[provenance-challenge] clarifying queries

[Paul Groth]

Hi Everyone,

There have been some concerns about the specificity of the Core  
Queries. Looking through the team pages I think everyone came up with  
reasonable interpretations for these queries.

To address this concern, I made a detailed version of Query 1, which  
you can find on the PC3 Questions page (http://twiki.ipaw.info/bin/view/Challenge/ProvenanceQuestionsPc3 
). This detailed version identifies more concretely what items we are  
finding the provenance of, the expected outputs, and a describes how a  
traversal over the provenance graph could be performed.

If you have time, it would be interesting to see if your queries  
results and interpretation were in-line with this more detailed  
expression of Query 1.

Thanks,
Paul
