"ARENDAL"	"POINT(8.76827271306773 58.4417958162972)"	"Geographical Location (GL) part of the Nordic 44-bus synthetic test model developed by Statnett SF of the Nordic region."
"ARENDAL"	"POINT(8.77315129409427E0 5.84640187084885E1)"	"DIGIN10-30-MV1_GL"

You see that the Telemark (DIGIN10) coordinates are slightly different.

• This difference causes 3 duplicate PowSyBl diagram record to be generated in Talk2PowerSystem:

• Furthermore, the Telemark coords are in scientific notation. This will throw off many geo processing software who expect simple decimal.
  The reason is that they are emitted as numbers in JSON-LD: instead, should be emitted as strings.

This issue comes down to "Which Modeling Authority should (or is allowed to) produce data about a PSR?".

From this point of view, it's more complex than that issue, which is about duplicated data by one Modeling Authority.
