W3C Invites Implementations of SMIL 3.0 Candidate Recommendation

W3C's SYMM Working Group has published the Candidate Recommendation of
Synchronized Multimedia Integration Language (SMIL 3.0), an XML-based
language that allows authors to create interactive multimedia
presentations. A Candidate Recommendation is a document that W3C
believes has been widely reviewed and satisfies the Working Group's
technical requirements. W3C publishes a Candidate Recommendation to
gather implementation experience. SMIL 3.0 design goals are to:
(1) Define an XML-based language that allows authors to write
interactive multimedia presentations. Using SMIL, an author can
describe the temporal behaviour 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 components
are used for integrating timing into XHTML and into SVG. (3) Extend
the functionalities contained in the SMIL 2.1 into new or revised
SMIL 3.0 modules. (4) Define new SMIL 3.0 Profiles incorporating
features useful within the industry. The SYMM Working Group is
building a test suite help ensure interoperable implementation. The
SMIL 3.0 test suite will provide at least one test case for any
new element or new attribute or new attribute value introduced in
SMIL 3.0 and sufficient tests also for any SMIL 2.1 functionality
that might be impacted by new features of SMIL 3.0.
