Workflow Evolution: TracingWorkflows Through Time

Nelson Araujo, Roger Barga, Eran Chinthaka, and Beth Plale


Scientists working on eScience environments use workflows

to carry out their experiments. Since the workflows

evolve as the research itself evolves, these workflows are

a good tool to track the evolution of the research. Scientists

can trace their research and associated results through

time or even go back in time to a previous stage and fork

to a new branch of research. In this paper we introduce

the workflow evolution framework (EVF), which is implemented

in the Trident workflow workbench[5]. The primary

contributions of the EVF include i) management of knowledge

associated with workflow evolution and ii) enabling

reproducible research. Since we believe evolution can be

used for workflow attribution, our framework will encourage

researchers to share their workflows and get the credit

for their contributions.
