Data type External identifier?
editThe property HURDAT HURDAT ID (P502) is described as an identifier per HURDAT (North Atlantic hurricane database) The property has datatype String. But is is described With Wikidata property for authority control (Q18614948). Should the Property therefore have datatype External identifier? Pmt (talk) 21:46, 25 September 2018 (UTC)
- I think the main reason this was initially skipped is that the link varies based on its value. In the meantime, the redirector service takes care of that so this could easily be converted. As you already advertised it on project chat, you might want to Wikidata:Contact the development team and ask for conversion. --- Jura 08:46, 6 October 2018 (UTC)
