3 Web 2.03 A Quick History of the Internet  Late 60s : first TCP/IP Network  Decentralized - to survive nuclear holocaust  70s-80s : Utilized for research, academia  Early communities : e-lists, USENET  Late 80s : Web invented  Early 90s : Networks privatized  1995 : AOL opens Web gateway …and the rest is history….

4 Web 2.04 The Internet Goes to School  Late 80s : First schools gain Net access  1994 : Just 4% of classrooms online  NetDay ’96 : Volunteers wire schools  E-Rate : Federal subsidies for Internet access  Today : Nearly 100% of schools online, 90%+ of classrooms, 70%+ of students at home

14 14 Web 2.0  The more explicit synonym "Participatory Web", emphasizing tools and platforms that enable the user to:  tag,  blog,  comment,  modify,  augment,  select from,  rank, and  generally talk back to the contributions of other users and the general world community

15 Web 2.015 Web 2.0  What was it that made us identify one application or approach as "Web 1.0" and another as "Web 2.0"? You can visualize Web 2.0 as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core.You can visualize Web 2.0 as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core.

18 18 Web 2.0 Membership at social networking sites such as Facebook and MySpace is exploding. In June, 2 out of every 3 people online visited a social networking site. Since January 2004, the number of people visiting or taking part in one of the top online social networks has grown by over 109% (primarily driven by MySpace). Social networking sites are now close to eclipsing traffic to the giants - Google and Yahoo.

19 Web 2.019 Web 2.0  The bursting of the dot-com bubble in the fall of 2001 marked a turning point for the web  2004 - The concept of "Web 2.0" began with a conference brainstorming session between O'Reilly and MediaLive International  Some commentators regard reputation-based public wikis, such as Wikipedia, as pioneering examples of Web 2.0/Participatory Web technology.

20 Web 2.020 Web 2.0  The phrase Web 2.0 in 2004 to refer to a supposed second-generation of Internet-based services that let people collaborate (participatory) and share information online in perceived new ways — such as:- social networking sites,social networking sites, wikis,wikis, communication tools,communication tools, folksonomiesfolksonomies

24 Web 2.024 Web 2.0  Netscape vs. Google  In the end, both web browsers and web servers turned out to be commodities, and value moved "up the stack" to services delivered over the web platform.  At bottom, Google - database management.  Google isn't just a collection of software tools, it's a specialized database.

25 Web 2.025 Web 2.0  The 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 center, to the long tail and not just the head.

26 Web 2.026 Web 2.0  Other web 2.0 success stories demonstrate this same behavior.  eBay enables occasional transactions of only a few dollars between single individuals, acting as an automated intermediary.  Napster (though shut down for legal reasons) built its network not by building a centralized song database, but by architecting a system in such a way that every downloader also became a server, and thus grew the network.

27 Web 2.027 Web 2.0  2. Harnessing Collective Intelligence  Akamai vs. BitTorrent Akamai is optimized to do business with the head/center (big servers), not the tail/edges (PC).Akamai is optimized to do business with the head/center (big servers), not the tail/edges (PC). While it serves the benefit of the individuals at the edge of the web by smoothing their access to the high-demand sites at the center, it collects its revenue from those central sites.While it serves the benefit of the individuals at the edge of the web by smoothing their access to the high-demand sites at the center, it collects its revenue from those central sites.

30 Web 2.030 Web 2.0  The central principle behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era appears to be this, that they have embraced the power of the web to harness collective intelligence :that they have embraced the power of the web to harness collective intelligence :  Yahoo!, Web 1.0 success story, was born as a catalog/directoryof links, an aggregation of the best work of thousands, then millions of web users.  Yahoo! Web 2.0 - business of creating many types of content, a portal to the collective work of the net's users remains the core of its value.

33 Web 2.033 Web 2.0  Now, innovative companies that pick up on this insight and perhaps extend it even further, are making their mark on the web:  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,  This is a profound change in the dynamics of content creation ! – Information is transitional

34 Web 2.034 Web 2.0  Sites like del.icio.us and Flickr, two companies that have received a great deal of attention of late, have pioneered a concept that some people call - folksonomy Classifying Web sites by the user community rather than by taxonomy professionals.Classifying Web sites by the user community rather than by taxonomy professionals. provide a democratic tagging system that reflects the opinions of the general publicprovide a democratic tagging system that reflects the opinions of the general public a style of collaborative categorization of sites using freely chosen keywords – Bully, Malaysia, students, often referred to as tags.a style of collaborative categorization of sites using freely chosen keywords – Bully, Malaysia, students, often referred to as tags.  a taxonomy (controlled vocabulary ) in that the authors of the labeling system are often the main users (and sometimes originators) of the content to which the labels are applied.

Instant fav, love the colours.

39 Web 2.039 Web 2.0  Folksonomy- a style of collaborative categorization of sites using freely chosen keywords, often referred to as tags.  Tagging allows for the kind of multiple, overlapping associations that the brain itself uses, rather than rigid categories.  In the canonical example, a Flickr photo of a puppy might be tagged both "puppy" and "cute"--allowing for retrieval along natural axes generated user activity

40 Web 2.040 Web 2.0  What are tags? You can give your photos a "tag", which is like a keyword.  Tags help you find photos which have something in common.  You can assign as many tags as you wish to each photo.

