XML metadata was conceptualized and developed specifically to support markup language technologies. Simply said, XML metadata is designed primarily to simplify web context. Whether a web page contains text, graphics, audio, or video, XML metadata will be able to simplify the language of web content so that different applications can read the data and display it on the interface in recognizable format.
Metadata means data within data. So, it is a set of information that contained the specifics or the detailed description of the information itself. Through metadata, a markup or web content can be easily understood. With the development of Extensible Markup Language or XML, the delivery of metadata goes a step further. Through this technology, data contained on a web page or any other media channels, can be displayed correctly.
XML metadata can be used in many ways. The most extensive use of this technology however can be seen on web development and media applications using HTML as a delivery medium. Users therefore can understand the context of data, display pages and receive media content on any format or platform. This makes the delivery of information more flexible and extremely user-friendly.
XML metadata is also commonly used for web optimization purposes. As search engine algorithms became more sophisticated in contextualizing the content of a website, the importance of providing metadata information also became more important. XML metadata will be used by the developer to describe the entire content of a webpage to make it friendlier to search engines.
