The ModelScopeIds property is a collection of references to ModelScope objects. The ModelScope object represents a business object in either the ADAPT model or ISO11783 (potentially other models as well). For example, there is a ModelScope object for the ADAPT Farm class as well as a separate one for the ISO11783 Farm tag (FRM). This coded list of business objects forms the controlled vocabulary we use to specify which objects a given ContextItemDefinition can be used to describe. We have tried to reuse existing controlled vocabularies where ever we could; the language and geopolitical vocabularies we use both point to external sources. In this case; however, we were forced to create our own.
GeoPoliticalContextIds: External controlled vocabulary using FAO Geopolitical Ontology.The GeoPoliticalContextIds property is a collection of references to GeoPoliticalContext objects. The GeoPoliticalContext object represents an entry in an external controlled vocabulary that describes a particular geographic/political domain or organization. This allows us to tag ContextItemDefinitions with a marker that conveys "where" the data it represents is relevant.