42 Web 2.042 Web 2.0  Blogging and the Wisdom of Crowds  A weblog, which is usually shortened to blog, is a type of website where entries are made (such as in a journal or diary), displayed in a reverse chronological order.  Blogs often provide commentary or news and information on a particular subject, such as food, politics, or local news; some function as more personal online diaries.

43 Web 2.043 Web 2.0  A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic.  Most blogs are primarily textual although some focus on:- photographs (photoblog),photographs (photoblog), videos (vlog),videos (vlog), audio (podcasting).-audio (podcasting).-

62 62 Web 2.0  Personal home pages, personal diary and daily opinion column have been around since the early days of the web  One of the things that has made a difference is a technology called RSS.  RSS allows someone to link not just to a page, but to subscribe to it, with notification every time that page changes.

63 Web 2.063 Web 2.0  File extension:.rss,.xml  MIME type :application/rss+xml  Type of format:Syndication  Extended from:XML  Skrenta calls this "the incremental web." Others call it the "live web". Today: 60-100 million+ blogs onlineToday: 60-100 million+ blogs online

64 Web 2.064 Web 2.0  On Web pages, web feeds (RSS or Atom) are typically linked with the word "Subscribe", an orange rectangleor with the letters or.  Many news aggregators such as My Yahoo! publish subscription buttons for use on Web pages to simplify the process of adding news feeds

70 70 Web 2.0  RSS is a type of web feed.  RSS delivers its information as an XML file called an "RSS feed", "webfeed", "RSS stream", or "RSS channel".  These RSS feeds provide a way for users to passively receive newly released content (such as text, web pages, sound files, or other media); this might be the full content itself or just a link to it, possibly with a summary or other metadata (data describing the content).

71 Web 2.071 Web 2.0  RSS is now being used to push not just notices of new blog entries, but also all kinds of data updates, including stock quotes, weather data, and photo availability.  RSS was born in 1997 out of the confluence of Dave Winer's "Really Simple Syndication" technology, used to push out blog updates.

72 Web 2.072 Web 2.0  An RSS feed is thus a much stronger link than, say a bookmark or a link to a single page  RSS also means that the web browser (My Yahoo!) is not the only means of viewing a web page.  While some RSS aggregators, such as :  Bloglines, are web-based,  others are desktop clients,  Yahoo! Mobile - portable devices allows to subscribe to constantly updated content.

73 Web 2.073 Web 2.0  The syndicated content an aggregator will retrieve and interpret is usually supplied in the form of RSS or other XML-formatted data  http://www.newsonfeeds.com/faq/aggregators http://www.newsonfeeds.com/faq/aggregators

74 Web 2.074 Web 2.0

75 75 Web 2.0  Dynamic websites (i.e., database-backed sites with dynamically generated content) replaced static web pages well over ten years ago.  What's dynamic about the live web are not just the pages, but the links.  A link to a weblog is expected to point to a perennially changing page, with "permalinks" for any individual entry, and notification for each change.

76 Web 2.076 Web 2.0  Tom Coates remarks on the significance of the permalink:  It may seem like a trivial piece of functionality now, but it was effectively the device that turned weblogs from an ease-of-publishing phenomenon into a conversational mess of overlapping communities.  For the first time it became relatively easy to gesture directly at a highly specific post on someone else's site and talk about it.  Discussion emerged. Chat emerged. And - as a result - friendships emerged or became more entrenched.

77 Web 2.077 Web 2.0  The permalink was the first - and most successful - attempt to build bridges between weblogs.  Permalink example.png - #

78 Web 2.078 Web 2.0  Permalink example.png - #  permanent URLs to your individual weblog posts, as well as categories and other lists of weblog postings.  is what another weblogger will use to refer to your article (or section), or how you might send a link to your story in an e-mail message  once a story is posted, the URL to it should be permanent, and never change. Hence the "perma" in the name..

79 Web 2.079 Web 2.0  Permalink is made by contracting the phrase "permanent link".  A permalink is a term used in the world of blogging to indicate a URL which points to a specific blog entry.  A permalink is accessible even after the entry has passed from the front page and into the blog archives.

80 Web 2.080 Web 2.0

81 81 Web 2.0  The permanent URLs created are often simple and human- readable to ease the process of linking to a particular entry and are designed within blogging software to remain unchanged indefinitely so as to help prevent link rot.  The practice is utilized by mainstream news and other types of websites as well, although the term permalink is most common within the blogosphere.  Permalinks are supported in most modern weblogging and content syndication software systems, including Movable Type, LiveJournal, and Blogger

82 Web 2.082 Web 2.0  Not only can people subscribe to each others' sites, and easily link to individual comments on a page, but also, via a mechanism known as trackbacks, they can see when anyone else links to their pages, and can respond, either with reciprocal links, or by adding comments  http://en.wikipedia.org/wiki/Web_2.0 http://en.wikipedia.org/wiki/Web_2.0

83 Web 2.083 Web 2.0

84 84 Web 2.0  3. Data is the Next Intel Inside  Every significant internet application to date has been backed by a specialized database:  Google's web crawl,  Yahoo!'s directory (and web crawl),  Amazon's database of products,  eBay's database of products and sellers,  MapQuest's map databases,  Napster's distributed song database.  Database management is a core competency of Web 2.0 companies.

