<div class='note'>Some of them may be subject to discussion. In particular, regarding the object properties <i>wasControlledBy</i>, <i>wasGeneratedBy</i> and <i>isUsedBY</i>, we did not specify whether they are transitive or not. One may argue that given that an agent can be a process execution, a process execution, e.g., <i>pe1</i>, can be controlled by an agent <i>pe2</i>, which happens to be a process execution that is controlled by an agent <i>ag</i>, and that, therefore, <i>ag</i> (indirectly) controls <i>pe1</i>. The same argument can be applied to <i>wasGeneratedBy</i> and <i>isUsedBY</i>. That said, we are not convinced that these properties should be declared as transitive. In fact, we are more inclined towards specifying that they are not.
