This looks like an ontology export bug. The actual datatype is Area http://mappings.dbpedia.org/index.php/OntologyProperty:AreaTotal
and instances of the PopulatedPlace class use squareKilometre http://mappings.dbpedia.org/index.php/OntologyClass:PopulatedPlace
but the owl file we export displays xsd:double we will try to fix this by the next release
The unit may either be specified in property definition or in property data. In latter case it would be helpful to also have a common unit in property definition and (implicit or explicit) rules for conversion (e.g. unit=km2 in property data and unit=m2 in property definition and some external rules for conversion between m2 and km2).
Example: http://dbpedia.org/ontology/areaTotal
I see, that the property label contains "m2", so I would assume that numeric data is specified in square meters. The catch phrase here is "I would assume" - I am human, not a stupid computer system. And even I first had to do some research to figure out that the naked numbers in dbo:areaTotal were square meters.
Or did I miss something?
