Keynote: Computational Reproducibility vs. Transparency: Is It FAIR Enough?
The “reproducibility crisis” has resulted in much interest in methods and tools to improve computational reproducibility. FAIR data principles (data should be findable, accessible, interoperable, and reusable) are also being adapted and evolved to apply to other artifacts, notably computational analyses (scientific workflows, Jupyter notebooks, etc.). The current focus on computational reproducibility of scripts and other computational workflows sometimes overshadows a somewhat neglected and arguably more important issue: transparency of data analysis, including data wrangling and cleaning. In this talk I will ask the question: What information is gained by conducting a reproducibility experiment? This leads to a simple model (PRIMAD) that aims to answer this question by sorting out different scenarios. Using data cleaning recipes from OpenRefine as an example, I will present some approaches to improve transparency and reusability of such recipes via workflow analysis. Finally, I will present some features of Whole-Tale, a computational platform for reproducible and transparent computational experiments.
