Hi Rebecca,

This does not pass the sniff test. Materials exchange format is a standard ratified by the SMPTE. If Sony uses a proprietary variant of MXF, then it is not MXF. If product documentation trumps the SMPTE, the EBU and LC, then we are going to need a bigger handbasket.

Please consider changing the subject line when responding to digests. I am not sure what you are responding to.

FWIW, SoCal Code4Lib is having a meeting this Thursday. You might want to join us. http://www.meetup.com/Code4lib-SoCal/events/219653631/

Thanks,

Cary
