XML
The Extensible Markup Language (XML) is a format for structured documents and data. It was developed by the World Wide Web Consortium (W3C). XML is a meta-language, i.e. content is not directly encoded in XML but in a specific markup language defined using XML It corresponds to the successor language for the current HTML. In contrast to HTML where tags are pre- defined, the XML user can freely extend a data format applying his or her own uniquely defined tags. Since the tag structure in the case of XML enables the computer to automatically analyse data content, building EC (electronic commerce) and ED (electronic data interchange) systems is facilitated.
