Data Repositories

Digital Object Identifiers (DOI) are unique strings of characters assigned to different kinds of research objects (articles, data, projects, files, etc.) that are made available in a digital environment. They are an important portion of metadata and, as a type of persistent identifier. DOI is also needed for journal Data Availability Statements (DAS). To obtain a DOI for data, you can use the following two ways:

1. Depositing Data with Repositories:

• Dryad assigns DOIs to all published datasets. 
• Figshare will provide a DOI for any deposited work, including datasets. 
• Zenodo also provides DOIs for any kind of research output, including datasets. 
• Other Repositories: Many other data repositories offer DOI assignment for deposited data. 

2. Using DOI Registration Services: 

You can register for a DOI from a DOI registration agency (RA) service, such as those listed on doi.org/the-community/existing-registration-agencies.
