POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A grouping of activities made according to some range of characteristics. Examples of activity class are: producing, refining transporting, etc. An activity class may be classified by other activity classes. For example, the activity class producing oil may be classified as an exploitation activity, meaning that all activities that are classified as producing oil are also exploitation activities.
