Axiomatization Decision Log
1
Identity-Giving Function
Function class
InformationDisplayFunction
⊑ DesignedFunction
Realized in
InformationDisplayProcess
⊑ MeasurementProcess
The identity-giving function is the capacity to present information visually. Both sources emphasize this as the defining characteristic - ISO 15926 defines it as 'capable of displaying something' and POSC Caesar as 'intended for presenting information'. This distinguishes displays from other information-handling equipment like controllers or transmitters.
2
Genus Determination
Instrument
Display is a specialized type of instrument that presents information to users. While not explicitly listed in parent_candidates, 'Instrument' is the most appropriate genus as displays are measurement/information presentation devices. The existing enriched 'Instrument' class with InstrumentationFunction is the correct supertype. Display differs from general instruments by specializing in visual information presentation rather than measurement or control.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
No component terms are provided in the Known Component Terms list, and the source definitions do not specify necessary internal parts at this universal level. Display subtypes (LED, LCD, etc.) would have specific components, but the universal Display class is defined functionally without mandating specific physical parts.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
InformationContentEntity
— digital or analog signals, data streams, or other information-bearing inputs
Outputs (O)
VisualIndication
— visual presentation of information for human perception
Transformation (T)
information converted from input signals or data into visual presentation accessible to human operators
Displays receive information-bearing inputs (electrical signals, data streams) and transform them into visual outputs that humans can perceive and interpret. This is fundamentally a transduction process converting information from one form (electrical/digital) to another (visual).
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
Both sources agree on the core function of information presentation but differ slightly in emphasis between capability and intention. The ISO 15926 definition is more process-oriented while POSC Caesar is more design-oriented.
