7.3 The I15 model
7.3.1 Resource Metadata
7.3.1.1 General Properties of the Resource Metadata
The ResourceMetadata object type
5
is abstract; it can only be instantiated through the derived object types: DatasetMetadata with the derived types ElementaryDataset and
DatasetCollection, ServiceMetadata and Application. Those object types are the heart of the I15 model. Those four ExtrinsicObject types represent the concrete ISO19115-2ISO19119
ISO19139-2 encoded metadata instances for which RepositoryItems are available.

It shall be noted that each RegistryObject instance has an objectType attribute which value SHALL be a reference to a ClassificationNode in the ObjectType ClassificationScheme. The objectType for almost all
objects in the information model matches the ClassificationNode that corresponds to the name of their class. So the ObjectType ClassificationScheme has to be extended by adding additional ClassificationNodes to support the
newly defined classes of a RegistryPackage.

28 Every I15 metadata resource entry is described by an ExtrinsicObject which is derived from
the ExtrinsicObject ResourceMetadata. ResourceMetadata is derived from the CitedItem ExtrinsicObject and has an association to the MetadataInformation ExtrinsicObject. Every
I15 catalogue SHALL support the slots, datatypes, classifications related to the ExtrinsicObjects ResourceMetadata and MetadataInformation and the association between
them.
