The Edition issues had been discussed yesterday on #matroska. It's seems
to be the most logical way to go.
And about what you say on using chapters and supchapters, it's a
possibility indeed... But how would you distinguish if a top level
chapter is really a normal chapter or is corresponding to a whole album
(in a multiablum mka case). And in a single ablum mka case, where would
you put global tags? This appears to me, more like a problem than like a
Ok, we could in any case use a least one top level chapter to define the
current CD and "attach" to this top lovel chapter all the global tags,
including the MEDIA_PART tag. so we could considere that any top level
chapter that has a MEDIA_PART tag is an album ... else it's a normal
chapter. But won't the be confusing?
About a guide about CD in MKA, I wand to 1) update my guide about it on
HA 2) make a webpage with a more detailed version of this guide with
screenshots :-) I'm just waiting everything to be standardized and fixed
to do / publish it ;-)
With all the work done recently about CD in MKA, I'm pretty sure MKA
will become the standard way to archive audio CDs :-D
