Perhaps it helps if people can explain which problem is to be solved
with the inventory data model. The ENTITY-MIB primarily exports the
internal structure of a physical device (a containment hierarchy of
physical components) to management applications. Some extensions
provide access to more detailed state information and to sensors often
attached to hardware components. Most of this is not configurable
(although you can attach deployment specific identifiers and
descriptions).

Can someone provide a concise description which problems the inventory
data model is trying to solve? Is it essentially adressing the same
functionality as the ENTITY-MIB or something different? If so, I
assume there is not much too configure - a few 'postit' objects and
perhaps an administrative state object.

PS: I am attaching the combined tree of the ENTITY*MIB modules
    published by the IETF.
