lightroom-xmp-export

This Lightroom plugin will extend the XMP files written by Digikam with the data from the Lightroom database.

This is particularly useful to transfer metadata of video files, since Lightroom doesn't write XMP files for them.

The following metadata is supported:

• keywords
• city
• province/state
• location
• country (the country code needs to be set in Lightroom though to be imported correctly in Digikam)
