Determine if your research data should be saved by answering a few questions:
Is there an obligation to preserve the research data so that it can be reused and repurposed, e.g. imposed by research funding bodies, academic publishers or others.
Are there valid reasons to preserve the research data so that it can be reused and repurposed for research purposes? Think about from perspective of your research discipline and also from other research disciplines.
Are the data important for the history of the discipline?
How cost effective is it to deposit the data, i.e. expense of repeating research vs. depositing.
How unique are the data? Can the research be repeated? Does the data contain non-repeatable observations?
Is the technology (hardware, software) used to acquire or process the data unique, constantly upgrading or is in the process of being replaced by newer technology? Is the repository willing to accommodate these changes?
Are all the components of the research data available to ensure it can be reused; documentation, metadata, appropriate versions of data?
If the data resulted from collaborative work, do you have the appropriate permissions?
