This document sets a framework for geographic information service ontology and the description of 
geographic information Web services in Web Ontology Language (OWL).
OWL is the language adopted for ontologies.
This document makes use of service metadata (ISO 19115-1) and service definitions (ISO 19119) 
whenever appropriate.
This document does not define semantics operators, rules for ontologies, and does not develop any 
application ontology.
In relation to ISO 19101-1:2014, 6.2, this document defines and formalizes the following purpose of the 
ISO geographic information reference model:
— geographic information service components and their behaviour for data processing purposes over 
the Web, and
— OWL ontologies to cast ISO/TC 211 standards to benefit from and support the Semantic Web.
