Any 'object' will be the bearer of various 'dependent' entities, but any 'temporal' entity has only an indirect relationship to 'dependent's. This is in line with BFO.
The class Dependent is closely related to "specifically dependent continuant" in BFO (BFO_0000020).
A common need is to relate a measure based on a 'physical quantity' to an 'activity', like average speed to a transport activity. This may not be implemented with an 'average speed' entity that is dependent on the transport. For a suitable representation pattern, see the class 'activity profile' and related resources. A "shortcut" approach may use the relation 'has participant quality quantified as'.
