Our layout will try to capture the relationship between nodes (which for our current purposes means motherboards) and devices (any network/communication device). The relationship heirachy looks like this:
{{{
TESTBED -
         |
         -> Node -
            -INV_... -- Inventory Attributes (e.g. motherboard serial number, disk size, cpu type,...)
            -INF_... -- Infrastructure Attributes  (Control IP, Control interface,...)
            -CM_...  -- CM attributes (e.g. CM IP, CM Version, ...)
                 |
                 -> Device
                    -name = FQDNofNode_dev_unique#
                    -INV_if_name= "name the os thinks this device is. (e.g. eth0)"
                    -INV_dev_id = "xxxx:xxxx" where the x's are hex numbers that represent the device identifiers. 
}}}

To reflect these relationships we're going to establish a few naming conventions. These will be enumerated in the following table
||Hardware || resource type || name || attributes (all prefixed with INV_)||
||Mother board|| Node || FQDNofNode || disk, cpu, memory, mother board serial number, disk serial number ||
||Wired ethernet card || Device || FQDNofNode_DEV_unique#  || mac, device id, device string, bus type ||
||Wireless ethernet card || Device || FQDNofNode_DEV_unique#  || mac, device id, device string, bus type ||
||USB connected device || Device || FQDNofNode_DEV_unique# || mac (if it exists), device id, device string, bus type ||
