Class Discussion on Feb 18th for IT Foundations

For our classroom discussion we studied the history of xml, html, sgml, and gml. I thought this lecture was very interesting. Our teacher showed us the history of the mark up languages and espcially how to do the xml. XML is Extensible Markup Language. This language specifies a document's stucture and content. It is a simplified version of SGML or a subset which could be called "SGML lite". I found out that this xml makes a document searchabe by a search engine on the internet. XML was developed by the W3C which consists of the XML Working group and the XML Special Interest Group. There are ten goals when working in XML:
1. must be easy to use over the Internet
2. must support a variety of applications
3. must be compatible with SGML
4. must be easy to write programs with that processes XML documents
5. the ideal optional feastures in XML must be kept to a minimum, the ideal would be one.
6. should be clear and easily understood by nonprogrammers
7. should be prepared quickly
8. design must be exact and concise
9. easy to create
10. terseness in XML markup is of minimum importance.
