Dear all,


On June 7th [1], we agreed on "In a first instance, to define the 
necessary concepts
that allow us  to express the provenance of an invariant view or 
perspective on a thing".
Putting this in practice turns out to be difficult.

While the egg example is interesting, the scenario seems to evolve all  
the time. Also, I
thought that, in a first instance, we may want to look at things that 
are digital, before
seeing how our ideas extend to the non-digital world.

Obviously, we have our data journalism example, but we seem to ignore. I 
think that we ignore
it because:
- it does not focus on changing things
- it is not precise about how information is published/access,
- it is quite long
(I liked what Simon proposed for this example [2] and this inspired me here)

To unblock the situation, I have:
- drafted a smaller example [3], focusing on a file being updated
- tried to illustrate examples of IVPTs in this example
- highlighted an example of IVPT that I don't know how to handle.

In this example, it would be good to see
- where we have consensus
- where we have disagreement
- how we handle the outstanding example (i0) of IVPT

Feedback by email or on wiki welcome!
