Repositories have some real advantages, especially when considering NSF requirements. Repositories can:
- Provide a metadata structure for you to fill in.
- Publish the data for you by giving your dataset a unique identifier (like a DOI).
- Serve as a way to backup your data and preserve it for the future.
- Make data sharing easier.
- Allow others to cite your research more often.
- Provide computational tools to assist people with using your data.
