Wikidata entry structures
WikidataEntry represents the data ready to be inserted
in our database.
WikidataEntryKey is a subset of WikidataEntry to identify
a set (FANTOIR code, Wikidata item) to be used as HashMap key
when a SPARQL query returns several rows for such set.
For example, here, we ask for P31 values, and if a Wikidata
entity offers several P31 values, we'll get one row per value.
