geometry of the spatial object / feature (lines, polygons).
In this work is EuroGeoNames ontology concept domain defined
using two hierarchical levels. Eight classes on the first level are further
granulated (see Figure 10 ).

Each named place can be associated with one or several geographical
names. It could be the names in different languages or in different forms.
Each geographical name can be properly written in one or several scripts
(Latin/Roman, Greek, Cyrillic, etc.). Because nature of place names, there
ontological relations could be complicated and complex. Ontology model
should be kept as simple as possible to not lose overview of ontological
objects and relations. Too complicated ontologies could be spited in more
ontologies.
