The Darwin Information Typing Architecture (DITA) specification defines a set of document types for authoring and organizing topic-oriented information, as well as a set of mechanisms for combining, extending, and constraining document types. [1] It is an open standard [2] that is defined and maintained by the OASIS DITA Technical Committee. [3]

Contents

The name derives from the following components:

Features and limitations

Content reuse

Topics are the foundation for content reuse, [5] and can be reused across multiple publications. Fragments of content within topics can be reused through the use of content references (conref or conkeyref), a transclusion mechanism. [6]

Information typing

The latest version of DITA (DITA 1.3) includes five specialized topic types: Task, Concept, Reference, Glossary Entry, and Troubleshooting. Each of these five topic types is a specialization of a generic Topic type, which contains a title element, a prolog element for metadata, and a body element. The body element contains paragraph, table, and list elements, similar to HTML.

Maps

A DITA map is a container for topics used to transform a collection of content into a publication. It gives the topics sequence and structure. A map can include relationship tables (reltables) that define hyperlinks between topics. [7] Maps can be nested: they can reference topics or other maps, and can contain a variety of content types and metadata.

Metadata

DITA includes extensive metadata elements and attributes, both at topic level and within elements. [8] Conditional text allows filtering or styling content based on attributes for audience, platform, product, and other properties. The conditional processing profile (.ditaval file) is used to identify which values are to be used for conditional processing. [9]

Specialization

DITA allows adding new elements and attributes through specialization of base DITA elements and attributes. Through specialization, DITA can accommodate new topic types, element types, and attributes as needed for specific industries or companies. Specializations of DITA for specific industries, such as the semiconductor industry, are standardized through OASIS technical committees or subcommittees. Many organizations using DITA also develop their own specializations.

The extensibility of DITA permits organizations to specialize DITA by defining specific information structures and still use standard tools to work with them. The ability to define company-specific information architectures enables companies to use DITA to enrich content with metadata that is meaningful to them, and to enforce company-specific rules on document structure. [6]

Topic orientation

DITA content is created as topics, each an individual XML file. Typically, each topic covers a specific subject with a singular purpose, for example, a conceptual topic that provides an overview, or a procedural topic that explains how to accomplish a task. [10] Content should be structured to resemble the file structure in which it is contained. [11] [12] [13]

Creating content in DITA

DITA map and topic documents are XML files. As with HTML, any images, video files, or other files that must appear in the output are inserted via reference. Any XML editor or even text editor can be used to write DITA content, depending on the level of support required while authoring. Aids to authoring featured in specialized editors include WYSIWYG preview rendering, validation, and integration with a DITA processor, like DITA-OT or ditac.

Publishing content written in DITA

DITA is designed as an end-to-end architecture. In addition to indicating what elements, attributes, and rules are part of the DITA language, the DITA specification includes rules for publishing DITA content in HTML, online Help, print, Content Delivery Platform and other formats.

For example, the DITA specification indicates that if the conref attribute of element A contains a path to element B, the contents of element B will display in the location of element A. DITA-compliant publishing solutions, known as DITA processors, must handle the conref attribute according to the specified behaviour. Rules also exist for processing other rich features such as conditional text, index markers, and topic-to-topic links. Applications that transform DITA content into other formats, and meet the DITA specification's requirements for interpreting DITA markup, are known as DITA processors.

Localization

DITA provides support for translation via the localisation attribute group. Element attributes can be set to indicate whether the content of the element should be translated. The language of the element content can be specified, as can the writing direction, the index filtering and some terms that are injected when publishing to the final format. [14] A DITA project can be converted to an XLIFF file and back into its original maps and topics, using the DITA-XLIFF Roundtrip Tool for DITA-OT [15] [16] and computer-assisted translation (CAT) tools, like Swordfish Translation Editor or Fluenta DITA Translation Manager, a tool designed to implement the translation workflow suggested by the article "Using XLIFF to Translate DITA Projects" published by the DITA Adoption TC at OASIS. [17]

History

The DITA standard is maintained by OASIS. The latest (current) version is 1.3, approved December 2015. An errata document for DITA 1.3 was approved in June 2018. [18]

It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.

XSD, a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document, to assure it adheres to the description of the element it is placed in.

In computing, RELAX NG is a schema language for XML—a RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema is itself an XML document but RELAX NG also offers a popular compact, non-XML syntax. Compared to other XML schema languages RELAX NG is considered relatively simple.

An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.

Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization identities between security domains. SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal between a SAML authority, named an Identity Provider, and a SAML consumer, named a Service Provider. SAML 2.0 enables web-based, cross-domain single sign-on (SSO), which helps reduce the administrative overhead of distributing multiple authentication tokens to the user. SAML 2.0 was ratified as an OASIS Standard in March 2005, replacing SAML 1.1. The critical aspects of SAML 2.0 are covered in detail in the official documents SAMLCore, SAMLBind, SAMLProf, and SAMLMeta.

XLIFF is an XML-based bitext format created to standardize the way localizable data are passed between and among tools during a localization process and a common format for CAT tool exchange. The XLIFF Technical Committee (TC) first convened at OASIS in December 2001, but the first fully ratified version of XLIFF appeared as XLIFF Version 1.2 in February 2008. Its current specification is v2.1 released on 2018-02-13, which is backwards compatible with v2.0 released on 2014-08-05.

XHTML+RDFa is an extended version of the XHTML markup language for supporting RDF through a collection of attributes and processing rules in the form of well-formed XML documents. XHTML+RDFa is one of the techniques used to develop Semantic Web content by embedding rich semantic markup. Version 1.1 of the language is a superset of XHTML 1.1, integrating the attributes according to RDFa Core 1.1. In other words, it is an RDFa support through XHTML Modularization.

The SAML metadata standard belongs to the family of XML-based standards known as the Security Assertion Markup Language (SAML) published by OASIS in 2005. A SAML metadata document describes a SAML deployment such as a SAML identity provider or a SAML service provider. Deployments share metadata to establish a baseline of trust and interoperability.
