Towards the Preservation of Scientific Workflows
- Some of the shared digital artefacts of digital research are executable in the sense that they describe an automated pro- cess which generates results. One example is the compu- tational scientic work ow which is used to conduct auto- mated data analysis, predictions and validations. We de- scribe preservation challenges of scientic work ows, and suggest a framework to discuss the reproducibility of work- ow results. We describe curation techniques that can be used to avoid the `work ow decay' that occurs when steps of the work ow are vulnerable to external change. Our ap- proach makes extensive use of provenance information and also considers aggregate structures called Research Objects as a means for promoting work ow preservation.
