Chapter 11. XML and Web Services > Basic XML Standards and Technologies

Basic XML Standards and Technologies

Much of the ongoing development and standardization of XML technologies is proceeding under the auspices of the W3C. The W3C is concentrating on basic XML technologies and on XML for presentation and is mostly leaving XML for data exchange and communications up to other groups. The W3C effort in XML is managed by the W3C Architecture Domain and is divided into several working groups.

  • The XML Core Working Group is responsible for the core syntax of XML and such auxiliary areas as the XInclude recommendation.

  • The XML Schema Working Group is broadly responsible for data types and structural constraints in XML, including the XSchema recommendation.

  • The XML Linking Working Group is responsible for XML variants of hypertext links, particularly for the XLink and XPointer recommendations.

  • The XML Query Working Group is broadly responsible for information retrieval from XML data sources and specifically for the XQuery recommendation.

  • The XSL Working Group is under the aegis of the W3C Document Formats Domain rather than the Architecture Domain. It is responsible for the XSLT transformation language, the XPath expression language, and XSL Formatting Objects, a particular XML vocabulary for formatting documents for display.
