Re: concept illustrations for the data journalism example

Hi Jun,

I think Luc answered the question on the list of concepts.

I've added a bit to make the publication of provenance explicit but not 
what actually goes in the provenance. I ignored the intermediate data 
for generating charts from the statistics tools to simplify things.

Can you add your question to the list of provenancne questions?

Thanks,
Paul

I presume that you meant the list of concepts we got out in the incubator group's final report. I went to check the WG's charter page (http://www.w3.org/2011/01/prov-wg-charter). It didn't list out these concepts. I was only able to find them in the page of [3]. Is [3] also the official charter or just the proposed charter? IMO, I think it will look nice to see either this list of charter concepts properly mentioned in the official charter or something similar to make it more easier to trace.
