A technology collaboration specifies which nodes cooperate to perform some task. The collaborative behavior, including, for example, the communication pattern of these nodes, is modeled by a technology interaction. A technology collaboration typically models a logical or temporary collaboration of nodes, and does not exist as a separate entity in the enterprise.
Technology collaboration is a specialization of node, and aggregates two or more (cooperating) nodes. A technology collaboration is an active structure element that may be assigned to one or more technology interactions or other technology internal behavior elements, which model the associated behavior. A technology interface may serve a technology collaboration, and a technology collaboration may be composed of technology interfaces. The name of a technology collaboration should preferably be a noun.
