What I wanted to do was to have various IPTC/XMP fields written out into a border to confirm various things like ownership, usage licence, caption, colour space etc so that the end users know what to do with the image. As far as LRs capabilities go I can't see how to dynamically write out metadata fields to a border upon export. I know the print module has some more welly but the output file type is limited to JPEG which in some situations is fine but on occasion it's simply not good enough from Adobe products, plus there's no option to automatically ingest the file back into the catalog, plus all the embedded metadata is stripped which in my mind given the state of the laws surrounding orphaned works around the world these days, that last point should frankly be considered criminal. If you have any pointers for me for getting this to work in the export dialog I'd be really very grateful.
