Here’s an excerpt from Jon Udell’s interview with Roger Barga explaining the idea of provenance in art and science.

JU: Explain what you mean by provenance.

RB: Think about it in terms of art. For a given piece of art, we’re able to establish through authorities that it’s original, where it came from, and who’s had their hands on it through its lifetime. Provenance for a workflow result is the same thing. Minimally we want to be able to establish trust in a result. If you think about how that happens, it often starts by considering who wrote the workflow. So with Trident you can click on a result and interrogate the history of the workflow: who wrote it, who reviewed it, who revised it, when it first entered the system.
