XML is a software- and hardware-independent tool for storing and transporting data. These tags are "invented" by the author of the XML document. Imagine an application designed to display the original version of note. Then imagine a newer version of note. Many computer systems contain data in incompatible formats.
Exchanging data between incompatible systems or upgraded systems is a time-consuming task for web developers. Large amounts of data must be converted, and incompatible data is often lost. 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 language s that describe the structure of data. A language for creating markup language s. 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 Learn more in: ScaleSem Approach to Check and to Query Semantic Graphs.
Document type definitions that can be used to specify or describe various types of objects. It works as a meta- language that defines necessary information about a product, and standards are being developed for c XML in a number of industries, performing a function similar to that of EDI for non-Web-based systems. 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. 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 language s. It is extensible because it allows users to define their own elements. A markup language combines text and extra information about the text.
Another, newer, markup language that has gained great importance is XML extensible markup language. 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. XML , describes a class of data objects called XML documents and partially describes the behavior of computer programs which process them. Publishing companies needed a means for marking up a document so that the words could be presented in a number of different ways.
Both documents may require the publisher to re-use elements of the original. Coding a document in SGML permits the text to be re-used in many different formats. The standards process fine-tuned a rich document markup language that allowed the author to separate the content from the presentation of document. Authors could write once, tag with SGML, and display the information in many different formats. SGML is not a language in itself, it is a meta-language.
The main purpose of SGML is to describe a method for describing data. It provides a method for depicting any logically structured set of information. A meta-language is a set of rules that defines how other things work. As a meta-language, SGML provides the overall rules and procedures that permit a wealth of varied applications to exist. No real games are held directly by the Olympic committee, but the structure and participation criteria are developed and enforced at this level.
Taking a step closer to the actual games such as the summer Olympic games, the protocol HTML hyper-test markup language is similar to the rules developed for participation in demonstration sports; few rules, no official metals are awarded and not a lot of athletes participant.
Any disputes or questions about the rules are handled by the Olympic committee. The W3C recommendation 4 for XML laid out the rules for creating a markup system that would give context and structure to data.
