XML development

To address the requirements of commercial Web publishing and enable the further expansion of Web technology into new domains of distributed document processing, the World Wide Web Consortium (W3C) has developed an Extensible Markup Language (XML) for applications that require functionality beyond the current Hypertext Markup Language (HTML). XML is a universal language for data on the Web that lets developers deliver content from a wide variety of applications to the desktop. XML promises to standardize the way information is searched for, exchanged, adaptively presented, and personalized.
Data such as customer information, credit card transactions, purchase orders, and fulfillment requests can be converted to XML and shared across applications without changing legacy systems. XML can be used to exchange data between Web server and browser or between trading partners without the existing systems needing any prior description of the data’s structure.
The applications that drive the acceptance of XML are those that cannot be accomplished within the limitations of HTML.
These applications can be divided into three broad categories:
Applications that require the Web client to mediate between two or more heterogeneous databases.
Applications that attempt to distribute a significant proportion of the processing load from the Web server to the Web client.
Applications that require the Web client to present different views of the same data to different users.
We focus on the following XML Applications Areas:
Use of XML for data transfer
Use of XML for data transfer
Use of XML for data distribution
For publication of data
For offline/online data synchronization
Enable internationalized media-independent electronic publishing
Allow industries to define platform-independent protocols for the exchange of data, especially the data of electronic commerce
Deliver information to user agents in a form that allows automatic processing after receipt
Make it easier to develop software to handle specialized information distributed over the Web
Make it easy for people to process data using inexpensive software
Allow people to display information the way they want it, under style sheet control
Make it easier to provide metadata — data about information — that will help people find information and help information producers and consumers find each other.
