Qualifiers

Paris Observatory, PSL University (Q461340) currently has this property with qualifiers "preceded by" and "succeeded by".

Given that it's just an identifier, I doubt that these qualifiers are of much use with this property. I'd tend to remove them. --  Docu  at 15:32, 4 August 2013 (UTC)

I do not know... It is an identifier based on a sequence of natural number, so could be natural (and useful) use "preceded by" and "succeeded by"... --Paperoastro (talk) 14:02, 7 August 2013 (UTC)

Mapping of property based on list of observatory codes

The usage of this property is mapped on User:Romaine/Mapping/List of observatory codes based on the primary source of List Of Observatory Codes. This makes it possible to search easily for the item belonging to a code. Romaine (talk) 06:50, 27 March 2015 (UTC)
