An interface is provided between two or more self-describing devices, each having a data store, or two ongoing processes on the same device sharing a common data store. The interface includes a datastream having at least one metavariable that is indicative of at least two or more parameters associated with a device. The datastream occurs between the data store of one transmitting device to the data store or one or more receiving devices or between two or more processes that may or may not share a common data store. The metavariable references or implies a number of other variables and allows devices to effectively communication without knowledge of the underlying variables. The metavariable can be data indicative of the configuration and settings of a device or can be a command altering two or more setting of a device upon receipt of the metavariable by the device. The metavariable also allows the abstraction of commands encompassing two or more variables such that function and conceptual settings can be communicated in one metavariable.
