Synchronized Multimedia Integration Language

{{As of|2008}}, the W3C Recommendation for SMIL is SMIL 3.0.

SMIL 1.0 became a W3C Recommendation on 15 June 1998.{{Cite web|url=https://www.w3.org/Press/1998/SMIL-REC|title=Press Release: W3C Issues SMIL as a W3C Recommendation|date=1998-06-15|access-date=2021-04-09|website=W3C|author-first1=Sally|author-last1=Khudairi

SMIL 2.0 became a W3C Recommendation on 9 August 2001.{{Cite web|url=https://www.w3.org/2001/08/smil2-pressrelease|title=World Wide Web Consortium Issues SMIL 2 as a W3C Recommendation|website=W3C|date=2001-08-09|access-date=2021-04-09|author-first=Janet|author-last=Daly|author-first2=Marie-Claire|author-last2=Forgue|author-first3=Saeko|author-last3=Takeuchi}} SMIL 2.0 introduced a modular language structure that facilitated integration of SMIL semantics into other XML-based languages. Basic animation and timing modules were integrated into Scalable Vector Graphics (SVG) and the SMIL modules formed a basis for Timed-Text. The modular structure made it possible to define the standard SMIL language profile and the XHTML+SMIL language profile with common syntax and standard semantics.

SMIL 2.1 became a W3C Recommendation on 13 December 2005.{{Cite web|url=https://www.w3.org/2005/12/smil-pressrelease.html.en|title=World Wide Web Consortium Releases SMIL 2.1 as a W3C Recommendation|author-first=Janet|author-last=Daly|author-first2=Marie-Claire|author-last2=Forgue|author-first3=Yasuyuki|author-last3=Hirakawa|website=W3C|date=13 December 2005 }} SMIL 2.1 includes a small number of extensions based on practical experience gathered using SMIL in the Multimedia Messaging System on mobile phones.

SMIL 3.0 became a W3C Recommendation in December 2008. It was first submitted as a W3C Working draft on December 21, 2006.{{cite web|url=http://www.w3.org/TR/2006/WD-SMIL3-20061220/|title=Synchronized Multimedia Integration Language (SMIL 3.0)|access-date=25 February 2017}} The last draft revision was released on October 6, 2008.{{cite web|url=http://www.w3.org/TR/2008/PR-SMIL3-20081006/|title=Synchronized Multimedia Integration Language (SMIL 3.0)|access-date=25 February 2017}}{{Cite book|url=http://www.xmediasmil.net/|title=Interactive Multimedia for the Web, Mobile Devices and Daisy Talking Books|archive-url=https://web.archive.org/web/20090302083620/http://www.xmediasmil.net/|author-first1=Dick C.A.|author-last1=Bulterman|author-first2=Lloyd|author-last2=Rutledge|date=20 November 2008 |isbn=978-3-540-78546-0|publication-date=November 2008|archive-date=2009-03-02|access-date=2021-04-08|publisher=New York, NY: Springer}}

A SMIL document is similar in structure to an HTML document in that they are typically divided between an optional section and a required section. The section contains layout and metadata information. The section contains the timing information, and is generally composed of combinations of three main tags—sequential ("", simple playlists), parallel ("", multi-zone/multi-layer playback) and exclusive ("", event-triggered interrupts). SMIL 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 bandwidth requirements.

For playback scheduling, SMIL supports ISO-8601 wallclock() date/time specification to define begin/end events for playlists.

SMIL files take either a .smi or .smil file extension. However, SAMI files and Macintosh self mounting images also use .smi, which creates some ambiguity at first glance. As a result, SMIL files commonly use the .smil file extension to avoid confusion.

SMIL was created during a time when structured data using XML was very popular and during a time when Internet Explorer was very popular. Thus "combining" SMIL with other markup languages was considered one of the best current practices of the day.

SMIL is one of three means by which SVG animation can be achieved (the others being JavaScript and CSS animations).

