Description
The detailed mapping is presented as a set of template instances of the geographic information metadata classes. The template instance of a class is defined by a set of property instances. The description of each property instance is composed of:
· A plus (“+”) sign starting the description of the property instance;
· The property label as appearing in ISO 19115 UML Models (if the property label does not exist, (metadataElementTitle)) ;
· A presence requirement expressed with a cardinality statement between square brackets (“[...]”). This cardinality statement expresses DGIWG requirements which implies possible differences with the ISO 19115 cardinality;
· A colon (“:”);
· The property type name. The property type is implemented as a sub-element of the property. This sub-element can be an instance of the property type or an instance of one of its derived types. In the latter case, the derived type is either an ISO type or an extension type defined in a profile; and
· A property instance statement which describes how the property type is implemented.
Additional information is provided in a Note section, at the bottom of each table.
This hierarchical set of labels acts as an instance template. This template only shows the properties in the scope of DGIWG metadata elements, which encompass the mandatory properties of ISO 19115. The other optional properties of ISO 19115 are not described, but can be present in a real instance.
Additional properties defined in a profile of ISO 19115 compliant with DGIWG metadata can be expressed but are not documented here.
