XML

XML is a non-proprietary, text-based markup language that has become the standard for data interchange over the Internet and various distributed applications. It is a subset of Structured Generalized Markup Language (SGML), which is an international standard for describing the structure of different types of electronic documents.

Both XML and SGML are platform-independent and are used to create industry-specific markup languages. However, XML is easier to learn and implement than SGML.
