5. Issue: Adding References to the 2018 Imports of Flanders Arts Institute of organizations[edit]

At the moment, it is not possible to query the revision history of Wikidata properties via the SPARQL endpoint. For Flanders Arts Institute, in order to add references to the properties of organizations imported in 2018 namely, inception date, end date, country, and street address, it is necessary to check if the information has changed since the date of import or not. Only when the integrity of the information is guaranteed, Flanders Arts Institue can add the references to the imported properties.

Description: Items with Flanders Arts Institute Organizations id (P5164) cannot be referenced.
Reason: Wikidata history query service does not support percision on the level of property.
Proposed Solutions: Implemntion of a property that can inquire the required level of percision on Wikidata.
