Timesheets - UA Capability Detection

Hello all,

Is there a standard, recommended technique for detecting browser capability when it comes to SMIL? You may be aware of the FakeSmile library: http://leunen.d.free.fr/fakesmile/

I would like to see hwo hard it would be to implement support for SMIL Timesheets 1.0 into this library, but I would like to 'future-proof' the library such that if (when) browsers start supporting it natively that the script does not run.

I would like to be able to do this in Firefox, Opera, Safari, and Internet Explorer.

Thanks,
Jeff

A DOM feature string sounds like the way to go, here, so you could do:

  if (document.implementation.hasFeature("Timesheets", "1.0"))
      …

Re: Timesheets - UA Capability Detection

Thanks, Cameraon for the suggestion.

SYMM Working Group,

Can we have a response on this? I think the feature string hasFeature() check is a good idea, but the feature string would need to be defined in the spec. "org.w3.smil.timesheet" ?

Thanks,
Jeff

Jeff,
do you have examples of other specs that have such a reference? The  
suggested functionality sounds pretty useful, but it would fall under  
a "best practices" or "integration suggestions" heading, and we  
haven't done such before...

Re: Timesheets - UA Capability Detection

Jack,

http://www.w3.org/TR/DOM-Level-2-Core/core.html#ID-5CED94D7 is the DOM hasFeature method. It mentions how the SVG did things, which is here: http://www.w3.org/TR/SVG11/feature.html and http://www.w3.org/TR/SVG11/svgdom.html#FeatureStrings

Regards,
Jeff

Re: Timesheets - UA Capability Detection

Jeff,

The unique identifier of the timesheet module seemed to be : http://www.w3.org/2007/07/SMIL30/Timesheets

I don't know whether this is still valid though, since Timesheets has been removed from SMIL3...

timesheets priorities

Hello all,

The animation sandwich model states that the document order of the elements have an influence on the animations priority :
"If two animations share no time dependency relationship the element that appears first in the document has lower priority."

Can anyone tell me what is the expected behavior for an external timesheet ?
Are the elements contained in the external timesheet to be considered at the <timesheet>/<link> position ? Or do external animations always have lower priority compared to inline ones ?

Thank you!

David
