On 23 July, Anja Perry and Sebastian Netscher presented their poster Measuring the Costs of Research Data Management at the 10th ESRA Conference 2021. In this poster, the two authors explain that there has been little work to date on calculating the costs of research data management. This is mainly due to the fact that costs for research data management are generally difficult to calculate, as they can vary greatly from project to project. The authors then analysed four cost-driving variables by evaluating them empirically. Based on these analyses, modules within the DDPs (Domain Data Protocols) will then be designed to support users in calculating the costs of research data management within their own research project.
