The common trait of amounts of matter is that they are endurants with no unity (according to Gangemi et a. 2001 none of them is an essential whole). Amounts of matter - 'stuffs' referred to by mass nouns like 'gold', 'iron', 'wood', 'sand', 'meat', etc. - are mereologically invariant, in the sense that they change their identity when they change some parts.
Instances of dol:amount-of-matter can have the following properties:
| PROPERTY | TYPE | DESCRIPTION | RANGE |
|---|---|---|---|
| From class dol:physical-endurant | |||
| dol:host-of | owl:ObjectProperty | dol:feature | |
| dol:physical-location | owl:ObjectProperty | Analytical location holding between physical endurants and physical regions. | dol:physical-region |
| 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 | |
