element are feature, in Croatian case ontology domain will have more
elements than UNGEGN and EuroGeoNames case. On the
figure 11
is a
hierarchy relationship of the ontologies concepts of topographic features
given. Topographic features are matching scale of about 1:200 000. It is,
for example, defining "County center is kind of town, and town is kind of
Settlements".
FIgure. 11:
Hierarchy of the ontologies concepts of topographic features.
Ontological approach of place names in Croatia are used in the moment as
new approach of building place names data model and publish them to the
web. Using open source programs is place names ontology domain defined
using topographic feature as domain elements. After domain elements and
relationships between them are defined, direct output in web of data lan-
guages code could be made.
The comparison of EuroGeoNames, UNGEGN and Croatian domain on-
tologies could not be made completely because it could not be recon-
structed all relations between features defined in each of the system. Here
are presented ontological hierarchical relations between topographic fea-
tures for each of the system as one of relations among ontology domain
