Hi Paul and others,

I meant to respond earlier to expand on what I meant by "examples" in  
the telecon on Thursday (and because I will unfortunately miss this  

I think the example and concept illustrations are a good starting  
point.  I agree that it's good to employ high-level examples and  
document how the examples illustrate the concepts, but I think it  
would really help me (and perhaps others) to have concrete examples of  
how the different current proposals would handle examples like the  
data journalism one, so that any disagreement can be discussed in  
concrete terms.

For example, the original "data journalism example" included an OPM- 
like graph and discussion that made it fairly clear how the example  
would be handled in an OPM style.  During the telecon, I think Paulo  
was arguing that other languages such as PML would interpret various  
terms differently, leading to a different interpretation of the  
concepts.  I think the current example/illustration also has this  
flavor, so I would like to see what would change if a PML or other  
style were used instead.

I don't pretend to be an expert on any of the provenance languages/ 
vocabularies being considered so far (my work has been mostly on  
provenance in databases, where there is a lot more variability between  
different techniques).  Are there people who are experts on other  
techniques (PML, Provenir, Provenance Vocabulary) who could add  
examples of how they'd handle the data journalism example to the  
wiki?  I don't mid trying to do so myself, but as a non-expert on the  
other techniques it is not clear that what I would come up with would  
be useful.
