We have evolved Research Objects as a mechanism to preserve digital resources related to research, by providing mechanisms, formats and architecture for describing aggregated resources (hypothesis, workflow, datasets, scripts, services), their relations (is input for, explains, used by), provenance (graph was derived from dataset A, B and C) and attribution (who contributed what, and when?).
The website myExperiment is already popular for collaborating on, publishing and sharing scientific workflows, however we have found that for understanding and preserving a workflow over time, its definition is not enough, specially faced with workflow decay, services and tools that change over time. We have therefore adapted the research object model as a foundation for the myExperiment packs, allowing uploading of workflow runs, inputs, outputs and other files relevant to the workflow, relating them with annotations and integrated the Wf4Ever architecture for performing decay analysis and tracking a research object’s evolution as it and its constituent resources change over time.
