XML-based standards

WDDX (Web Distributed Data eXchange) is a programming language-, platform- and transport-neutral data interchange mechanism designed to pass data between different environments and different computers.

Object Management Group standard

Windows Installer XML Toolset (WiX, pronounced "wicks") is a free software toolset that builds Windows Installer packages from XML. It consists of a command-line environment that developers may integrate into their build processes to build MSI and MSM packages. WiX was the first Microsoft project to be released under an open-source license, the Common Public License. It was also the first Microsoft project to be hosted on an external website.

RDF/XML is a syntax, defined by the W3C, to express (i.e., serialize) an RDF graph as an XML document. RDF/XML is sometimes misidentified as simply RDF because it was introduced alongside the other W3C specifications defining RDF and was historically the first W3C official RDF serialization format.

The XML Bookmark Exchange Language (XBEL), is an open XML standard for sharing Internet URIs, also known as bookmarks (or favorites in Internet Explorer).

file format

GraphML is an XML-based file format for graphs. The GraphML file format results from the joint effort of the graph drawing community to define a common format for exchanging graph structure data. It uses an XML-based syntax and supports the entire range of possible graph structure constellations including directed, undirected, mixed graphs, hypergraphs, and application-specific attributes.

XML-based markup language for documenting a person's interests and dislikes

is a specification, governed by a W3C recommendation, that defines how to encrypt the contents of an XML element.

The IMS Question and Test Interoperability specification (QTI) defines a standard format for the representation of assessment content and results, supporting the exchange of this material between authoring and delivery systems, repositories and other learning management systems. It allows assessment materials to be authored and delivered on multiple systems interchangeably. It is, therefore, designed to facilitate interoperability between systems.

XML syntax for digital signatures

The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies.

normal form of XML, intended to allow relatively simple comparison of pairs of XML documents

XInclude is a generic mechanism for merging XML documents, by writing inclusion tags in the "main" document to automatically include other documents or parts thereof. The resulting document becomes a single composite XML Information Set. The XInclude mechanism can be used to incorporate content from either XML files or non-XML text files.

XProc is an XML transformation language for processing documents in pipelines: chaining conversions and other steps together to achieve the desired results. It can handle documents in XML, HTML, JSON, text and binary.

XFrames was an XML format draft for embedding HTML pages into one page which handles the layout without the problems of HTML frames. The frames technique was especially popular for navigation bars. While HTML frames are still supported for legacy websites, today’s websites assemble pages by other means.

GRDDL (pronounced "griddle") is a markup format for Gleaning Resource Descriptions from Dialects of Languages. It is a W3C Recommendation, and enables users to obtain RDF triples out of XML documents, including XHTML. The GRDDL specification shows examples using XSLT, however it was intended to be abstract enough to allow for other implementations as well. It became a Recommendation on September 11, 2007.

Schematron is a rule-based validation language for making assertions about the presence or absence of patterns in XML trees. It is a structural schema language expressed in XML using a small number of elements and XPath languages. In many implementations, Schematron XML is processed into XSLT code for deployment anywhere that XSLT can be used.

XAdES (short for XML Advanced Electronic Signatures) is a set of extensions to XML-DSig recommendation making it suitable for advanced electronic signatures. W3C and ETSI maintain and update XAdES together.

OpenMath is the name of a markup language for specifying the meaning of mathematical formulae. Among other things, it can be used to complement MathML, a standard which mainly focuses on the presentation of formulae, with information about their semantic meaning. OpenMath can be encoded in XML or in a binary format.

WS-Policy is a specification that allows web services to use XML to advertise their policies (on security, quality of service, etc.) and for web service consumers to specify their policy requirements.

PAdES (PDF Advanced Electronic Signatures) is a set of restrictions and extensions to PDF and ISO 32000-1 making it suitable for advanced electronic signatures (AdES). This is published by ETSI as EN 319 142.

XML-based framework

XML Key Management Specification (XKMS) uses the web services framework to make it easier for developers to secure inter-application communication using public key infrastructure (PKI). XML Key Management Specification is a protocol developed by W3C which describes the distribution and registration of public keys. Services can access an XKMS compliant server in order to receive updated key information for encryption and authentication.

thumb|Logo S1000D S1000D is an international specification for the procurement and production of technical publications. It is an XML specification for preparing, managing, and publishing technical information for a product. It was initially developed by the AeroSpace and Defence Industries Association of Europe (ASD) for use with military aircraft. Since Issue 2 the scope has been extended to include land, sea and even non-equipment products. It is widely used in civil as well as military products. S1000D is part of the S-Series of ILS specifications.

xCal is an XML representation of the iCalendar standard. xCal is not an alternative nor next generation of iCalendar. xCal represents iCalendar components, properties and parameters as defined in iCalendar.
