Axiomatization Decision Log
1
Identity-Giving Function
Function class
ElectricalSwitchingFunction
⊑ DesignedFunction
Realized in
ElectricalSwitchingProcess
⊑ PlannedProcess
CFIHOS and ISO 15926 give the same functional definition — 'turns electrical current on and/or off' — with no structural constraint, so the function is identity-giving and sufficient.
2
Genus Determination
MaterialArtifact
bfo:Object (BFO_0000030)
Monolithic causally unified material artefact.
MaterialArtifact ≡ Object ⊓ ∃bearerOf.DesignedFunction.
ISO 15926 types it as an ARTEFACT and a SWITCHING DEVICE; MaterialArtifact is the corresponding IOF root.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
No sub-component is named in any source definition for this term. validate_necessary_parts_quotes() requires a verbatim source_quote for every part, and there is nothing to quote — so no parts are asserted (ODR-022 §10.2).
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
ControlSignal
— command to open or close the circuit, manual or automatic
Outputs (O)
InformationContentEntity
— resulting circuit state
Transformation (T)
establishing or interrupting electrical circuit continuity on command
Energy is not a participant (ODR-010 §5.1): the switch's electrical demand is a quality (bearer_of ElectricalCurrent), while the process participants are the command and the resulting state.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Reviewer Notes
ODR-022 §O6: standard-term component of 'switchboard'. Admitted to the pipeline because it is a term in a source standard AND that standard states it is a component of that equipment (verbatim source_quote in the owning entry). Awaiting expert review.
