DefinitionAn activity obtained by "selective abstraction" to just that part of an activity that consists in varying or maintaining a specified 'quality' of a participant.
An 'activity profile' is a part of an 'activity', a "selective abstraction" (using a term from the BFO reference guide) made according to a quality of interest to the process. Typically, we will select a physical quantity such as pressure or temperature, and refer to the "pressure profile" of the activity. By means of the relation 'profile quantity datum', the activity profile can be related to a set of 'quantity datum' individuals, to which aggregation can be applied, giving a basis for classification.
Typically, a physical quantity of a participant, such as a "pressure" individual, is selected, and the "pressure profile" of the activity is introduced. The relation 'profile of quality' links to that pressure quality individual that defines (is the basis for abstraction to) the activity profile. By means of the relation 'profile quantity datum', the activity profile can be related to 'quantity datum' individuals, to which aggregation can be applied, giving a basis for classification of the activity profile; for example, as a "rising pressure" activity.
'activity profile' represents a projection of an activity onto a single quality of interest, analogous to the projection of a physical process onto one of its variables. Like a projection in physics, an activity profile unfolds over the same time interval as the containing activity but considers only the variation in some specified quality, such as pressure or temperature.
The name "ActivityProfile" has been chosen because lis:Activity corresponds to BFO's 'process'.
