VisTrails Overview
VisTrails is an open-source scientific workflow and provenance management system developed at the University of Utah that provides support for data exploration and visualization. Whereas workflows have been traditionally used to automate repetitive tasks, for applications that are exploratory in nature, such as data analysis and visualization, very little is repeated---change is the norm. As an engineer or scientist generates and evaluates hypotheses about data under study, a series of different, albeit related, workflows are created while a workflow is adjusted in an interactive process. VisTrails was designed to manage these rapidly-evolving workflows. VisTrails streamlines the creation, execution and sharing of complex visualizations, data mining, simulations and large-scale data analysis applications. By automatically managing the data, metadata, and the data exploration process, VisTrails allows users to focus on the task at hand and relieves them from tedious and time-consuming tasks involved in organizing the vast volumes of data they manipulate. VisTrails provides infrastructure that can be combined with and enhance existing visualization and workflow systems.
