Rationale:
Sharing scientific analyses via workflows has the potential to improve the reproducibility of research results as they allow complex tasks to be split into smaller pieces and give a visual access to the flow of data between the components of an analysis. This is particularly useful for trans-disciplinary research fields such as biodiversity and ecosystem functioning (BEF), where complex syntheses integrate data over large temporal, spatial and taxonomic scales. However, depending on the data used and the complexity of the analysis, scientific workflows can grow very complex which makes them hard to understand and reuse. Here we argue that enabling simplicity starting from the beginning of the data life cycle adhering to good practices of data management can significantly reduce the overall complexity of scientific workflows. It can simplify the processes of data inclusion, cleaning, merging and imputation. To illustrate our points we chose a typical analysis in BEF research, the aggregation of carbon pools in a forest ecosystem. We propose indicators to measure the complexity of workflow components including the data sources. We illustrate that the complexity decreases exponentially during the course of the analysis and that simple text-based measures can help to identify bottlenecks in a workflow. Taken together we argue that focusing on the simplification of data sources and workflow components will improve and accelerate data and workflow reuse and improve the reproducibility of data-driven sciences
