XML

XML is an initialism of Estensible Markup Language. This is a general purpose specification for creating personalized markup languages. It’s clasified as extensible language; it allows everyone to define the mark – up elements. XML a simple and a very flexible text format which derives from SGML and it was originally designed to to meet the challenges of large-scale electronic publishing. The objective is to help information systems in sharing and exchanging structured data, especially via the Internet, to encode documents, and to serialize data; in the last context, it compares serialization languages, which are based on texts, such as JSON and YAML.

Extensible Markup Language is highly recommended by the World Wide Web Consortium (W3C). It is a fee open standard. This recommendation tells us and specifies lexical grammar and parsing requirements.

To conclude, we can say that XML began as a simple subset of the SGML.
