| http://www.w3.org/ns/prov#value | - The definition of the walk???s purpose was confusing to me:?? For therapy ??? patient walking with a nurse or off-unit health professional?? For a purpose other than therapy ??? walking with a definite goal (e.g., walking to elevator)?? For exercise ??? walking along or with family with no observable goalI was unable to reconcile how the researchers differentiated walking with therapy staff or wit
