Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FluidDistributionFunction ⊑ DesignedFunction
Realized in
FluidDistributionProcess ⊑ PlannedProcess
The identity-giving function is fluid distribution - headers are designed to either collect fluid from multiple smaller pipes or distribute fluid to multiple smaller pipes. This aligns with the already-enriched 'manifold' class which has the same function.
2 Genus DeterminationDeterminação do Gênero
manifoldbfo:Object (BFO_0000030)
Headers and manifolds serve the same functional role (fluid distribution/collection) but headers are specifically characterized by connecting to 'many smaller pipes' rather than general fluid distribution. Manifold is already enriched in the ontology with FluidDistributionFunction and Assembly genus, making it the appropriate superclass.
3 Differentia SpecificaDiferença Específica
∃connects_to.SmallPipe ⊓ ∃participatesIn.MultiStreamDistributionProcess

Headers specifically connect to many smaller pipes and participate in multi-stream distribution processes.

The key differentia is the specific relationship to 'many smaller pipes' mentioned in the definition. This distinguishes headers from general manifolds that may distribute to various types of connections.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Headers inherit basic manifold parts but specifically require multiple connections to accommodate the many smaller pipes they interface with.
