That's interesting, apparently there are 2 different notations of the property areaTotal. The one in the mappingserver [1] and live [2] are different from the 'main' one [3] which is the correct one afaik.
In [2] there is no rdf:type recognised although it's declared.

Not sure what's going on here?

Thanks,
Roland

Hi Mohamed,

And what about this one:

{{DatatypeProperty
|labels =
{{label|de|Fläche}}
{{label|en|area total}}
{{label|nl|oppervlakte}}
{{label|el|έκταση_περιοχής}}
{{label|fr|superficie}}
|rdfs:domain = Place
|rdfs:range = Area
}}

To me it appears strange to express the range of this property as Area. I think the area total is expressed in some kind of metrics, like for example 128,37 km². Is this an error or am i missing something here?

Property "areaTotal" uses the SI units, so it should be expressed in square meter. Please have a look on that thread [1], as it was discussing that property in details.


Thanks,
Roland

Hi,
I am adding Dutch labels to the ontology and in the process I'm changing
the old notations to the new coding style.
While working my way through a lot of properties i run into stuff like this:

{{ObjectProperty

| labels =

{{label|en|person function}}

{{label|nl|persoon functie}}

| rdfs:range = PersonFunction

}}

In my opinion it would be more complete/precise if the rdfs:domain is
declared (Person), because obviously this property is intended to
connect Person to PersonFunction.
I am tempted to add it to improve the ontology.
What do you think; how to proceed in a situation like this?

I agree with you.
You can go ahead and improve it.


Thanks,
Roland
