  • 11. DEFINITIONS
    • The web as platform.
    • The underlying philosophy of relinquishing control.
    • Glocalization -- making global information available to local social contexts and giving people the flexibility to find, organize, share and create information in a locally meaningful fashion that is globally accessible.
    • An attitude not a technology – Participatory.
    • When data, interface and metadata no longer need to go hand in hand.
    • Power and control via APIs.
    • Giving up control and setting the data free.
  • 12. PEOPLE HAVE HEARD OF
    • Blogs, e.g. Blogger, Blogspot
    • Del.icio.us
    • Wikis, e.g. Wikipedia
    • Flickr for photo sharing

    • Links - To frequently used pieces of information.
    • Authoring - Create constantly updating content which is cumulative such as in blogs and as in wikis it is iterative.
    • Tags - Categorization of content by simple, one-word descriptions to facilitate searching and avoid rigid, pre-made categories.

    • User interface functionality of desktop software applications.
    • Low-cost deployment of Web applications.
    • Interactive, multimedia communication.
    • Responsive, and effective user experience.
  • 16. SERVICE ORIENTED ARCHITECTURE
    • Application's business logic or individual functions are modularized and presented as services for consumer/client applications.
    • loosely coupled nature; i.e., the service interface is independent of the implementation.
    • Application developers or system integrators can build applications by composing one or more services without knowing the services' underlying implementations.

  • 20. FEEDS
    • Web feed (or news feed) is a data format used for providing users with frequently updated content.
    • Web feeds are an example of pull technology, although they may appear to push content to the user.
    • Content distributors syndicate(make publicly available) a web feed, thereby allowing users to subscribe to it.
    • Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by an Internet aggregator.
    • Sometimes third parties will read the website and create a feed for it by scraping it.
    • RSS (most commonly said to be an acronym for ‘Really Simple Syndication’) format is an XML-based system that allows users to subscribe to their favorite websites.
  • 21.  
  • 22. AJAX
    • AJAX is a group of technologies
    • XHTML and CSS give standards based presentation
    • Dynamic display and interaction using the DOM
    • Data interchange and manipulation using XML and XSLT
    • Asynchronous data retrieval using XMLHttpRequest and Javascript binding it all together.
    • Web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.
