Can we tighten the English label somehow?

I'd like harmonize the English labels of this property and Memorial Book Bundesarchiv ID (P7571) somehow. Vienna and University should probably be included in the label in some form, but I'm having trouble coming up with anything that isn't longer than my attention span. Maybe someone has an idea? Ideally, we'd find some scheme that works for Memorial Book Bundesarchiv ID (P7571) and YVNG ID (P7624) as well, since those are even less informative right now. --Matthias Winkelmann (talk) 11:33, 25 November 2020 (UTC)

• “Memorial Book Bundesarchiv ID” seems fine for Memorial Book Bundesarchiv ID (P7571)
• “Memorial Book Univ. Vienna ID“ for Memorial Book University of Vienna ID (P8821)
• “Yad Vashem Shoah Victims ID“ for YVNG ID (P7624)
