Axiom type
LLM classification basis: structure-based → ⊑
The identity is defined by physical structure - being 'one of the conductive parts forming a contact' rather than by a specific function. The differentia is the structural role as a conductive part within an electrical contact assembly.

COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
While this is classified as constructive, the generic function is electrical conduction - providing the physical pathway for current flow within the contact assembly. This is the basic capability that any conductive contact part must have.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
The definition explicitly states this is an 'ELECTRICAL CONTACT' - making this the obvious genus. Though not yet enriched in our ontology, this is the appropriate domain-specific superclass rather than collapsing directly to MaterialArtifact.

MaterialArtifact.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The key differentia is being 'one of the conductive parts forming a contact' - emphasizing its role as a constituent part within the larger contact assembly. The partOf relation captures this structural relationship.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
No component terms are provided in the source standards, and the definition describes this as a basic conductive part rather than an assembly with identifiable subcomponents. As a fundamental component itself, it lacks further necessary subparts at the universal level.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
As a conductive part, it receives electrical current and conducts it through the contact interface. The transformation is pure conduction - maintaining electrical continuity with minimal loss. This signature distinguishes it from insulating or switching components.
