A Collaboration describes the structure of elements that implement a certain behavior. In the Collaboration, the elements are the properties connected with the connectors.

Example of a collaboration

In this example, you can see the Loan Collaboration. The Collaboration contains two properties - CatcherInTheRye and Adele. These are the properties (attributes) and the LibraryItem and AudioRecord are the types of each property. The CatcherInTheRye and Adele are connected with the connector relationship.
