This document discusses the challenges of sharing large-scale and sensitive data and outlines approaches to address them. It describes how data sharing needs to continue supporting discovery, citation, access and reuse of data as datasets increase in size from GBs to TBs and PBs. Current collaborations are working on techniques like integrating large datasets with the Dataverse platform, deploying Dataverse on cloud computing resources, and using the DataTags system to enable controlled sharing of sensitive data while preserving privacy.
