XProc and SMIL: Orchestrating Pipelines

Earlier this week I posted a short article about orchestrating XProc pipeline steps using SMIL Timesheets:

As mentioned in there I’m going to be pulling together some potential uses-cases and illustrating them using SVG and/or SMIL.

I have one question for now, I was wondering why the max and min attributes were missing from the Timesheet spec. The max attribute would seem to be a very useful feature for providing time-outs for processes that might take an unacceptable amount of time.

Philip,

This sounds very interesting. I'm looking forward to hear more about the potential use cases.

We wanted to include only minimum set of SMIL modules in Timesheet so that it would be easier to implement. Since there was no use case, which required the use of max and min attributes, we did not include MinMaxTiming module in SMIL Timesheets. However, this does not mean that the MinMaxTiming module could not be included in the future versions of SMIL Timesheets if there a new use cases where it is needed.

Yours,
