Adding DAHR identifiers en masse

Hello! I am a consultant working with the managers of DAHR on a variety of linked data tasks. We're planning to add DAHR identifiers to around 3600 Wikidata entries in the coming days via QuickStatements. We won't be removing any existing statements, but we may go through later and mark some outdated statements a with end dates. We wanted to check in here first and give folks interested in this property a heads up, and ask whether there is anything we should be aware of. AVP-DAHR (talk) 17:30, 25 September 2023 (UTC)
