Hello, World!<\/p>\n\n\n\n
This week is a \u201cproblem-solving” week. I really enjoyed this week and I was so excited that I will go to the next step \u201chands-on\u201d part! Professor Bertram and I discussed the Mind Map designed for further research and my questions about understanding provenance models have been solved including OPM, W3C PROV, PROV ONE and the UML graph of prospective and retrospective provenance. In the next week\u2019s meeting, I will give a presentation called \u201c Glimpse of Galaxy history and workflow\u201d, which I would explain more about the content below.<\/p>\n\n\n\n
Prospective and Retrospective provenance<\/strong><\/p>\n\n\n\n To make people understand these two concepts more easily, a graph had been created by Lim, Lu, Chebotko, and Fotouhi (2010). This E-R graph is based on the Open Provenance Model (OPM), so terminologies in the graph are cited from the original OPM. Retrospective provenance is always described as history or records, containing artifacts, agents and processes while prospective provenance is represented by workflows, which are called “recipes”. <\/p>\n\n\n\n
