The Extensive Markup Language (XML) is a format of simple, very flexible text extracted of SGML (the ISO 8879). Initially designed to find the challenges of publishing industry on a large scale electronic, XML also plays a role increasingly important in the change of a wide variety of information on the Web between(among) others.
The set of instruments of the XML helps in the creation of web pages but its utility goes enough beyond this. XML, in the combination with other procedure, does that us it is possible to define the content of a document independently of hisits formatting, manufacture etc. Being easy it to re-use that content in other uses or for other environments of presentation. The XML provides a basic syntax that can be used to share the information among the classes different from computers, different uses, and different organizations without needing for it to happen for many take to the crouch of conversion.
XML was developed by a Group of XML’s Work (originally known as the committee of SGML’s publishing review) formed(trained) under the patronage of the World Wide Web Consortium (W3C) in 1996. It was presided by Jon Bosak de Sun Microsystems by the active participation of a Special Group of Interest in XML (before known as the group of SGML’s work) also organized by the W3C. The members of the group of XML’s work are given in an appendix. Dan Connolly served as the contact of the group with the W3C. The aims(lenses) of design for XML are:
- XML must be usable directly on Internet.
- XML must support a wide variety of applications.
- XML must be compatible with SGML.
- It is necessary to to be easy to write programs that try documents XML.
- The number of optional characteristics in XML must be supported in a minimum, ideally zero.
- The documents XML must be legible for a human being and reasonably clear.
- XML’s design must be prepared rapidly.
- XML’s design must be formal and concise.
- The documents XML must be easy to create.
- The briefness in the bearing performs minimal importance
- This specification, together with the associate standards (Unicode and ISO/IEC 10646 for characters, Internet RFC 1766 for the brands(marks) of identification of language, ISO 639 for the codes of name of language, ISO 3166 for the codes of name of country), provides all the necessary information to understand XML Version 1.0 and to construct programs of computer that tries it.
