[Tagging] V3 to V4 Mapillary image id migration

[Peter Neale]

Hi Kai,
I am having a go at the MapRoulette challenge (and have managed to deal with a few cases already).
However, I need to seek clarification (sorry if I am being a bit "hard of thinking", but I don't want to cause more problems than I cure)
What should I do, if the Mapillary ID= field (or another field, such as "image=") contains a full URL, linking to the Mapillary image, and including a 22 character alphanumeric (v3) Key?  
Should I:
a.  replace the URL with the 22 character v3 key and wait for your bot to find it and translate it to v4?b.  go somewhere (where?) and look up the corresponding v4 key, placing that in the "Mapillary ID=* field"?c.  Do something else?   
 Regards,Peter(aka PeterPan99)

  Hi Mateusz, 
 
 Nope, those old values are gone. People have either deleted them or deleted their accounts all together with the option to remove their photos along with it. They are gone and can not be recovered by Mapillary. 
 
 The manual MapRoulette fix is hoping that another person has a photo of the same object.

  2 - There are ~2.6k "old" values in the key, that match the correct 
   pattern but that have since been deleted from Mapillary. Please give me 
   your opinion on how the automated edit shall handle them: a) remove 
   completely and don't care anymore b) remove the key and put more info 
   in the changeset comment c) leave the old key even though it has no use 
   anymore d) move to old:mapillary=* (or something like that) 
  
  
   Possibly an option E. That would be to do option C, and set up a 
   MapRoulette for people to manually go through and clean up those 
   objects. There may other images already in Mapillary that correspond to 
   the object, remove the mapillary=* if there isn't, or remove the whole 
   OSM object if it is no longer relevant. 
   
   It only really works if there are people motivated to do the 
   MapRoulette. I'll try to find some time to help out on the current one 
   [1], but the one I describe as option E would be significantly bigger. 
  
  
   I would try MapRouelette, just in case someone would be interested. 
   
   After some time remove them, but with clear description in edit 
   (and also in an approved bot edit). 
   
   old:mapillary=* is definitely bad idea, what is the point of linking something 
   that will never be available again? 
   
   PS Just to check: is it maybe caused by extra space or some other whitespace 
   or other easily fixable issue?