85 Web 2.085 Web 2.0  This fact leads to a key question:  Who owns the data? In the internet era, one can already see a number of cases where control over the database has led to market control and outsized financial returns.In the internet era, one can already see a number of cases where control over the database has led to market control and outsized financial returns. The monopoly on domain name registry initially granted by government fiat to Network Solutions (later purchased by Verisign) was one of the first great moneymakers of the internet.The monopoly on domain name registry initially granted by government fiat to Network Solutions (later purchased by Verisign) was one of the first great moneymakers of the internet. www.durian.com.mywww.durian.com.mywww.durian.com.my

Maps andYahoo! Maps and MapQuest.MapQuest. Its main rival is the Dutch company Tele Atlas.Its main rival is the Dutch company Tele Atlas.

87 Web 2.087 Web 2.0  The now hotly contested web mapping arena demonstrates how a failure to understand the importance of owning an application's core data will eventually undercut its competitive position.  MapQuest pioneered the web mapping category  1995, yet when Yahoo!, and then Microsoft, and most recently Google, decided to enter the market, they were easily able to offer a competing application simply by licensing the same data.

88 Web 2.088 Web 2.0  The recent introduction of Google Maps provides a living laboratory for the competition between application vendors and their data suppliers.  Google's lightweight programming model has led to the creation of numerous value-added services in the form of mashups that link Google Maps with other internet-accessible data sources.  Paul Rademacher's housingmaps.com, which combines Google Maps with Craigslist apartment rental and home purchase data to create an interactive housing search tool, is the pre-eminent example of such a mashup. housingmaps.comCraigslisthousingmaps.comCraigslist

89 Web 2.089 Web 2.0  A mashup is a website or Web 2.0 application that uses content from more than one source to create a completely new service.  This is akin to transclusion - In computer science, is the inclusion of part of a document into another document by reference  Content used in mashups is typically sourced from a third party via a public interface or API.

90 Web 2.090 Web 2.0  Other methods of sourcing content for mashups include Web feeds (e.g. RSS or Atom) and JavaScript.  An example is Diggdot.us, combines feeds from the techie-oriented news sources Digg.com,Digg.com, Slashdot.org, andSlashdot.org, and Del.icio.us, reddig.com.Del.icio.us, reddig.com.

91 Web 2.091 Web 2.0  Digg.com  What is Digg?  User driven social content website.  Everything on digg is submitted by the digg user community (that would be you).  Other digg users read your submission and digg what they like best.  If your story rocks and receives enough diggs, it is promoted to the front page for the millions of digg visitors to see.

92 Web 2.092 Web 2.0  What can you do as a digg user?  Every digg user can digg (help promote), bury (help remove spam), and comment on stories... you can even digg and bury comments you like or dislike.  Digg also allows you to track your friends' activity throughout the site — want to share a video or news story with a friend?  Digg it!

95 95 Web 2.0  4. End of the Software Release Cycle  The main characteristics of Internet era software is that it is delivered as a service, not as a product.  This fact leads to a number of fundamental changes in the business model of such a company:  Operations must become a core competency.

96 Web 2.096 Web 2.0  Google's or Yahoo!'s expertise in product development must be matched by an expertise in daily operations.  So fundamental is the shift from software as artifact to software as service that the software will cease to perform unless it is maintained on a daily basis.

97 Web 2.097 Web 2.0  Google must continuously: crawl the web and update its indices,crawl the web and update its indices, filter out link spam and other attempts to influence its results,filter out link spam and other attempts to influence its results, and dynamically respond to hundreds of millions of asynchronous user queries, simultaneously matching them with context-appropriate advertisements.and dynamically respond to hundreds of millions of asynchronous user queries, simultaneously matching them with context-appropriate advertisements.

100 Web 2.0100 Web 2.0  Users must be treated as co-developers,  Software - "release early and release often" in fact has morphed into an even more radical position, "the perpetual beta," in which the product is developed in the open, with new features slip streamed in on a monthly, weekly, or even daily basis.  It's no accident that services such as Gmail, Google Maps, Flickr, del.icio.us, and the like may be expected to bear a "Beta" logo for years at a time.

101 Web 2.0101 Web 2.0  Real time monitoring of user behavior to see just which new features are used, and how they are used, thus becomes another required core competency.  A web developer at a major online service remarked: "We put up two or three new features on some part of the site every day, and if users don't adopt them, we take them down.  If they like them, we roll them out to the entire site."

102 Web 2.0102 Web 2.0  ZDnet editorial concluded that Microsoft won't be able to beat Google: "Microsoft's business model depends on everyone upgrading their computing environment every two to three years."Microsoft's business model depends on everyone upgrading their computing environment every two to three years. Google's depends on everyone exploring what's new in their computing environment every day."Google's depends on everyone exploring what's new in their computing environment every day."
