Axiomatization Decision Log
1
Identity-Giving Function
Function class
StorageFunction
⊑ ContainmentFunction
Realized in
StorageProcess
⊑ MaterialContainment
Storage is the identity-giving function that makes a basin a basin rather than another type of container. The existing StorageFunction from tank/storage tank concepts applies here, as basins are fundamentally storage containers with specific geometric and installation characteristics.
2
Genus Determination
Vessel
Basin is defined as a container/fluid container in ISO15926 and CFIHOS. The most specific appropriate superclass in our enriched ontology is Vessel (function: ContainmentFunction, genus: Assembly). Vessel captures the containment aspect while being more specific than the generic Assembly or MaterialArtifact. Container/FluidContainer from source hierarchies map to our Vessel class.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These structural parts are minimal necessary components for containment function. Covers/tops are not universal since basins are typically open.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
MaterialEntity
— liquid or solid material to be stored
Outputs (O)
MaterialEntity
— same material, stored and contained
Transformation (T)
none - pure storage/containment
Basins provide storage without transformation of the input material. Input and output are the same material portions, with the basin providing temporary or long-term 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.
Disjointness Axioms
Pipe
Pump
Compressor
HeatExchanger
C4: Pipe, Pump, Compressor, HeatExchanger. Storage containers have fundamentally different process signatures from transport equipment (pipes), energy transfer equipment (pumps, compressors), or transformation equipment (heat exchangers).
Cross-Standard Observations
Significant divergence between industrial/engineering standards (ISO15926, CFIHOS) which define basin as an engineered storage container, versus geological standards (SLB, OnePetro) which define basin as a natural sedimentary depression. This analysis focuses on the industrial equipment definition as indicated by the context.
