Axiomatization Decision Log
1
Identity-Giving Function
Function class
ContainmentFunction
⊑ DesignedFunction
Realized in
ContainmentProcess
⊑ MaterialContainment
CFIHOS defines a chamber as 'an enclosed space' and ISO 15926 as an ENCLOSURE 'especially one inside an ARTEFACT'. The identity-giving function is containment, which COPI already declares as COPI_0000025.
2
Genus Determination
MaterialArtifact
bfo:Object (BFO_0000030)
Monolithic causally unified material artefact.
MaterialArtifact ≡ Object ⊓ ∃bearerOf.DesignedFunction.
ISO 15926 types CHAMBER as an ARTEFACT and an ENCLOSURE; 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)
PortionOfFluid
— fluid admitted into the enclosed space
Outputs (O)
PortionOfFluid
— same fluid, held within the enclosed space
Transformation (T)
holding a fluid within an enclosed interior space of an artifact
A chamber holds rather than transforms; input and output are the same portion under containment.
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.
ContainmentFunction is shared with every containing artifact in COPI, so it cannot be sufficient. Interiority is a relational condition, not a sufficient one.
Reviewer Notes
ODR-022 §O6: standard-term component of 'manifold'. 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.
