Motivation

Create reproducible science by documenting data provenance: processes used to create, modify, visualize, analyze, and synthesize data

Challenges: Standard tools (e.g., R) do not collect provenance Specialized tools (e.g., Kepler) have steep learning curve

Computer scientists are interested in control flow, data flow, abstraction; ecologists are interested in other things

Lack of community standards How much information to collect, manage, store, and use
