DataONE is an NSF supported initiative around data sharing. It's focus is on infrastructure, research and education in data sharing. It has several useful tools including: Best Practices Database - search or browse to best practices topics e.g. Create and document a data backup policy. Educational Module - An indepth step by step module about data management e.g. Data Quality Control and Assurance.
Warning: These excellent resources are from the UK, so information around data policies will be different from those in the US.
This tool guides grant applicants through the process of creating a data management plan. Faculty and students can log into this tool using their NYU Home account. Personal accounts can also be created for those without a NYU NetID.
A data repository for the basic and applied sciences, Dryad provides a platform for data related to a publication. Supports smaller datasets, and is governed by a consortium of journals that promote data archiving.
This page shows a list of NIH-supported data repositories that accept submissions of appropriate data from NIH-funded investigators. The list also includes resources that aggregate information about biomedical data and information sharing systems.
