The metadata pattern of a connector describes the metadata structure of the native data source. You can choose a metadata pattern template to define the metadata pattern of a connector.
A metadata pattern template is a set of packages such as catalog, container, flat record, and so on. Sets of related classes that define the metadata pattern are organized as packages.
Though a connector can have more than one metadata pattern, the Informatica Connector Toolkit currently supports only Type A template. The type A template provides the metadata patterns for flat records. You can use the metadata catalog that the Type A template provides to describe the metadata structure of the data source.
