A helmet, such as used by firefighters, includes a compass mounted on the inside of the helmet in a location that will be easily visible to the wearer when necessary but will be positioned so it will not distract the wearer at other times. the method recited in claim 1. 10. A computer-readable medium having computer-executable instructions for the method recited in claim 8. 11. A computer data signal embodied in a carrier wave readable by a computing system and encoding a computer program of instructions for executing a computer process performing the method recited in claim 1. 12. A computer data signal embodied in a carrier wave readable by a computing system and encoding a computer program of instructions for executing a computer process performing the method recited in claim 8. 13. A computer-readable medium having stored thereon a data structure defining a self-describing a software object to be read by a system registrar module to install and register the self-describing software object within a registration datastore, comprising: a first data field containing data representing a dynamic link library; a second data field derived from the first data field comprising a reserve word module; a third data field derived from the second data field comprising one or more self-describing component data elements; and a fourth data field functioning to indicate the end of each self-describing software object; wherein each self-describing component data elements are extracted by the system registrar module to generate data stored within the registration datastore. 14. The computer readable medium according to claim 13, wherein each self-describing component data elements comprises: a classID attribute containing a globally unique identified for identifying the class; and a classVersion attribute containing a 64 bit version number for the class. 15. The computer readable medium according to claim 14, wherein each self-describing component data elements further comprises: a SyncronizationServices attribute for indicating the synchronization behavior for the software object; a LoadBalancingServices attribute for indicating the load balancing behavior for the software object; a PoolableServices attribute for indicating the pooling feature behavior for the software object; and a JIT_activation attribute for indicating the just in time activation behavior for the software object. 16. The computer readable medium according to claim 15, wherein each self-describing component data elements further comprises: a RoleAccessCheck attribute for indicating members of a specific role permitted access to the software object; and a RoleReference attribute for performing programmatic checks for a specific role and applying different semantic behavior based upon the role membership of a caller to the software object. 17. The computer readable medium according to claim 16, wherein: the software object comprises a COM component object; and each self-describing component data elements further comprises: an InterfaceID attribute for indicating the identity of an interface to the COM component; a QueueServices attribute for indicating an interface to the COM component may be invoked over deferred transports; a ProxyStubClassID attribute for indicating whether an interface to the COM component may be marshalled utilizing a custom proxy stub; and an AutoDone attribute for whether a class within the COM component may be safely deactivated after completion of a call to the COM component. 18. A computer data signal embodied in a carrier wave readable by a computing system and encoding a data structure defining a self-describing software object to be read by a system registrar module to install and register the self-describing software object within a registration datastore, comprising: a first data field containing data representing a dynamic link library; a second data field derived from the first data field comprising a reserve word module; a third data field derived from the second data field comprising one or more self-describing component data elements; and a fourth data field functioning to indicate the end of the self-describing software objec
