Workflow evolution provenance and OPM

This document discusses the evolution of workflows, focusing on the integration of provenance with workflow management. Tommy Ellkvist and Juliana Freire present a framework utilizing OPM (Operational Provenance Model) to illustrate workflows as directed graphs. Nodes represent workflows while edges represent actions, depicting transformations executed by users. The example provided includes an OPM XML schema, showcasing artifacts and processes that record user interactions and data processing. This framework aids in understanding workflow histories and facilitates better data management and collaboration.

  8. Observations • General model • Only contains enough information to traverse the provenance graph • No additional information stored • Different ways of representing workflow design provenance • Edges as actions • Edges as version differences

  9. Observations • What is the time? • How to interpret a time T of a process? • Does interpretation affect querying • Semantics of intervals • Who is the Agent? • Users • Workflow system • The session • Workflow specification • ”OPM Level 2”? • Are ther workflow specifics we want to express

  10. Interoperability
