[PP] Give an URI to periods #40

Closed pasqLisena closed 7 years ago

pasqLisena commented 7 years ago

Historical periods should have an URI in order to avoid blank and duplicate nodes in the graph.

Query:

select distinct ?label COUNT(?s) where { 
  ?s a ecrm:E4_Period;
      ecrm:P1_is_identified_by ?label .
} GROUP BY ?label

Proposal: <http://data.doremus.org/period/UUID>. This can also be aligned with dbpedia, e.g. <http://dbpedia.org/resource/17th_century>

What about <http://data.doremus.org/period/17th_century> ?

Why not! But would you be able to name any period you may encounter in the data? It is easy when we talk about plain century but in the data, I can see "20 ème siècle - 2 ème moitié" or "Périodes historiques" or "Révolution française". In short, I think it would be better to provide a UUID to identify the period and add a proper label and sameAs links to wikipedia/dbpedia entities when they exist
