The Informatica Connector Toolkit internally uses metadata models to define native metadata objects for the adapter to read from and write to the data source. The metadata model contains components that represent the metadata of the data source.
The Informatica Connector Toolkit uses pattern classes in the metadata model to describe the metadata structure of the data source. The metadata model uses a pattern template to define the metadata pattern of an adapter.
After the Informatica Connector Toolkit registers the metadata model of the data source in the Model Repository Service, you can use the Developer tool to import metadata from the data source.
Do not use the metadata models directly to define the native metadata objects for the adapter. Use the Informatica Connector Toolkit to define native metadata objects.
