Wrong 'globe' in data

Coordinates created with this property has wrong 'globe' component. It points to Earth (Q2) instead of Moon (Q405). Here is dump for mainsnak retrieved from Mare Tranquillitatis (Q320936):

table#1 {
  ["datatype"] = "globe-coordinate",
  ["datavalue"] = table#2 {
    ["type"] = "globecoordinate",
    ["value"] = table#3 {
      ["globe"] = "http://www.wikidata.org/entity/Q2",
      ["latitude"] = 8.5,
      ["longitude"] = 31.4,
      ["precision"] = 0.016666666666667,
    },
  },
  ["property"] = "P8981",
  ["snaktype"] = "value",
}

This is incorrectly rendered in plwiki if the value is retrieved from Wikidata. It is ridiculous to provide dedicated module or method to properly render any new property which has type 'globe-coordinate'. Current data model is flexible enough to manage coordinates on any globe.

Fixed the globe and added a complex constraint. BTW the same happens with P625. --- Jura 20:28, 31 December 2020 (UTC)

• There are items with coordinates that use coordinate location (P625) and located on astronomical body (P376) with Moon (Q405):

SELECT ?item ?itemLabel ?stv
{
  ?item wdt:P625 ?stv .
  ?item wdt:P376 wd:Q405
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}

Try it!

They can be migrated to lunar coordinates (BEING REPLACED) (P8981). Paweł Ziemian (talk) 20:16, 2 January 2021 (UTC)

I started checking which templates need updating. cawiki now supports lunar coordinates (BEING REPLACED) (P8981): ca:Mare_Tranquillitatis with ca:Plantilla:Accident geogràfic extraterrestre and ca:Mòdul:Mapa cos celeste. It seems that many templates for the Moon don't use Wikidata coordinates at all. --- Jura 09:10, 6 January 2021 (UTC)
