Have I misunderstood something? Why on earth would we copy data from a Jeppesen database which has been made up? There is nothing official about the "identifiers" they have used in your examples. It is simply something Garmin/Jeppesen have adopted. Many VRPs in Europe do have proper identifiers, and when they do, those identifiers are used in SkyDemon.
I know you are trying to be helpful, but just as an example, that link you provided contains many UK VRPs which simply do not exist, or were removed years ago. It is not aviation-grade data.
