   What is Web 2.0?
        Web 2.0 is a trend in World Wide Web technology, and web design, a second
         generation of web-based communities and hosted services such as social-
         networking sites, wikis, blogs, and folksonomies, which aim to facilitate creativity,
         information sharing, collaboration, and sharing among users. It is almost defined as
         the new era of the World Wide Web. The term became notable after the first O'Reilly
         Media Web 2.0 conference in 2004.[2][3] Although the term suggests a new version
         of the World Wide Web, it does not refer to an update to any technical specifications,
         but to changes in the ways software developers and end-users use webs. According
         to Tim O'Reilly:
        “Web 2.0 is the business revolution in the computer industry caused by the move to
         the Internet as platform, and an attempt to understand the rules for success on that
         new platform.[4]”Some technology experts, notably Tim Berners-Lee, have
         questioned whether one can use the term in a meaningful way, since many of the
         technology components of "Web 2.0" have existed since the early days of the
         Web.[5][6] (Source: Wikipedia)
Web 2.0 Definition
   Tim O'Reilly regards Web 2.0 as business embracing the web as a
    platform and using its strengths (global audiences, for example).
   Eric Schmidt's abridged slogan, don't fight the Internet, encompasses
    the essence of Web 2.0 — building applications and services around
    the unique features of the Internet
   Web 2.0" can also relate to a transition of some websites from isolated
    information silos to interlinked computing platforms that function
    like locally-available software in the perception of the user
   includes a social element where users generate and distribute content,
    often with freedom to share and re-use
   rise in the economic value of the web to businesses, as users can
    perform more activities online
   Change the nature of the Web from distributed to participatory
   Not a technological revolution it’s a social revolution

Open Source
   Genesis of Web 2.0
   Proponents believe the source code for programs should
    be available to anyone to use, study, enhance and
   Open source is a set of principles and practices on how to
    write software, the most important of which is that the
    source code is openly available. The Open Source
    Definition, which was created by Bruce Perens[1] and Eric
    Raymond and is currently maintained by the Open Source
    Initiative, adds additional meaning to the term: one should
    not only get the source code but also have the right to use
    it. If the latter is denied the license is categorized as a
    shared source license. (Source: Wikipedia)
Open Source Definition
Under The Open Source Definition, licenses must meet ten conditions in order to be considered open
source licenses. Below is a copy of the definition, with unauthorized explanatory additions. There is a link
to the original unmodified text below. It was taken under/for fair use.

1.    Free Redistribution: the software can be freely given away or sold. (This was intended to encourage
      sharing and use of the software on a legal basis.)
2.    Source Code: the source code must either be included or freely obtainable. (Without source code,
      making changes or modifications can be impossible.)
3.    Derived Works: redistribution of modifications must be allowed. (To allow legal sharing and to permit
      new features or repairs.)
4.    Integrity of The Author's Source Code: licenses may require that modifications are redistributed only
      as patches.
5.    No Discrimination Against Persons or Groups: no one can be locked out.
6.    No Discrimination Against Fields of Endeavor: commercial users cannot be excluded.
7.    Distribution of License: The rights attached to the program must apply to all to whom the program is
      redistributed without the need for execution of an additional license by those parties.
8.    License Must Not Be Specific to a Product: the program cannot be licensed only as part of a larger
9.    License Must Not Restrict Other Software: the license cannot insist that any other software it is
      distributed with must also be open source.
10.   License Must Be Technology-Neutral: no click-wrap licenses or other medium-specific ways of
      accepting the license must be required. (Source: Wikipedia)
   Metadata
   Traditional Web Pages
       Search engines can find content because of content
        managers adding metadata or metatags
   Web 2.0
       Organized differently
       It uses words that authors select and attach to content
        called folksonomies
            Keywords or tags that convey meaning to content
            Tags are logical and can be arranged in groups into concept
             maps called tag clouds

   Making information available to other web
    sites or to individual subscribers
       Done by adding XML code that readers can use
   RSS
     Really Simple Syndication
     Difference between going out to find something
      or having it come to you

   Using an aggregator
       Don’t have to keep checking for updates
       RSS feeds
   In computing, a feed aggregator, also known as a
    feed reader, news reader or simply as an
    aggregator, is client software or a Web
    application which aggregates syndicated web
    content such as news headlines, blogs, podcasts,
    and vlogs in a single location for easy viewing.
