novalue and somevalue

novalue and somevalue values are to be expected for some of these entries.

• novalue in Wikidata: The official data says none (for this year)
• somevalue in Wikidata: The official data says we are not sure/unknown (for this year)

The difference to simply having no entry in Wikidata is that it is then not possible to say if the data has been missed, it is none or it is unknown. /André Costa (WMSE) (talk) 11:53, 7 June 2017 (UTC)
