This presentation by Jun Zhao, University of Oxford – but missed the start as I presented just now, and getting myself sorted…

Want to use some of the systems/expertise of libraries (esp. digital preservation) to preserve workflows – to make experiments repeatable at any time in the future. Project is ‘Workflow4Ever‘ – http://www.wf4ever-project.org/

Need to be able re-run experiments over data sets as data sets grow – does finding remain true as data grows.

Biology Use case – ‘reuse’:

• Search for existing experiments from myExperiment (http://myexperiment.org)
  • Challenge – understand the workflow
  • Perform test runs with test data and his/her own data
  • Read others’ logs
  • Read annotations to workflows
• Reuse scripts from colleagues and perform test that his/her colleagues are familiar with

Provenance Challenges:

• Identity
• Context
• Storage
• Retrieval
