Europeana Entity class constraint test[edit]

Right now we have > 160 000 properties set and 99,999% are Europeana Agents i.e. a person, group... I test set a "type constraint" on this property to see what we learn from the next run of the Wikidata:Database_reports/Constraint_violations/P7704 - Salgo60 (talk) 11:24, 28 December 2019 (UTC)

@Salgo60: I did some work on this: --Vladimir Alexiev (talk) 13:23, 8 January 2020 (UTC)

validation regex[edit]

I tightened the validation regex to this below. @Salgo60: do you agree? --Vladimir Alexiev (talk) 12:59, 8 January 2020 (UTC)

   ^(place|agent|concept|organisation)/base/[1-9]\d+$
@Vladimir Alexiev: I guess you are right I hope we will see the Europeana Entity approach to develop and also contain support for describing depicts of a picture... and add many more things than place/agent/concept/organisation. Maybe the best way forward for Europeana is to reuse the Wikidata ontology.... at least as a start like the SDC project has done - Salgo60 (talk) 13:09, 8 January 2020 (UTC)
