render good labels
wd_wdt:P3373 : http://www.wikidata.org/entity/Q157928
is not really helpful in html. We should display better labels.
we could use wikidata api https://www.wikidata.org/w/api.php?action=wbgetentities&props=labels&ids=P3373&languages=en
or something like this : https://www.wikidata.org/wiki/Wikidata:Database_reports/List_of_properties/all somehow
For gnd, the labels are more self-explanatory :
gnd_dateOfDeath : 1791-12-05
but we could use https://d-nb.info/standards/elementset/gnd.rdf
For viaf, there are various namespaces in use : skos, schema.org, foaf ... https://viaf.org/viaf/75121530/rdf.xml
