SMIL 2.1 became a proposed recommendation in September 2005.

A SMIL document is similar in structure to an HTML document in that they are typically divided between a section and a section. The section contains layout and metadata information. The section contains the timing information, and is generally comprised of combinations of two main tags: parallel ("") and sequential (""). 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 bandwidths.

SMIL enables people without programming or scripting backgrounds to author multimedia presentations in a simple text editor. For example, a developer can write SMIL to display an image after an audio track ends.
