1. A method of providing a display associated with a high level architecture (HLA) federation execution, the method comprising: (a) generating an HLA federate; (b) joining the HLA federate to the HLA federation execution; (c) subscribing, using the HLA federate, to receive HLA-federation-execution data including at least one of object classes, object instances, object class attributes, object attribute values, interaction classes, interaction class parameters, interaction parameter values, and interaction occurrence data sets; (d) receiving the HLA-federation-execution data while the HLA federation executes; (e) generating a display element; (f) selecting a first one of an object instance, an object class attribute, an interaction class, and an interaction class parameter from among the HLA-federation-execution data, while the HLA federation executes; (g) displaying a first at least one of an object attribute value, an interaction parameter value, and an interaction occurrence data set from among the HLA-federation-execution data with the display element in response to the (f) selecting the first one, while the HLA federation executes; (h) selecting a second one of an object instance, an object class attribute, an interaction class, and an interaction class parameter from among the HLA-federation-execution data, while the HLA federation executes; and (i) displaying a second at least one of an object attribute value, an interaction parameter value, and an interaction occurrence data set from among the HLA-federation-execution data with the display element in response to the (h) selecting the second one, while the HLA federation executes.
