1. A computer readable medium having stored thereon a first context subsystem data structure comprising: a first child data structure representing a first subsystem of a configured system; a second child data structure representing a second subsystem of the configured system; and a first parent data structure to the first child and the second child data structures, wherein (i) the first and second subsystems individually provide resources that are identified as provided by the context subsystem and (ii) a contextual relationship of the first subsystem and the second subsystem comprises a hierarchical contextual relationship that is logically distinct from a physical configuration relationship and is also independent of configuration modeling structural constraints; wherein: the context subsystem includes data representing a device; the first subsystem includes a first configured computer system configured to utilize one or more resources of the device, and the first subsystem excludes the device; and the second subsystem includes a second configured computer system configured to utilize one or more resources of the device, and the second subsystem excludes the first configured computer system and the device.
