I recently submitted a paper to a conference together with some colleagues. The paper was accepted with some helpful review comments. Specifically, one reviewer suggested to make the underlying data available to the public. In my case the data is comprised of a network derived from openstreetmap data.
My questions are the following:
Where can I persistently store the data (totaling ~60 MB)?
Can I get a DOI for the data itself?
What about copyright notices (attribution seems necessary)?
