All software versions should be modelled per [1].  The sub-section [2]
tells how to associate an inventory object to a software version (to
show which BIOS version a specific host card is running for example).

I don't think 'Inventory.Item.System' is intended to represent a single
host in a multi-host system; 'System' would represent the entire
chassis.  You may want to use 'Chassis' or 'Board' to model a
sub-assembly.
