Hi Daniel,

Thanks for the clarification.

The ProvRDF doesn't provide definitions of these terms, so I looked at 
them simply from the logic point of view.:)

I guess I should go read DM but it might be faster if I can get an 
answer from you.

Can you give me an example to show that an activity a1 was started by 
another activity a2, while a1 was /not/ actually informed by a2?

Sorry if I am raising a repeated technical discussion. If you or others 
could point me to relevant issues to look at, I would most appreciate 
it. This will help me to decide where this term should belong to in the 
prov-o spec and whether an additional example is needed.
