SIE.12:5.1 - Equipment Classes Shared by Three Organizations

Two manufacturers and a service partner exchange service observations using a shared equipment-classification module. Each manufacturer also has local classes needed for its own products.

ArrangementConcrete use
Shared coreDescribes the equipment categories needed to interpret the service observations.
Local modulesRetain product-specific distinctions and identify their relation to the shared core.
CorrespondencesState the qualified relations between local and shared classes; different meanings remain visible.
Content decisionThe agreed maintainers decide changes to the shared module within its stated scope.
Release decisionThe participant authorized to release the module publishes an identified edition and its dependency conditions.
ContactA reachable participant receives questions, communicates decisions, and helps route disputes.
Source authorityEach manufacturer retains the authority for its product descriptions and issued source claims.

A participant proposes changing a shared class from “equipment with a replaceable drive” to “equipment serviced through a replaceable drive module.” The second definition changes the classification criterion. Existing service queries can depend on the first meaning.

For this constructed agreement, the maintainers retain the earlier class and introduce a distinct class for the new criterion. The illustrative identifier equip:DriveReplaceable continues to mean “equipment with a replaceable drive”; equip:DriveModuleServiceable means “equipment serviced through a replaceable drive module.” The second module edition contains both definitions and leaves the earlier edition accessible. It asserts no equivalence between the classes.

The manufacturers’ qualified product descriptions supply these discriminating cases:

EquipmentEarlier classNew class
X: its drive can be replaced as a separate part; it has no replaceable drive service module.Included: the drive is replaceable.Excluded: module replacement is not its service arrangement.
Y: its drive can be replaced separately, and the supported service arrangement also provides a replaceable drive module.Included.Included under the module-service criterion.

SIE.11 follows the changed classification need to the actual queries. Two consumer outcomes complete the illustrative transition:

  • The service partner changes its receiving question to module-replacement planning. It adopts equip:DriveModuleServiceable, updates the relevant correspondence and query, and verifies that Y is included and X excluded. The receiving owner accepts that scoped result; SIE.10 validates its integration premises.
  • Manufacturer A retains its spare-drive query against equip:DriveReplaceable. Its required meaning and the qualified X/Y results remain unchanged, so it retains matching evidence for that use. Adopting the new class is not a prerequisite for continuing this query.

The participant authorized to release the module publishes the identified edition with those definitions, dependency conditions, and migration information. Contact supplies the notice; the content decision, product-source claims, and receiving decisions keep the separate remits shown above. The two completed consumer results do not establish migration by every other user. If the two manufacturers require incompatible local criteria, the commons can retain scoped local modules and their qualified correspondences. No broader equivalence is asserted merely to make the shared diagram simpler.
