[kepler-dev] workflow execution question

[Jianwu Wang]

Hi, Dawid,

    I think your question is about data provenance (you can find an old 
introduction at 
http://www.kepler-project.org/Wiki.jsp?page=KeplerProvenanceFramework). 
Now it is implemented in Kepler. You can enable it by 
Tools-->Instantiate 
Attribute-->org.kepler.provenance.ProvenanceListener. It can record 
comprehensive information of an workflow execution.

Best wishes

Sincerely yours
