Extensible Markup Language (XML) is a simple, flexible text format developed by the World Wide Web Consortium (W3C) to enable structured data exchange across systems, originally for large-scale publishing but now widely used for data interoperability on the web. It serves as a foundational technology within the W3C's web architecture stack, designed to be both human-readable and machine-processable. Key components include XML 1.0 and XML 1.1, which define syntax and parsing rules; Namespaces in XML, used to avoid element name conflicts; XML Schema (XSD), for defining and validating document structure; XML Information Set (Infoset), which abstracts XML data into a standard model; and XInclude, enabling modular document assembly. These specifications support robust, standardized data representation across diverse applications. This technology is for developers, data architects, and technical authors who need to design, validate, or exchange structured information across platforms, particularly in publishing, enterprise integration, and web services, where reliable, self-describing data formats are essential.
