Ah, OK, thank you.

Absolutely!  It's all a bit of a can of worms and I realise that
Digikam is doing its best to handle it all in a reasonable way.

OK, but it would still be very useful to be able to find this
information.  I know some are described in detail in the
Metadata->Advanced tab in Settings but it would be good to know how
all are handled.  Maybe the section in Settings could be extended?

Anyway, thank you for your reply, I know this is a rather 'messy' area
in handling image files so there is no easy answer.
