In NAF 4 and UAF, a data construct that is part of a Data Model, flows between OperationalPerformers and is produced, and is consumed by the OperationalActivities that the OperationalPerformers are capable of performing. This concept is the same as the Entity concept that System Architect supports in its data modeling. In the UAF domain metamodel on which NAF v4 is based, Entity is renamed under the covers to InformationElement. It contains attributes, which themselves are local instantiations of Data Elements. Previously, in DoDAF 2, users would model the Data (DM2) concept, and specify the Entity that the Data (DM2) represented. Now users may directly specify InformationElements (which are represented on logical data models) in the architecture.
