<hypertext, language, multimedia, text, web> (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 web.
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.
