Axiomatization Decision Log
1
Identity-Giving Function
Function class
ElectricalDistributionFunction
⊑ DesignedFunction
Realized in
ElectricalDistributionProcess
⊑ PlannedProcess
ISO 15926 states the purpose — 'used to distribute electricity' — while constraining the construction: one or more cable connectors held together with an overall sheath.
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 an ELECTRICAL CONDUCTOR; MaterialArtifact is the corresponding IOF root.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
Parts named in the differentia are not asserted as necessary_parts: validate_necessary_parts_quotes() requires each part to carry a verbatim source_quote, and these come from the definition of this entry itself rather than from a standard stating a component relationship. Left empty pending expert review.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
—
Outputs (O)
—
Transformation (T)
distribution of electricity along a sheathed conductor assembly
No admissible participants: electrical power is not a material entity (ODR-010 §5.1). The cable's electrical rating is a quality (bearer_of ElectricalCurrent, COPI_0000383).
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
The ISO differentia is constructive (sheath, connectors); under OWA structural conditions cannot be sufficient.
Reviewer Notes
ODR-022 §13 coverage audit: standard term bearing a DesignedFunction that held a numeric IRI without an axiomatization. Referenced from process_signature of 'cable tray' and differentia of 'cable bundle'. Awaiting expert review.
