Axiomatization Decision Log
1
Identity-Giving Function
Function class
SampleCollectionFunction
⊑ ContainmentFunction
Realized in
SampleCollectionProcess
⊑ MaterialContainment
Vessel's own function (ContainmentFunction) is too generic to distinguish a sample vessel from any other container; SampleCollectionFunction narrows it to the specific collect-hold-transport-for-analysis purpose stated verbatim in both cross-source definitions.
2
Genus Determination
Vessel
Parent candidate CONTAINER is not itself enriched; Vessel (already enriched, function=ContainmentFunction, exported) is the closest enriched supertype and matches the physical form (a container).
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
No specific structural component is named in either cross-source definition beyond the container itself.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— a process sample diverted for analysis
Outputs (O)
PortionOfFluid
— the same sample, preserved intact, ready for delivery to analytical equipment
Transformation (T)
a process sample received, held without loss or contamination, and made ready for transport to analytical equipment
Passive containment signature, matching the genus Vessel; no transformation of the sample itself occurs.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
ISO 15926-4 and CFIHOS definitions are near-identical. CFIHOS's own hierarchy lists 'subsea tool' as an alternate parent candidate (T1_categorical-adjacent, since ISO 15926-4 treats it as a generic CONTAINER while CFIHOS's classification tree places it under subsea tooling) -- not used as genus here since Vessel/CONTAINER better matches the general, non-subsea-specific use the colleague described.
Reviewer Notes
Step 2b consciously not pursued further: two consistent cross-source primary definitions already ground the purpose-based functional differentia in full, and no structural necessary_parts claim is being made that would need secondary/tertiary quote-grounding. secondary_coverage is 'none' as a result, an honest reflection of effort spent, not a gap.
