Hi Karen,

Placing the archive operation before all distribution operations will result in 
_no_ distributed track getting archived. Only source material will be put in 
the archive. That's probably not what you want.

Yes.

No because then the retraction workflow operation handlers do not know that 
something got distributed.

MH-9237: YouTube generates URLs without a "file extension". Currently the 
MediaInspectionService cannot deal with this.
MH-9172: Your first guess is correct. Streaming media cannot be downloaded so 
archiving fails.


Hope that helps,
