Composition of an individual

Introduction

Instances of PossibleIndividual may be composed of other instances of PossibleIndividual. The Part 2 data model distinguishes a few flavors of composition:

The subtypes Participation, TemporalWholepart, and TemporalBounding have been discussed elsewhere. We will discuss the three entity types that apply to instances of ArrangedIndividual in the 'whole' role: ArrangementOfIndividual, AssemblyOfIndividual, and FeatureWholePart.

The typical model for composition, in template format, is:

Template for an instance of ClassOfCompositionOfIndividual

Template for an instance of CompositionOfIndividual

The analysis diagram for the above case is as follows.

Now the templates for the three subtypes, that involve an ArrangedIndividual, follow below (for my convenience I leave the IDs the same). We start with the ArrangementOfIndividual:

Template for an instance of ClassOfArrangementOfIndividual

Template for an instance of ArrangementOfIndividual

Then the template for AssemblyOfIndividual:

Template for an instance of ClassOfAssemblyOfIndividual

Template for an instance of AssemblyOfIndividual

And finally the FeatureWholePart:
