Editing DwC XMP metadata

[asp]

Darwin Core (DwC) is a XMP metadata standard used for sharing biodiversity information. I am working on getting this added to allow researchers in the field to easily add and edit DwC metadata to their images, such as those captured with camera traps.

What is needed to add support to edit Darwin Core (DwC) XMP metadata to XnView?
