XML or extensible mark-up language is extensively used when it comes to the Web. What is XML? How did it come into being and why is it the buzzword in the online platform?

Starting from mark-up languages, HTML made a mark in presenting well-structured web documents. While the visual aspects of a web-page were taken of, storage of data and transportation of data posed an issue, with repeated references made to the server. The repeated requests to the back-end considerably reduced the download speed and increased the load on the server as well. XML evolved with the purpose of intermediate storing of data and transportation. In the current context, XML has given way to build robust, secure web architectures. Let us see how.

The data stored in XML file can be imported from any client service (web-reports, ms office tools, etc), and displayed in the desired format. This explains why XML has become the viable interface or the standard for interchange of data across applications. The XML files are interoperable across different devices as well. For instance, a data-store file generated by a PC using XML can be downloaded or preserved in the same format in a mobile or smart-phone. As electronic data interchange (EDI) is the cornerstone of ecommerce applications; web portals where data spread across different applications need to be consolidated under one standard format, make the best use of XML files.

Another vital use of XML, which pulsates in the web-context, is the rendering of interactive WebPages in combination with JavaScript, also known as AJAX. This technology has overridden the erstwhile limitations associated with page loading, bandwidth, generating seamless connectivity through AJAX-enabled user interface.

Moving from user-interface to high visibility in search engines, XML data files are instinctively search-engine optimized as they clearly define the content that is in store. The structured approach of XML files-definition with appropriate user-defined tags makes it easy for the search-engine algorithms to crawl up the page and understand the key content of the site. Thus the visibility of a site and its ranking with search engines increases with the effective usage of XML files. The visibility of a site can further be promoted using metadata applications. As the web platform grows to a limitless expanse, it becomes imperative to have “data about the data”. Inline, metadata applications come into play to provide vital information about the website. XML steps in as the portable and platform-friendly channel to transfer metadata and display in a reusable portable format.

As seamless connectivity lays down the importance of wireless connectivity and wireless devices, XML comes out with portable and structured information types for Personal digital assistants (PDAs) to display the data according to the interface.
