Hi

I think that StorageFormat probably should be removed from the ChannelType.
This is supposedly to represent the data storage, like SEED or miniSeed,
but that seems to me to really be a property of the waveform itself and not
the metadata. And because the same waveform can be requested in several
different formats, all of which might share the same stationxml file, it
really doesn't make sense.

This came up in the discussions of SIS (
http://maui.gps.caltech.edu/SIStrac/wiki/SIS/UI).

Pull request is here:
https://github.com/FDSN/StationXML/pull/4

thanks,
Philip

    I agree that the StorageFormat can go. I believe it was in the progenitor (Caltech) schema and was intended to denote SEED versus COSMOS. To restate your point, it only really matter what format the data is available in as opposed to what it's stored in.
