Planning

This ontology provides structures for the remaining lower-level ontologies. It distinguishes between action and coping plans and determines the relationships between different kinds of plans, i.e. the fact that one action plan can have multiple coping plans, but each coping plan only refers to one action plan. Action plans consist of information about the activity and context, while coping plans consist of information about the barrier and coping strategy.

Barrier

This ontology describes possible barriers that can occur when people are attempting to be physically active. In creating this ontology, we focused on barriers that can be overcome by an individual on a day-to-day basis. We thus did not include structural or societal barriers, such as walkability

Coping Strategy

This ontology describes the coping strategies that people can use to either prevent a barrier from occurring, or to deal with a barrier once it has occurred. We have focused on coping strategies that can be implemented in the short term (i.e. doing a lighter exercise when it is to hard) rather than long term (i.e. gaining body strength in order to be able to do a certain exercise).
