different from LUBW Protected Area No (P5965) ?

@Derzno, GPSLeo, Blech, PKM, Ordercrazy, ديفيد عادل وهبة خليل 2: IMHo it makes sense to explicitly point out that this identifier is not a duplicate of LUBW Protected Area No (P5965), though it might seem so at first glance to people not familiar with the topic. I tried to add different from (P1889) to this property, but it seems this cannot be applied here. Is there a more suitable way to do that? --Dealerofsalvation (talk) 15:46, 1 September 2019 (UTC)

I used the LUBW selector [1] to take a closer look at the "Steckbriefe" (Data sheets) from LUBW for Wikidata items having a Baden-Württemberg protected area ID (P6659) and for those having a LUBW Protected Area No (P5965). Samples:

• Aimersbachtal (Q62068250) --> https://rips-dienste.lubw.baden-wuerttemberg.de/rips/ripsservices/apps/naturschutz/schutzgebiete/steckbrief.aspx?id=1369003000047
• Beiberg-Buchberg (Q62026764) --> https://rips-dienste.lubw.baden-wuerttemberg.de/rips/ripsservices/apps/naturschutz/schutzgebiete/steckbrief.aspx?id=929001000003
• Q57992405 --> https://rips-dienste.lubw.baden-wuerttemberg.de/rips/ripsservices/apps/naturschutz/schutzgebiete/steckbrief.aspx?id=1369002000326

In either case, they call the identifier "Schutzgebiets-Nr.", it's just that they use different formats for

• Landschaftsschutzgebiet (Q21503788) and Naturschutzgebiet (Q759421) - sample: "1.36.054" - which match the regexp in this property
• natural monument in Germany (Q21573182) - sample: "81360190024" - which matches the regexp in the other property

So these IDs can be regarded as disjoint. From all of this, I conclude these properties are the same and I suggest merging these two properties into one (extending the regexp to allow both number formats). Thoughts? --Dealerofsalvation (talk) 18:04, 1 September 2019 (UTC)
