yes, it's definitively better.

Exiv2 has a table of XMP namespace with contents and format of data. I
personalty patch this table to add and update digiKam and kipi-plugins
XMP namespace. Look here :

http://dev.exiv2.org/projects/exiv2/repository/entry/trunk/src/properties.cpp#L181

Note : as you can see DwC namespace is not present here... This will
not mean that we cannot read and write tags in this namespace, but
this want mean that client applications need to know this namespace
contents to play with it.
