Dear whomever this concerns,
I was trying to use an ISBN code to reference and source a statement. However, Wikidata does not approve using ISBN as a reference value and demands to create a record of the source material in which one can use the ISBN code as an identifier. I understand that at this point it makes no sense when translated to triples to use the property ISBN as a referencer but was wondering if there shouldn’t be a property “ISBN for source material”? This would make referencing a lot easier and might prevent the cluttering of Wikidata with millions of publications (not even speaking of translated and editions…).
Kind regards, Olivier
