Markup Languages Handout

HTML       hypertext markup language

             Generated by Frontpage

            Open, but not all closing tags required

            Tags have attributes

            One type of SGML

 Dynamic HTML

             Allows web pages to look and act like desktop applications or multimedia productions

            Most is specified in HTML 4.0

            Viewable with only IE 4.0 and Navigator 4.0 and later

            Uses an object oriented view of pages and elements

            Supports Cascading Style Sheets, advances in programming, and dynamic fonts

 XML          extensible markup language

             Makes the data in documents readable by machines, not just humans

            Like HTML, a version of SGML

            Specifies which data are to be displayed, not just how data is to be expressed

            Supports users defining new tags

            Is expected to lead to industry labeling standards

XHTML

             A particular application of XML for expressing web pages

            It is XML without the data

            Could have been labeled HTML 5.0, instead it is XHTML 1.0

            Supports all of HTML 4.0, but now requires all closing tags, and more structure

            Designed to be more extensive (users can define new tags) and portable (handsets, microwaves)

 SGML

             International standard in 1986 for specifying a tag set, such a specification is a DTD

            Designed so that any tag set would be independent of machine or operating system

            Expensive, technical, and difficult to learn; not viewable in browsers

            All the markup languages here are types of SGML

 CFML

             ColdFusion is a web application server that provides tools to create:

dynamic, interactive and data driven Web based applications

            CFML is a set of tags used in ColdFusion pages to:

interact with data sources, manipulate data, and display output

            CFML is used with HTML; files saved as .cfm
