See help documentation on Interoperation for more information on how to interoperate. How to use the data model editor The data model editor uses a tree structure to help visualize the repository's data model. Each class in the data model appears in its own folder. Right-click on the attributes folder to add a new attribute. Right-click on an attribute to change its properties or to delete it.
Attributes can also use vocabularies.
See the discussion on vocabularies below for more information. This description appears in the object editor. Its purpose is to help other repositories that interoperate with your repository understand what the attribute means. This property can be useful in customizing the appearance of the catalog without affecting interoperability. Required attributes must have a value.
