AKA arbitrary-collection.The mereological sum of any two or more endurants (physical or not). Arbitrary sums have no unity criterion (they are 'extensional').
Instances of dol:arbitrary-sum can have the following properties:
| PROPERTY | TYPE | DESCRIPTION | RANGE |
|---|---|---|---|
| From class dol:endurant | |||
| dol:life | owl:FunctionalProperty | Total constant participation applied to the mereological sum of the perdurants in which an endurant participates. | dol:perdurant |
| dol:constant-participant-in | owl:ObjectProperty | dol:perdurant | |
| dol:mereologically-coincides | owl:ObjectProperty | Having the same parts at time t. | dol:endurant |
| dol:participant-in | owl:ObjectProperty | dol:perdurant | |
| dol:temporary-atomic-part | owl:ObjectProperty | Having an atom as part at a time t. | dol:endurant |
| dol:temporary-atomic-part-of | owl:ObjectProperty | dol:endurant | |
| dol:temporary-part | owl:ObjectProperty | Being part at time t. It holds for endurants only. This is important to model parts that can change or be lost over time without affecting the identity of the whole. In FOL, this is expressed as a ternary relation, but in DLs we only can reason with binary relations, then only the necessary axiom of compresence is represented here. | dol:endurant |
| dol:temporary-part-of | owl:ObjectProperty | dol:endurant | |
| dol:temporary-participant-in | owl:ObjectProperty | x participates in some of y's parts. | dol:perdurant |
| dol:temporary-proper-part | owl:ObjectProperty | Being proper part at time t. It holds for endurants only. This is important to model proper parts that can change or be lost over time without affecting the identity of the whole. | dol:endurant |
| dol:temporary-proper-part-of | owl:ObjectProperty | dol:endurant | |
| dol:total-constant-participant-in | owl:ObjectProperty | dol:perdurant | |
| dol:total-temporary-participant-in | owl:ObjectProperty | dol:perdurant | |
