Geospatial ontology ・ the meanings for place names ・ reference functions as proper nouns ・ position in coordinate reference systems ・ geometry with coordinates Coordinate referencing Ontology ・ standard for feature discernment ・ general feature model Place name (Toponym) Ontology Feature type Ontology Geospatial Feature Ontology Spatial relation Ontology ・ topology ・ the relations between classes ・ the relations between instances ・ reasoning rules ・ generalization and classification for geographic features ・ category types for places ・ hierarchy of categories
8
Concept and Functions of Place names Place Name ・ By nature of feature ・ By shape of physical object ・ By human name ・ By combining name ・ contains generic class ・ By relative to other names ・ popular name ・ abbreviation ・ By fiction Naming convention Geographic location History (diachronicity) Common knowledge (synchronicity) ・ code translation ・ language translation (phoneme) ・ language translation (meaning) ・ synonymous ・ alternative ・ historical change change It may change its meaning or referenced information Reference The name itself contains and Indicates meanings
