any other metadata will not be shown (and can't be read or written) .
XMP is basically XML, so the metadata has the labels included (have a look
with a binary editor, like Okteta), which is why Exiv2 can display the
metadata with labels, and without the schema being known to the developers.
So when displaying selected items in the metadata, Digikam can only show
items known at compile time ('hard coded'). You /might/ be able to see
other items when showing the full list (metadata tab in the right bar, XMP
item, click on the button with a screen on it, not the portrait). As I
don't use other metadata than those provided by Digikam, I cannot be sure,
Wrt metadata: There's a lot of information in the different tabs, and they
are grouped according to type/camera/schema. Would it be possible to get
an option to close/open all the subsections in one go (at least in the
configuration dialog: there's a lot of camera-specific parts in the
makernote section, and to most users only a few are relevant...)
With a hint where to look I could try and implement such an option myself
(and submit a patch, ofc).
