It was the first separate schema language for XML to achieve Recommendation status by the W3C. Because of confusion between XML Schema as a specific W3C specification, and the use of the same term to describe schema languages in general, some parts of the user community referred to this language as WXS, an initialism for W3C XML Schema, while ...
MARCXML - a direct mapping of the MARC standard to XML syntax; METS - a schema for aggregating in a single XML file descriptive, administrative, and structural metadata about a digital object; MODS - a schema for a bibliographic element set and maintained by the Network Development and MARC Standards Office of the Library of Congress [6]
Unlike W3C XML Schema, RELAX NG was designed so that validation and augmentation (adding type information and default values) are separate. W3C XML Schema has a formal mechanism for attaching a schema to an XML document, while RELAX NG intentionally avoids such mechanisms for security and interoperability reasons.
An XML Schema Definition is itself an XML document while a DTD is not. RELAX NG, which is also a part of DSDL, is an ISO international standard. [9] It is more expressive than XSD, [citation needed] while providing a simpler syntax, [citation needed] but commercial software support has been slow in coming.
XSL (Extensible Stylesheet Language) is a family of languages used to transform and render XML documents, split into three parts: XSLT (XSL Transformations), an XML language for transforming XML documents into other XML documents or other formats such as HTML, plain text, or XSL-FO. XSLT is very tightly coupled with XPath, which it uses to ...
The W3C's XML Schema Recommendation defines a formal mechanism for describing XML documents. The standard has become popular and is used by the majority of standards bodies when describing their data. [1] The standard is versatile, allowing for programming concepts such as inheritance and type creation, but it is complex.
ODD: A 'One Document Does-it-all' TEI format for simultaneously recording project documentation and meta-schema definition from which you can generate RELAX NG, W3C XML Schema, and DTDs as well as formatted documentation. ODRL: an XML-based standard Rights Expression Language (REL) used in digital rights management systems
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, [ 1 ] and can be used to compute values (e.g., strings , numbers, or Boolean values ) from the content of an XML document.
