What about Model Data? Best Practices for Preservation and Replicability

It has become common for researchers to make their data publicly available to meet the data management and accessibility requirements of funding agencies and scientific publishers. However, many researchers face the challenge of determining what data to preserve and share and where to preserve and share those data. This can be especially challenging for those who run dynamical models, which can produce complex, voluminous data outputs, and have not considered what outputs may need to be preserved and shared as part of the project design. This manuscript presents findings from the NSF EarthCube Research Coordination Network project titled “What About Model Data? Best Practices for Preservation and Replicability” (https://modeldatarcn.github.io/). These findings suggest that if the primary goal of sharing data are to communicate knowledge, most simulation-based research projects only need to preserve and share selected model outputs along with the full simulation experiment workflow. One major result of this project has been the development of a rubric, designed to provide guidance for making decisions on what simulation output needs to be preserved and shared in trusted community repositories to achieve the goal of knowledge communication. This rubric, along with use cases for selected projects, provide scientists with guidance on data accessibility requirements in the planning process of research, allowing for more thoughtful development of data management plans and funding requests. Additionally, this rubric can be referred to by publishers for what is expected in terms of data accessibility for publication.
