XMP metadata: how-to?
So I just finished importing my library and I'm looking around to correct some mistakes in my photo collection: for example on the map I can see some photos taken middle of the Atlantic (probably coordinates 0,0) and others were taken in a time where GPS information wasn't even a thing. I would like to edit (hopefully in bulk) the metadata of these pictures to include this information, so:
* Am I correct in assuming I need to edit the XMP metadata?
* Currently there isn't an UI for this right?
* I can't find much information on this file: I know where it needs to be but I can't seem to find the format in which it needs to be.
* I edited the image with GIMP and selected to save it with XMP information... however no additional file appeared, but the filesize increased: how can I instruct GIMP to actually create a file instead of embedding it?
