What is Extensible Markup Language (XML)

Extensible Markup Language (XML) is used to describe data. The XML standard is a flexible way to create information formats and electronically share structured data via the public Internet and corporate networks (Doszkocs et al., n.d.).

XML is a set of standards that specify how to structure a text-based document for communication between two computers for any number of purposes. It allows incorporating metadata in the message to be exchanged, so the data may be transmitted and understood by the receiving party.

A W3C-recommended general-purpose markup language for creating special-purpose markup languages, capable of describing many different kinds of data. XML is a way of describing data.

A simple yet powerful computer communication language developed in 1996 by the World Wide Web Consortium (W3C) as a more flexible markup language than Hypertext Markup Language (HTML) for creating Web pages. While HTML is limited to describing how data should be presented in the form of Web pages, XML can perform presentation, communication, and storage of data easily.

XML is a W3C recommended markup language. Unlike HTML, which is for human consumption only, XML is both for human and machine consumption.

Markup language proposed by the World Wide Web Consortium [W3C] for data and documents interchange.

XML provides constructs to support the design of markup languages to facilitate document and data exchange.

Extensible labelling metalanguage developed by the World Wide Web Consortium.

XML is a way to mark up text-based content into a structure that can be interpreted by a computer application that has the schema necessary for interpretation.

A general-purpose specification language that allows creating custom languages by defining language specific markups (or tags).

The novel language, standardized by the World Wide Web Consortium, for representing, handling and exchanging information on the Web.

XML is a standard for creating markup languages that describe the structure of data.

Has been created to overcome some difficulties proper to HTML (Hypertext Markup Language) that – developed as a means for instructing the Web browsers how to display a given Web page – is a ‘presentation-oriented’ markup tool. XML is called ‘extensible’ because, at the difference of HTML, is not characterized by a fixed format, but it lets the user design its own customized markup languages (using, e.g., a specific DTD, Document Type Description) for limitless different types of documents; XML is then a ‘content-oriented’ markup tool.

A set of rules for encoding documents in machine-readable form

A language for creating markup languages. There are two kinds of XML documents: well-formed and valid. The first respects the XML standard for the inclusion and the tag names. The second must be well defined and uses grammar to define the structure and the types of data described by the document

Document type definitions that can be used to specify or describe various types of objects. When a set of these is used on the Web to describe product information, it is referred to as cXML or commerce XML. It works as a meta-language that defines necessary information about a product, and standards are being developed for cXML in a number of industries, performing a function similar to that of EDI for non-Web-based systems. It will help to standardize the exchange of Web catalog content and to define request/response processes for secure electronic transactions over the Internet. The processes include purchase orders, change orders, acknowledgments, status updates, ship notifications and payment transactions.

It standardizes the exchange of Web catalog content and defines request/response processes for secure electronic transactions over the Internet. The processes include purchase orders, change orders, acknowledgments, status updates, ship notifications and payment transactions.

A structured language utilized for information exchange, standards and information validation via the use of schemas. Its extensibility allows developers and experts to design and implement common standards for the use across systems and domains.

is a W3C-recommended general-purpose markup language for creating special-purpose markup languages, capable of describing many different kinds of data. In other words, XML is a way of describing data.

A general-purpose markup language designed to be reasonably human-legible, and therefore, abruptness was not considered essential in its structure. Its primary purpose is to facilitate the sharing of data across different information systems, particularly connected through the Internet, and to allow for diverse software to understand information formatted in this language.

A general-purpose specification for creating custom markup languages. It is extensible because it allows users to define their own elements.

A markup language combines text and extra information about the text. The extra information, for example about the text’s structure or presentation, is expressed using markup, which is intermingled with the primary text. The best-known markup language in modern use is HTML (hypertext markup language), one of the foundations of the World Wide Web. Another, newer, markup language that has gained great importance is XML (extensible markup language). XML was developed by the World Wide Web Consortium. The main purpose of XML was to simplify SGML (Scribe General Markup Language) by focusing on a particular problem — documents on the Internet. XML remains a meta-language like SGML, allowing users to create any tags needed (hence “extensible”) and then describe those tags and their permitted uses.

A text-based data transfer protocol that consists of metadata tags that enclose data values. These tags can enclose other tags to form a nested structure. An example, <Person><Name>John Doe</Name></Person> indicates a Person record with a field of Name whose value is John Doe.

XML, describes a class of data objects called XML documents and partially describes the behavior of computer programs which process them. XML is an application profile or restricted form of SGML, the Standard Generalized Markup Language. By construction, XML documents are conforming SGML documents.
