This module defines a data model for representing a system component inventory, which can include hardware or software elements arranged in an arbitrary structure. The primary relationship supported by the model is containment, e.g., components containing subcomponents.

It is expected that this model reflects every field replacable unit on the device at a minimum (i.e., additional information may be supplied about non-replacable components).

Every element in the inventory is termed a ‘component’ with each component expected to have a unique name and type, and optionally a unique system-assigned identifier and FRU number. The uniqueness is guaranteed by the system within the device.

Components may have properties defined by the system that are modeled as a list of key-value pairs. These may or may not be user-configurable. The model provides a flag for the system to optionally indicate which properties are user configurable.

Each component also has a list of ‘subcomponents’ which are references to other components. Appearance in a list of subcomponents indicates a containment relationship as described above. For example, a linecard component may have a list of references to port components that reside on the linecard.

This schema is generic to allow devices to express their own platform-specific structure. It may be augmented by additional component type-specific schemas that provide a common structure for well-known component types. In these cases, the system is expected to populate the common component schema, and may optionally also represent the component and its properties in the generic structure.

The properties for each component may include dynamic values, e.g., in the ‘state’ part of the schema. For example, a CPU component may report its utilization, temperature, or other physical properties. The intent is to capture all platform- specific physical data in one location, including inventory (presence or absence of a component) and state (physical attributes or status).
