Synchronized Multimedia Integration Language (SMIL) Boston Specification

This document specifies the "Boston" version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL Boston has the following two design goals: (1) Define a simple XML-based language that allows authors to write interactive multimedia presentations. Using SMIL Boston, an author can describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen. (2) Allow reusing of SMIL syntax and semantics in other XML-based languages, in particular those who need to represent timing and synchronization. For example, SMIL Boston components should be used for integrating timing into XHTML.
