Hi Gilles,
I tested Maik's patch under Ubuntu 16.04(x64). It solves the problem of writing
metadata in image after applying face tag. The metadata shows in the right
sidebar after I clicked "Album->Write Metadata to Images".
These days, I am looking at the "Unavailable" problem: The parameters in
"Metadata Working Group Regions" such as "Area", "Name", "Region List" shows
"Unavailable" even after drawing a tag box. I think, metadata part in digikam
is a bigger part than the last two bugs(372342 and 351866). So far, I have read
the code of how to show the metadata in XMP view, includes the class
MetadataWidget, MetadataListView which showing the metadata, class SetUp,
SetupMetadata, and MetadataPanel which is created after user click the button
to setup tags filters, and these classes decide which item of metadata to show
in the MetadataWidget. Next step, I think I have to look at the code which set
the concrete parameters of "Area", "Name" and "Region List", and how they
worked. I think this will find the reason why they shows "Unavailable".
