Re: concept illustrations for the data journalism example

Hi Olaf:

Interesting exercise. Thanks.

I think time is implicit in the example. I don't know if we need to make 
it explicit. It seems it would be tailoring the example to a 
representation language...

This is interesting. This is how I would want to model the example. But 
I think it's clear that our language would have to support notions 
exactly like "Alice downloaded a turtle file". This is the kind of 
provenance that people say all the time and I think it behoves us to 
figure out what we would need to support this kind of notion.

Yes, I think this is an error. The government was supposed to follow the 
same steps in both cases just for consistency.
