<div>Hi All,</div>
<div> </div>
<div>Based on feedback and some of the discussions on the PC3 meeting at eScience 2008, we have added a supplementary
<em><strong>Plotting workflow </strong></em>to the challenge that queries the loaded database, plots a graph using it and displays it to the user interactively. This addition is documented at:
<a href="http://twiki.ipaw.info/bin/view/Challenge/ThirdPCWorkflow">http://twiki.ipaw.info/bin/view/Challenge/ThirdPCWorkflow</a>. There is no separate code provided for these and teams are free to implement these using SQL queries and a plotting program like
GNUPlot.</div>
<div> </div>
<div>A few provenance queries that tie provenance from the plotted image to the source CSV files and loaded tables have been added to the callenge queries page:
<a href="http://twiki.ipaw.info/bin/view/Challenge/ProvenanceQuestionsPc3">http://twiki.ipaw.info/bin/view/Challenge/ProvenanceQuestionsPc3</a></div>
<div>You are welcome to add other queries that make use of the supplementary workflow.<br>
</div>
<div>Teams are encouraged to implement these extensions since it poses some interesting queries over provenance that we may not have encountered.</div>
<div> </div>
<div>Best,</div>
<div>--Yogesh</div>
