The term metadata is generally interpreted as "Data about data" or "Data about applications." In the enterprise application space, the definition has been expanded to encompass various kinds of standardized languages, such as XXII. Schema Definition (XSD), Web Service Definition Language (WSDL) Java Server Faces (JSF) pages, and custom and proprietary languages. More importantly, metadata is increasingly used to represent and affect application logic, resulting in applications that are metadata driven as opposed to code driven.
