Axiomatization Decision Log
1
Identity-Giving Function
Function class
DivertingFunction
⊑ DesignedFunction
Realized in
DivertingProcess
⊑ FlowControl
All definitions consistently identify diversion/redirection as the identity-giving capability. This function involves redirecting flow, distribution, or material transport from an expected path to an alternative path or destination.
2
Genus Determination
MaterialArtifact
bfo:Object (BFO_0000030)
Monolithic causally unified material artefact.
MaterialArtifact ≡ Object ⊓ ∃bearerOf.DesignedFunction.
No domain-specific parent class is appropriate from the candidates. 'FunctionalObject' from ISO 15926 is too abstract and not part of our IOF-Core framework. 'Piping and pipeline equipment' is too restrictive as diverters exist in many contexts beyond piping. Diverters can be mechanical devices (wellhead diverters, valve-based systems) or chemical agents, all unified by their diverting function rather than a specific structural category.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
Diverters are too diverse in implementation to have universal necessary parts. Some are mechanical devices with bodies and actuators, others are chemical agents, others are flow elements. Parts requirements should be specified at the subtype level (e.g., diverter valve, chemical diverter).
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— material stream in expected flow path
Outputs (O)
PortionOfFluid
— same material redirected to alternative path(s)
Transformation (T)
spatial redirection without chemical or phase change
Core process signature involves taking an input stream and redirecting it spatially. Output count can vary (1+ alternative paths). The material composition remains unchanged - only the flow direction/destination changes.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
Significant variation in application contexts: ISO 15926 focuses on mechanical devices, SLB and OnePetro emphasize oil/gas industry applications including chemical agents, CFIHOS provides the most general definition. The concept spans both mechanical devices and chemical agents, unified by the diverting function.
