Q. Is a plan for Data Management required if my project is not expected to generate data or samples?
Yes, in many cases funding agencies require a data management plan, even if you don't expect to generate data. It is acceptable to state in the Data Management Plan that the project is not anticipated to generate data or samples that require management and/or sharing, but you should explain why this is the case. Keep in mind that there are a variety of types of data (beyond numerical datasets) that you might want to manage over the lifespan of the project.
