If I create a metadata template in Bridge CS4, select Copyright Status and set it to Copyrighted,
any other metadata changes in the template will be applied, but "Copyright Status won't change.
I can't even manually set the Copyright Status from within Bridge. If I try, I get an error message,
"This property cannot be modified."
Here's the workaround — create the template in Photoshop or Illustrator, not Bridge.
Open one of the images in Photoshop or Illustrator, select File Info, enter the metadata,
and select Export. The resulting template will be available in Bridge,
and it can change the Copyright Status.
A fix for this in the next incarnation of Bridge would be greatly appreciated.
