Synchronized Multimedia Integration Language
open-in-new
<p>Synchronized Multimedia Integration Language (SMIL (/smaɪl/)) is a <a href="/facts/World_Wide_Web_Consortium/lGWmhF6M">World Wide Web Consortium</a> <a href="/facts/W3C_recommendation/lGWmhF6M">recommended</a> <a href="/facts/Extensible_Markup_Language/clNgUfWk">Extensible Markup Language</a> (XML) <a href="/facts/Markup_language/WwhlNVIu">markup language</a> to describe <a href="/facts/Multimedia/PtJteq27">multimedia</a> presentations. It defines markup for timing, layout, animations, visual transitions, and media embedding, among other things. SMIL allows presenting media items such as text, images, video, audio, links to other SMIL presentations, and files from multiple web servers. SMIL markup is written in XML, and has similarities to <a href="/facts/HTML/sSc3fT78">HTML</a>. </p><p>Members of the <a href="/facts/World_Wide_Web_Consortium/lGWmhF6M">World Wide Web Consortium</a> (also known as the "W3C") created SMIL for <a href="/facts/Streaming_media/4rPhSq0Y">streaming media</a> presentations, and published SMIL 1.0 in June 1998. Many of these W3C members helped author several versions of SMIL specifications between 1996 (when the first multimedia workshops were hosted by the W3C) and 2008 (when SMIL 3.0 was published). SMIL is an XML-based application, and is a part of many <a href="/facts/Multimedia_Messaging_Service/Pg5CvwLx">Multimedia Messaging Service</a> (MMS) applications. SMIL can be combined with other XML-based specifications such as with SVG (as has been done with <a href="/facts/SVG_animation/bGVyDGsl">SVG animation</a>) and with XHTML (as done with <a href="/facts/HTML%252BTIME/NE1MWIzv">HTML+TIME</a>). </p>
