Axiomatization Decision Log
1
Identity-Giving Function
Function class
TubingHangerSeatingFunction
⊑ DesignedFunction
Realized in
TubingHangerSeatingProcess
⊑ PlannedProcess
OnePetro defines it entirely by what it receives: 'a section in a part of the wellhead that accommodates the tubing hanger'. Accommodating and seating the hanger is the identity-giving function.
2
Genus Determination
MaterialArtifact
bfo:Object (BFO_0000030)
Monolithic causally unified material artefact.
MaterialArtifact ≡ Object ⊓ ∃bearerOf.DesignedFunction.
A machined seating profile within the tubing head; MaterialArtifact is the correct 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)
—
Outputs (O)
—
Transformation (T)
seating and sealing of a tubing hanger within the wellhead
No admissible participants: what the bowl receives is the tubing hanger, an equipment part, and ODR-010 §5 excludes artifacts as hasInput/hasSpecifiedOutput fillers.
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.
Definition locates it within the wellhead rather than characterising it independently; parthood is not a sufficient condition.
Reviewer Notes
ODR-022 §O6: standard-term component of 'tubing head'. 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.
