  Due to the global violence of the novel coronavirus, various industries have
been affected and the breakdown between systems has been apparent. To
understand and overcome the phenomenon related to this unprecedented crisis
caused by the coronavirus infectious disease (COVID-19), the importance of data
exchange and sharing across fields has gained social attention. In this study,
we use the interactive platform called treasuring every encounter of data
affairs (TEEDA) to externalize data requests from data users, which is a tool
to exchange not only the information on data that can be provided but also the
call for data, what data users want and for what purpose. Further, we analyze
the characteristics of missing data in the corona-related confusion stemming
from both the data requests and the providable data obtained in the workshop.
We also create three scenarios for the data design of unobserved events
focusing on variables.
