Add or load custom metadata from a metadata source for which you create a model and define the model classes, properties, and relationships. For example, you can load a custom resource that represents a Microsoft Access database or a custom program that you use to transform and load data.

Classes define the types of objects that a metadata source contains. When you create a custom model, you create classes to represent the data structures and fields in the metadata source.

Add custom properties to existing metadata in the Metadata Manager warehouse. For example, you can add a property to the Cognos model on the

Model

tab, and then edit the value for the property on the

Browse

tab.

Create relationships between custom objects and objects in the same resource or in other resources. Create relationships to indicate that the objects are associated or to enable data lineage analysis. Before you create relationships between objects, you might have to create relationships between the object classes.
