This document provides an overview of XML (eXtensible Markup Language). It discusses the basic components of an XML document including tags, elements, attributes, comments, and the XML declaration. It also outlines some of the design goals of XML such as being straightforward to use over the internet and supporting a wide variety of applications. Additionally, it reviews some of the foundations of XML like XML-based markup languages, Unicode, URIs, and defines what a well-formed XML document is.

3. Computer file typesIs just a sequence(stream) of bits( 1s and 0s) Using special encoding

4. Can only be read and produced by special applications

5. meta-data is embedded

6. Process very fastly

7. Any data

8. Using standard encoding

9. Can be read and produced by any application with standard encoding

10. no meta-data

11. Process slowly

13. A brief history of markup 1960’s, in publishing and printing industryThe idea of separation between the contents and formating of a document 1967, William W. TunnicliffeA set of label allowing to describe a so-called editoral structure Stanley RiceGenCodeModern Markup languageCreate a markup language with nested structureGML 1969, Charles Goldfard, Mosher and Raymond Lorie

14. 1986, SGML becomes an international norm(ISO 8879/1986)World Wide Web(WWW) and HyperText Markup Language 1 (HTML 1) 1990, Berneers Lee at CERNExtensible Markup Language 1.0 (XML 1.0) 10 February 1998, XML is a W3C recommandationXML Design goalsXML shall be straightforwardly usable over the Internet.XML shall support a wide variety of applications.XML shall be compatible with SGML.It shall be easy to write programs which process XML documents.The number of optional features in XML is to be kept to the absolute minimum, ideally zero.XML documents should be human-legible and reasonably clear.The XML design should be prepared quickly.The design of XML shall be formal and concise.XML documents shall be easy to create.Terseness in XML markup is of minimal importance.
