I'd like to know what is happening to SMIL Timesheets...

[Philip Fennell-2]

Hello,

The other day I had an idea for an interesting use-case for SMIL
Timesheets, but before I go shooting my mouth-off about the idea, I was
wondering what progress is being made with regard to the 'Working
Draft'.

Any thoughts, feedback or genral comments would be much appreciated as I
hope to be publishing a blog entry about it at O'Reilly in the next
couple of days.


Regards

Philip Fennell

Dear Philip,

Thank you for your email. Currently, the SMIL Timesheets is on hold.  
We are waiting for implementations and use cases, before we try to  
reach the W3C Recommendation status. We want to see both  
implementations and use cases to be sure that the specification meets  
requirements of both implementators and developers. Actually, we have  
already at least three implementations, and thus we are now focusing  
more on use cases. Therefore, it would be very interesting to hear  
more about your use case.

Yours,

Can you pls provide any links to implementations that are public?

Hello,

Sure. Here are the implementations that I'm aware of.

Petri,

Thank you for the information.

The use case I was thinking about was to use SMIL Timesheets to
orchestrate XProc <http://www.w3.org/TR/xproc/> pipeline steps. I think
that the Timing and Synchronization features of SMIL could be used to
define when steps should be processed (serial or parallel) and how they
might be triggered by other steps. XProc is basically a serial XML
pipeline processor, with the option to implement concurrency but there
is no way to explicitly declare which steps should run concurrently.

Here is an example of how Timesheets might be used to execute three HTTP
requests concurrently and with an 11 second time-out.
Notice that I've suggested the use of an 'xml-timesheet' processing
instruction (similar to xml-stylesheet) because embedding the
smil:timesheet element into an XProc pipeline would cause it to be
processed and an error would be raised if a step of that type hadn't
already been declared.


Regards

Philip Fennell
