Have you ever used UDF ?
Yes. As far as my experience goes, there's not a lot of difference.
I've had no occasion to *write* DVDs on a computer system, so I can
only speak of reading them.
I did not mean using UDF on opticals discs but on regular drives, just
as any other general purpose filesystem. I once considered using it for
file sharing between Windows and Linux instead of the usual FAT and
NTFS. Indeed UDF is natively supported as a read-write filesystem by
both Linux and Windows, natively supports POSIX permissions and does not
suffer from FAT file size limitations. And I was surprised to discover
that the label set by Windows was not the label read by Linux and vice
versa.
It has a set of identifiers, and I observed
that Windows and blkid did not use the same identifier as the label.
I've made no claim about what Windows and blkid do and do not use.
You wrote that the filesystem label was independent of any OS. I just
gave an example of a filesystem for which two different OSes use two
different identifiers as the label.
