ex:Country a qb4o:LevelProperty ; qb4o:inDimension ex:Geography ;
skos:closeMatch adgeo:Country .

The levels ex:UnitaryAuthority , ex:GovernmentO ceRegion ,and ex:Country are
defined as instances of the class qb4o:LevelProperty , and the relationship
between them is defined by the property qb4o:parentLevel .
An instance of the Geography dimension is shown next:

rdfs:label '' South East '' @en ; skos:broader ns2:921 .
ns2:921 qb4o:inLevel ex:Country ; rdfs:label '' England '' @en .

The property qb4o:inLevel indicates the level in the hierarchy to which
belongs a level member, while skos:broader defines the parent of a
