This document provides an overview of the Web 2.0 standard, including its key characteristics and technologies. It compares Web 1.0 and 2.0, outlines different levels of Web 2.0 integration for applications and products, and describes technologies like tagging, wikis, APIs, and Ajax that power interactive and collaborative Web 2.0 experiences. The goal of Web 2.0 is to create a more user-focused web that facilitates participation, openness, and collective intelligence through these technologies.
53. Web Platform Web 2.0 Applications XML, API, WS Web Platform Core Framework
54. Characteristics “The basic of … relinquishing control” The point isn't the features, it's the underlying philosophy of relinquishing control.
55. Characteristics “Glocalization …” Glocalizationis a portmanteau word of globalization and localization. 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
63. Characteristics “Crowd-sourcing” Every small unit of contribution is important to a Web 2.0 service. Millions of such contributions eventually lead the website to state of higher relevance
75. Technology and Component Overview “Tags…” Categorization of content by creating tags that are simple, one-word descriptions to facilitate searching and avoid rigid, pre-made categories.
82. Technology and Component Overview “Wiki…” Wikis are generally designed with the philosophy of making it easy to correct mistakes, rather than making it difficult to make them
86. Technology and Component Overview “Signals…” The use of RSS (Really Simple Syndication) technology to notify users with any changes of the content by sending e-mails to them.
87. Technology and Component Overview “Ajax…” With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page. The use of Ajax has led to an increase in interactive animation on web pages
88. Technology and Component Overview “Open API…” Machine-based interaction, a common feature of Web 2.0 sites, uses two main approaches to Web APIs, which allow web-based access to data and functions REST and SOAP
90. ImproveYourAnalyticCapability Simplicity”Other things should be equal simpler theories are better“ Logicality”The basis of rationality and a foundation for mathematics, science and technology“ User Friendly ”Make it easy for using the technology themselves“ Reality
91. Why Web 2.0? Web as platform Harnessing collective intelligence Data is the next Intel Inside End of the software release cycle Lightweight programming models
