"Totally not. Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0 is of course a piece of jargon, nobody even knows what it means. If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along. And in fact, you know, this 'Web 2.0', it means using the standards which have been produced by all these people working on
Web 1.0.

What is Web 2.0: Design Patterns and Business
Models for the Next Generation of Software

•
Describes seven principles:
•
The Web as platform, Harnessing collective intelligence, Data is the next 'Intel inside', End of the software release cycle, Lightweight programming models, Software above the level of single device, and Rich user experiences.

•
Web 2.0 encompasses a variety of different meanings that include an increased emphasis on user generated content, data and content sharing and collaborative effort
•
It is also together with the use of various kinds of social software, new ways of interacting with webbased applications, and the use of the web as a platform for generating, re-purposing and consuming content.

• Participation
• Standards
• Decentralization
• Openness
• Modularity
• User Control
• Identity
7

• Every aspect of Web 2.0 is driven by participation.
• The transition to Web 2.0 was enabled by the emergence of platforms such as blogging, social networks, and free image and video uploading
• These allowed extremely easy content creation and sharing by anyone.
8

• Standards provide an essential platform for
Web 2.0
• Common interfaces for accessing content and applications are the glue that allow integration across the many elements of the emergent web
9

• Web 2.0 is decentralized in its architecture, participation, and usage
• Power and flexibility emerges from distributing applications and content over many computers and systems, rather than maintaining them on centralized systems
10

• The world of Web 2.0 has only become possible through a spirit of openness whereby developers and companies provide open, transparent access to their applications and content
11

• Web 2.0 emerges from many
• Many components or modules that are designed to link and integrate with others, together building a whole
12

• A primary direction of Web 2.0 is for users to control the
• content they create
• data captured about their web activities, and
• their identity
13

• Identity is a critical element of both Web 2.0
and the future direction of the internet
• We can choose to represent our identities across interactions, virtual worlds, and social networks.
• We can also own and verify our real identities in transactions
14

• Blogs
• Wikis
• Content Tagging
• Multimedia Sharing
• Content Syndication (RSS)
• Audio Blogging and Podcasting
• Latest Web 2.0 services & applications

“A simple webpage consisting of brief paragraph of opinion, information, personal diary entries, links
(posts), arranged chronologically with the most recent first, in the style of an online journal.”

• The term "weblog" was coined by Jorn Barger on 17
December 1997.
• The short form, "blog," was coined by Peter Merholz, who jokingly broke the word WEBLOG into the phrase
WE BLOG in the sidebar of his blog Peterme.com in
April or May of 1999.
• This was quickly adopted as both a noun and verb
("to blog," meaning "to edit one's weblog or to post to one's weblog")

41

42

• Ownership
• Re-use
• Control
43

Who "owns" the content when it is collaboratively created? The authors? The university? The creators of the system?
44

• Universities make considerable use of published materials in learning and teaching. These materials may be in paper or electronic form. They include text books, academic papers, learning objects and preprints.
• When these are used in a Web 2.0 environment they may become visible to people outside the university, which may breach current licensing arrangements, so that they may need to be reconsidered.
45

• The nature and degree of control that universities may wish to exert over content in a Web 2.0 environment is, as discussed, problematic because there are competing pressures to ensure that material is not illegal
(eg defamatory or contravening IPR), and to support academic freedom
46

• One of the key functions of universities has been the preservation of information.
• Historically this has been done using published works and theses retained in a library.
47

• What is the authoritative version of an artifact? This is especially problematic where many people are contributing to it.
• At what point does it become something that should be preserved?
• Should all the changes be preserved too?
48

• What is the status of a work?
• If it can always be changed then how can peer review (or similar processes) be used to determine the work’s value and authority?
• How does preservation relate to the version(s) that were peer reviewed?
• And what is the scope of any such peer review?
49

• How can the content be preserved in a form in which it can continue to be accessed?
• Technology is changing very fast, and while some formats will be usable for a long time (HTML for instance)
• Others may not be. Will a MySQL database still be usable in 20 years on the hardware and operating systems available then?
50

• Web 2.0 will have profound implications for librarians, learners and teachers in formal, informal, work-based and lifelong education.
• Web 2.0 will affect how library and universities go about the business of education, from learning, teaching and assessment, through contact with school communities, widening participation, interfacing with industry, and maintaining contact with alumni
