ODISSEI-CBS Data Storage

Projects utilising microdata sometimes result in large files that are of interest to other projects. However, storing the data derived from those projects leads to significant costs for researchers developing those files, limiting their reuse potential. Researchers can now store the files derived from the microdata projects in the ODISSEI-CBS Data Storage, which reduces their storage costs while making valuable datasets accessible to others.

ODISSEI membership is not a condition for using the facility, the data should, however, be of great value to the ODISSEI research community.

From 1 December 2024, 20TB will be available for a period of six months. In April or May 2025, this procedure will be reviewed between CBS and ODISSEI and it will be determined whether the facility will continue and in what form.

What are the requirements?

  • The file made available by its creator was created using CBS microdata only.
  • It is a large file, which means there is a hefty cost to store the file within the project environment.
  • All other conditions as implied by the CBS law apply
  • The file is valuable to other users.
  • The script used to create the files and the metadata describing them must be prepared by the creator, be of sufficient quality, and be suitable for public availability. 
  • The link to the script and the metadata will be published in the ODISSEI Code Library and Portal
  • CBS will place the metadata in the RA environment alongside the file. 
  • The creator of the file takes responsibility for answering any questions about the file. 

What are the steps?

  1. Fill in the form to request the ODISSEI-CBS Data Storage. In your H drive, create a folder called ‘Data Storage’, place the filled-in form there, and inform your CBS microdata advisor of this
  2. After CBS and ODISSEI agree on using the facility to store your dataset, you can place the data file, metadata file and scripts in H:/Data Storage. The metadata template will be made available in that folder. CBS will move the data to the Data Storage. 
  3. CBS will perform an output check for metadata and scripts.
  4. Publish the code in a code registry of your choice (e.g., Zenodo, Open Science Framework – OSF, etc.) and include the link to it in the metadata form.
  5. Send the metadata form to ODISSEI Scientific Manager Kasia Karpinska, so that the ODISSEI Coordination Team can publish the metadata via the ODISSEI Portal to make your dataset findable, and add the link to the code via the ODISSEI Code Library.

If you have questions about the publication of the metadata or code, you can reach out to Angelica Maineri, ODISSEI Data Manager.
