File Size Limit: No specified amount; no limit on storage space per researcher

Dataset Size Limit: 300GB/dataset

Data Types and Formats Hosted: Prefers all data be submitted in non-proprietary, openly-documented formats that are preservation-friendly. Will accept other file types, if they are "community-accepted" format. Do not accept submissions with personally identifiable information.

Waiver: Creative Commons Zero (CC0) Any data submitted will be published under the CC0 license. Does not currently support any other license types, nor allow for restrictions on data access or use.

Each dataset published receives a DOI for the data submission as a whole. A suffix is added to the DOI when a data file or dataset is revised to enable version control.

Option to Share: Can be shared anonymously and securely with editors and reviewers at the subset of journals that have integrated repository into their editorial workflow. After publication, data will be publicly available immediately unless the author or journal has requested a short-term embargo prior to data release associated with a peer review.

Search: Machine Readable metadata, primarily consists of keywords and information about the associated publication. Detailed, file-associated metadata are not records and thus not searchable. Uses the DataCite metadata schema.

Download: All datasets are free to download when published. Individual file downloading, multiple API's for programmatic data and metadata access

Proprietary File Format Access: None

Data Analysis: None

$120 data publishing charge unless funded by the institution, publishers or funders. Users can download datasets free of charge once they are published.
