Many years ago I started work on a timeline editor for SMIL, but it was
just a hobby and I had no actual need for it so it never got very far.
Seeing where Apple's support for it is now, maybe letting it go wasn't a
It's too bad, though, because SMIL serves a role no other spec provides.
If Apple's serious about making good on their anti-Flash agenda
they'll have to at least support SVG animation, which incorporates a
fair bit of SMIL. TTML also offers a lot of promise, and also
incorporates some aspects of SMIL.
The most unfortunate thing about this is that searching for "SMIL" at
the Apple dev site turns up zero results - not even a page noting its
deprecation, or a redirect for the URL they apparently dumped. Clumsy.
