All very well but I still need to know exactly what the Exiv2/XMP
field names are so that, having set a value with Digikam, I can read
it with my script and/or access it from Dokuwiki.

Also, are tags, ratings and written this way.

Looking at http://www.flickr.com/photos/digikam/4970137661/ I can see
under "digikam schema" there is a "Tags List" - how do I work out how
to access that with standard Exiv2 tools/libraries.  Similarly for the
Rating in Basic Schema.

Will all these fields be written by default or are only the "digikam
schema" ones written, or what?

Sorry about all the questions, I really appreciate the support here,
thank you.
