Motivation

[edit]

The number assigned by Leser Landshuth (Q1329275) to the gravestones in the Jüdischer Friedhof Berlin-Mitte (Q878485) (Jewish Cemetery on Große Hamburger Straße in Berlin) is found both in the Landshuth estate in the Leo Baeck Institute New York (Q15242248) and in Landshuth's cemetery documentation in the Gesamtarchiv der deutschen Juden (Q67918628) in the Central Archives for the History of the Jewish People (Q2893584) in Jerusalem and in the New Synagogue Berlin - Jewish Center (Q67921113) in Berlin. The collection of photos of the cemetery by Martin Koppenheim (Q89351320) in the Central Archives for the History of the Jewish People (Q2893584), also provides the respective gravestones with the Landshuth ID. Jacob Jacobson (Q1677526)'s book on Jewish weddings in Berlin (Jüdische Trauungen in Berlin 1759-1813 : mit Ergänzungen für die Jahre 1723 bis 1759 (Q87647586)) also refers to this ID. Various sources could be brought together via this Landshuth ID.  – The preceding unsigned comment was added by Von Uebigau (talk • contribs) at 11:44, January 22, 2021‎ (UTC).

Discussion

[edit]
  •  Comment @Von Uebigau: It's not clear what value you intend - your examples should display the number you want as value. It looks like you are linking to a reference work that describes these entries? So that would be a reference source, but I don't see exactly what the values would be. I assume there's no formatter URL that links to a page using this number? Do you know how many of these people actually have Wikidata ID's? If it is only 100 or less it might be best to just use a property like described at URL (P973) to link to these source documents. ArthurPSmith (talk) 18:35, 22 January 2021 (UTC)[reply]

@ArthurPSmith: I had taken this ID as a model: Sprockhoff-ID (P5918). Because various sources use the ID, which cannot always be linked to, described at URL (P973) is not the perfect solution. Moreover, I am not sure whether the link to the InternetArchive remains stable. One could then, for example, link generally with described at URL (P973) to the estate in the Leo Baeck Institute: https://archives.cjh.org/repositories/5/archival_objects/331238 and identify the exact location through the Landshuth ID. A digitisation project is currently planned in which the archival records from the Central Archives for the History of the Jewish People (Q2893584) (CAHJP) will be put online. The Landshuth and Koppenheim estates will be digitised there. In perspective, this could become 2800 personal records in Wikidata.
