For definitions of the five criteria for Yes/No response used in the query to repositories, please see below:

1. Current NIH funding support: Is the repository currently supported by NIH (whether owned and operated by NIH, like NDAR, or funded extramurally through a grant, cooperative agreement, contract, or OTA)?
2. Open data submission: The repository accepts data from a broad set of investigators. Ideally, any investigator with relevant data can submit data, but narrower sets of investigators are permissible, e.g., any investigator funded by a particular NIH IC. What would not meet this criterion is a repository that accepts data only from a particular project team or small, closed group of funded investigators.
3. Open data access: The repository makes data accessible for cost-free re-use by other investigators. This criterion can be met even if an investigator must request access to the data and have the access request approved by a data access committee. What would not meet this criterion is a repository that makes data available only to other investigators who are part of the original research team that collected the data.
4. Open time frame for data deposit: The repository accepts data from collected at any point in time after it was established. What would not meet this criterion is a data repository that accepts data only from one or more projects that have a defined beginning and end, i.e., no new data is added after the project ends.
5. Sustained support: NIH (or another sponsoring organization) expects to support the data repository for the foreseeable future. What would not meet this criterion is a repository that was established for a time-limited period.
