Use of ‘describes’ in definitions of ‘Velocity’ and ‘Angular Velocity’

Open gregfowlerphd opened this issue 1 year ago • 3 comments

According to the definition of ‘Velocity’, a velocity is a process profile--a subclass of occurrent--that describes something. However, according to the Information Entity Ontology, the domain of describes is information content entity, which is a subclass of generically dependent continuant. Hence, no process profile can describe anything, since no occurrent is a generically dependent continuant.

Similar considerations show that the use of ‘describes’ in the definition of ‘Angular Velocity’ is also problematic.

Perhaps this problem could be avoided by using ‘characterized’ rather than ‘describes’ (as do the definitions for many of the other subclasses of process profile)? The definitions would then become:

Velocity: A Process Profile of an object's Motion that is characterized by its Speed and direction with respect to a frame of reference.

Angular Velocity: A Velocity that is characterized by both the angular (i.e. rotational) Speed of an object and the Axis about which the object is Rotating.

(With respect to the second definition, however, I’m not sure whether it’s right to say that an angular velocity is characterized by the relevant axis. What do y’all think?)
