(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. W3C . (2000-04-21)
