An open access repository stores digital objects and makes them available, with their descriptive documentation, and downloadable. It’s accessible and interoperable through a OAI-PMH protocol and it deploys a long-term archiving policy.  

Open access repositories can be divided into:

Criteria for the selection of a data repository

  • Is long-term preservation guaranteed or not? Look for the condition of long term preservation
  • Does the repository assign/include PIDs? For example DOI or handle (dataset) or ORCID (researchers) and ROR (institutions).
  • Where is the location of the repository? Important for the data protection law.
  • Are there any storage costs involved and what are they? Costs should be taken into consideration in your Data management plan.
  • Does the repository have a clear policy and easy findable terms and conditions? Important for granting access and reuse
  • Is there descriptive metadata accompanying the datasets? Metadata make data findable, interoperable and understandable
  • What is the default license? For example in UNIMI Dataverse the default license is CC 0 but other licenses are allowed
  • Is the repository certified? For example the Coretrustseal

Data Journals

It makes sense to consider to publish your dataset in a peer-reviewed data journal. This will improve the transparency of the adopted methods and results.
