12. A method comprising: mapping a group leader service to a group leader device of a device network, the group leader service configured to query devices of the device network to obtain device metadata therefrom, and to process the device metadata for transmission; mapping a local service to a local device associated with the group leader device, the local service configured to receive the processed device metadata from the group leader service for storage thereof; and mapping a global service to a global device in communication with the local device, the global service configured to communicate with the local service to update global-level device metadata based on the stored, processed device metadata, wherein the mappings of the group leader service, the local service, and the global service are performed based on an association of service metadata of each of the services with device capabilities of the group leader device, the local device, and the global device, respectively, wherein the global service, the local service, and the group leader service are associated, respectively, with a global service monitor component, a local service monitor component, and a group leader service monitor component, respectively, and wherein the service monitor components are configured to provide monitor data associated with the at least one device network to the service mapper, the service mapper being configured to map a device network service to at least one device of the at least one device network.
12. A method comprising: mapping a group leader service to a group leader device of a device network, the group leader service configured to query devices of the device network to obtain device metadata therefrom, and to process the device metadata for transmission; mapping a local service to a local device associated with the group leader device, the local service configured to receive the processed device metadata from the group leader service for storage thereof; and mapping a global service to a global device in communication with the local device, the global service configured to communicate with the local service to update global-level device metadata based on the stored, processed device metadata, wherein the mappings of the group leader service, the local service, and the global service are performed based on an association of service metadata of each of the services with device capabilities of the group leader device, the local device, and the global device, respectively, wherein the global service, the local service, and the group leader service are associated, respectively, with a global service monitor component, a local service monitor component, and a group leader service monitor component, respectively, and wherein the service monitor components are configured to provide monitor data associated with the at least one device network to the service mapper, the service mapper being configured to map a device network service to at least one device of the at least one device network. 13. The method of claim 12 comprising: monitoring the device metadata using the service monitor components, the monitoring including: receiving a query request at the global service; determining the local service, based on the query request; transmitting the query request to the local service; determining the group leader service at the local service, based on the query request; distributing a query from the group leader service to group devices of the device network associated with the group leader service, based on the query request; and collecting the device metadata from the group devices.
