GeoReferenceShape and Instance not matching

[robertschubert]

There are two problems in georeference:

• georeference-instance.json
  • the float values are defined as "@value": "2,5", but should be "@value": "2.5", (note the dot instead of comma)
• georeference-instance.json vs. georeference_shacl.ttl
  • the country defines a pattern in the shacl: ^[a-zA-Z]{2}-(?:[a-zA-Z]{1,3}|[0-9]{1,3})$ which would be something like DE-BY.
  • The example in the shacl says Germany, GER (which would not match).
  • The instance file has "@value": "DE", which also does not match the pattern.
  • The description says Country code as ISO 3166-1, alpha-2; This does not match the pattern also.
  • TODO: Please define how the country should be expressed. It should be consistent over both files
