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.

PEOPLE HAVE HEARD OF

Blogs, e.g. Blogger, Blogspot Del.icio.us Wikis, e.g. Wikipedia Flickr for photo sharing Communication networks, e.g. Skype News & audio services, like podcasts &

Youtube Social networking sites, e.g. Myspace &

Facebook

KEY FEATURES

Search - Finding information through keyword. 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.

Signals - The use of RSS (Really Simple Syndication) technology to notify users with any changes of the content by sending e-mails to them.

COMPONENTS

RIA – Rich Internet Application SOA – Service Oriented Architecture SW – Social Web

RIA – RICH INTERNET APPLICATIONS

Combination of : User interface

functionality of desktop software applications.

Low-cost deployment of Web applications.

Interactive, multimedia communication.

Responsive, and effective user experience.

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.

SOCIAL WEB

Multimedia – Photo-sharing: Flickr – Video-sharing: YouTube – Audio-sharing: imeemEntertainment – Virtual Worlds: Second Life – Online Gaming: World of

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.

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.
