XML

Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable.

Description

The design goals of XML emphasize simplicity, generality and usability across the Internet.

It is a textual data format with strong support via Unicode for different human languages.

Web services

Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures such as those used in web services.

Schema systems

Several schema systems exist to aid in the definition of XML-based languages, while many application programming interfaces (APIs) have been developed to aid the processing of XML data.

Definition

It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards.
