Synchronized Multimedia Integration Language
     
         (SMIL)
        A language based on {Extensible Markup Language} (XML), that
        enables people without programming or scripting backgrounds to
        author multimedia presentations in a simple {text editor}.
        SMIL is suitable for use on the {World-Wide Web}.
     
        For example, a developer can write SMIL to display an {image}
        after an {audio} track ends.
     
        SMIL uses two main tags: parallel and sequential.  It refers
        to media objects by URLs, allowing them to be shared between
        presentations and stored on different servers for {load
        balancing}.  The language can also associate different media
        objects with different bandwidths.
     
        SMIL 1.0 became an official recommendation of the {World Wide
        Web Consortium} W3C in June 1998.
