Hi Graham, It is on purpose that we didn't define context. In the WG there is a precedent of not defining terms. To name a few: thing, aspect, act upon/with, bear responsibility, goals, steps, assignment, ... So the word 'context' is to be understood with its informal meaning, .... like 'context' already used in the definition of association [1]. As far as your response to Tim is concerned, of course, we can say that if tool:Bob_as_in_run1 prov:contextualizationOf ex:Bob then tool:Bob_as_in_run1 prov:specializationOf ex:Bob given that contextualizationOf is defined as a subproperty of specializationOf. But your solution fails to identify the bundle in which ex:Bob occurred, which led to the poor rating.
