12. Sharing Experiments Taverna supports the in silico experimental process for individual scientists How do you share your results/experiments/experiences with your Research group Collaborators Scientific community How do you compare your results with others produced by e.g. Kepler / Triana / Trident?

14. Recycling, Reuse, Repurposing Paul writes workflows for identifying biological pathways implicated in resistance to Trypanosomiasis Paul meets Jo. Jo is investigating mouse Whipworm infection. Jo reuses one of Paul’s workflow without change. Jo identifies the biological pathways involved in sex dependence in the mouse model, believed to be involved in the ability of mice to expel the parasite. Previously a manual two year study by Jo had failed to do this. Workflows are protocols

15. myExperiment Features User Profiles Groups Friends Sharing Tags Developer interface Workflows Credits and Attributions Fine control over privacy Packs Federation Enactment

16. Just Enough Sharing….And Credit! myExperiment allows you to credit others’ contributions myExperiment allows you to say Who can look at/download or modify your workflow Who can run your workflow Enactment extends accessibility Taverna is for informaticians myExperiment is for informaticians AND laboratory scientists
