Connector scope
The connector allows to retrieve metadata from a Cognos framework definition file (model.xml file).
By default, the following attributes are populated for the entire scope:

Additional attributes are also filled in depending on the technology and by type of object. To make them appear in DataGalaxy screens, it may be necessary to adapt the screens of the concerned objects. See this article to learn more about screen customization.
The following table details the objects and attributes retrieved, and their correspondences in DataGalaxy :
| Cognos object | DataGalaxy Object | DataGalaxy attributes | Comments |
