$ exiv2 -p t Desktop/IMG_0116.JPG | grep -e GPS -e Make -e Model
Exif.Image.Make                              Ascii       6  Apple
Exif.Image.Model                             Ascii       7  iPhone
Exif.Image.GPSTag                            Long        1  596
Exif.GPSInfo.GPSLatitudeRef                  Ascii       2  North
Exif.GPSInfo.GPSLatitude                     Rational    3  XXdeg XX.XXXXX' 
Exif.GPSInfo.GPSLongitudeRef                 Ascii       2  West
Exif.GPSInfo.GPSLongitude                    Rational    3  XXXdeg X.XXXXX' 
Exif.GPSInfo.GPSTimeStamp                    Rational    3  20:23:04.6
Exif.GPSInfo.GPSImgDirectionRef              Ascii       2  True direction
Exif.GPSInfo.GPSImgDirection                 Rational    1  23151/130

That's from a picture taken with an iPhone 4 (some info intentionally obscured).

Now, I've many older digital pictures. I can tag them myself, I'm just wondering what name / format should I use for the GPS tags? Should I just copy the tag names from the iPhone? Is that seen as a more-or-less-standard nowadays? If yes, does it look like it will remain standard for the foreseeable future?

Here is the standards that I can see:

If the existing module(s) or 3rd party software/manufactures adhere to that I don't know.