While RSS and Atom are web syndication methods, with the former being more popular as a syndication method for podcasts, SMIL is potentially useful as a script or playlist that can tie sequential pieces of multimedia together and can then be syndicated through RSS or Atom.{{cite web|url=http://www.slideshare.net/adrianstevenson/podcasting-smil-61226|title=Podcasting & SMIL|date=2007-06-07|access-date=2021-04-09|author-first1=Adrian|author-last1=Stevenson|website=slideshare.net}}{{cite web|url=http://gonze.com/rss_plus_time.html|title=Analysis of RSS+Time as a playlist format|date=2003-12-03|access-date=2021-04-09|author-first1=Lucas|author-last1=Gonze|website=Lucas Gonze}} In addition, the combination of multimedia-laden .smil files with RSS or Atom syndication would be useful for accessibility to audio-enabled podcasts by the deaf through Timed Text closed captions,{{cite web|url=http://www.jod.id.au/tutorial/accessible-podcast.html|title=Internet Citizenship: Accessible Podcasting|date=2006-11-22|access-date=2021-04-09|author-first1=Jonathan|author-last1=O'Donnell|author-first2=Peter|author-last2=Batchelor|website=jod.id.au}} and can also turn multimedia into hypermedia that can be hyperlinked to other linkable audio and video multimedia.{{cite web|url=http://www.tomw.net.au/blog/2006/05/podcasting-smil-alternative.html|title=Net Traveller: Podcasting: SMIL Alternative?|date=2006-05-29|access-date=2021-04-09|author=Tom Worthington|website=tomw.net.au}}

VoiceXML can be combined with SMIL to provide a sequential reading of several pre-provided pages or slides in a voice browser, while combining SMIL with MusicXML would allow for the creation of infinitely-recombinable sequences of music sheets. Combining SMIL+VoiceXML or SMIL+MusicXML with RSS or Atom could be useful in the creation of an audible pseudo-podcast with embedded hyperlinks, while combining SMIL+SVG with VoiceXML and/or MusicXML would be useful in the creation of an automatically audio-enabled vector graphics animation with embedded hyperlinks.

SMIL is anticipated for use within Text Encoding Initiative (TEI) documents.{{Cite web|url=http://www.tei-c.org/release/doc/tei-p5-doc/en/html/FT.html|title=14 Tables, Formulæ, Graphics and Notated Music - The TEI Guidelines|website=Text Encoding Initiative|date=2021-03-01|access-date=2021-04-09|version=4.2.1}}{{Cite web|url=http://www.tei-c.org/release/doc/tei-p5-doc/en/html/SA.html#SASYMP|title=16.4.2 Placing Synchronous Events in Time|website=Text Encoding Initiative|date=2021-03-01|access-date=2021-04-09|version=4.2.1}}

SMIL is being implemented on handheld and mobile devices and has also spawned 3GPP, [http://www.3gpp.org/DynaReport/26140.htm 3GPP TS 26.140 Multimedia Messaging Service (MMS); Media formats and codecs] the Multimedia Messaging Service (MMS) which is a video and picture equivalent of Short Message Service (SMS).

SMIL is also one of the underlying technologies used for "Advanced Content" in the (discontinued) HD DVD format for adding interactive content (menus etc.).

The field of Digital Signage is embracing SMIL as a means of controlling dynamic advertising in public areas.{{Cite web|url=http://digsigtoday.com/2008/12/iadea-xmp-300-digital-signage-player-to-support-smil-open-standard/|archive-url=https://web.archive.org/web/20090212192109/http://digsigtoday.com/2008/12/iadea-xmp-300-digital-signage-player-to-support-smil-open-standard/|url-status=dead|title=IAdea XMP-300 Digital Signage Player to Support SMIL Open Standard|archive-date=2009-02-12|date=2008-12-04|access-date=2021-04-09|website=DigSigToday|publisher=Wamzle Creative}}{{Cite web|url=http://www.a-smil.org|title=A-SMIL.org, SMIL for Digital Signage|website=A-SMIL.org|date=n.d.|access-date=2021-04-09}}

Most commonly used web browsers have native support for SMIL, but it has not been implemented in Microsoft browsers. It was to be deprecated in Google Chrome,{{cite web|url=https://groups.google.com/a/chromium.org/g/blink-dev/c/5o0yiO440LM?pli=1|title=Intent to deprecate: SMIL|website=Google Groups|author-first=Philip|author-last=Rogers|date=2015-04-29|access-date=2021-04-09}} but it has now been decided to suspend that intent until alternatives are sufficiently developed.{{cite web|url=https://groups.google.com/a/chromium.org/g/blink-dev/c/5o0yiO440LM/m/YGEJBsjUAwAJ|title=Intent to deprecate: SMIL|author-first1=Philip|author-last1=Rogers|date=2016-08-17|access-date=2021-04-09|website=Google Groups}} Other software that implement SMIL playback include:
