Dear all,

I second the position of Werner to keep ma:compression for the same reasons.

Additionally, I have a problem with the methodology used. This is now a very old subject. Several changes to the ontology have been discussed two telcos ago (and I'll come back in another mail about things agreed and not implemented yet).  The use of MIME types had been discussed before the time of this call and the issue wasn't raised. And here it comes again.

The way the issue is (re-re-re-) presented is also weird. Why say we are back to where we started? There was a proposal. There was motivated disagreement. Hence, no consensus, no change.

End of the story.

Dear Joakim, all,

Thanks for the summary, I'd like to add two points here:
- We should recommend the use of RFC4281 whenever possible, but we cannot rely that they exist for a particular format.
- There is a second reason to keep ma:compression (or codec), which is to describe the encoding of a track rather than a complete file.

Best regards,
