Wf4Ever project Wf4Ever was a research object funded by EU Framework 7 to investigate how scientific workflows and their data could be better preserved for reproducibility, reuse and resiliance against workflow decay.
Tracking workflow execution with TavernaProv
Apache Taverna is a scientific workflow system for combining web services and local tools. Taverna records provenance of workflow runs, intermediate values and user interactions, both as an aid for debugging while designing the workflow, but also as a record for later reproducibility and comparison.
Taverna also records provenance of the evolution of the workflow definition (including a chain of wasDerivedFrom relations), attributions and annotations; for brevity we here focus on how Taverna’s workflow run provenance extends PROV and is embedded with Research Objects.
