Publishing data in a data repository promotes data reuse, verifiability, and increases research impact.
How to publish data?
The data librarians need the following information send to the Data Desk:
- The data
All data files (raw data, processed data, code etc.) used in data collection, processing, and analysis. Files that are irrelevant for verification and/or reproduction can be excluded. To ensure that data can still be read and used over a long period of time, the data needs to be available in a sustainable open format (see File formats).
- A README file
The README file is a document that accompanies the data and provides an explanation of the data, making the data understandable and reusable. Additionally, it contains metadata, i.e. data about the data (see below). A template and an explanation for making a README file is available.
- The metadata
Metadata is, besides being added to the README file (see above), used to describe data in the data repository, e.g. title, authors, keywords, etc. If not all necessary metadata is incorporated in the README file, the data librarian will contact you for extra information. Metadata, when added during deposition of data in a repository, enhances the findability of data.
If you publish data in another data repository than DANS-EASY, 4TU.ResearchData or Zenodo, the Data Desk can advise you on data file preparation, but the final deposition of the data will be done by you. When data is published in a data repository, a unique, persistent identifier (e.g. Digital Object Identifier (DOI), accession number, etc.) is assigned to it.
Costs of data publishing
There is no cost if you publish data through us at DANS-EASY, 4TU.ResearchData or Zenodo. WUR Library has agreements with DANS-EASY and 4TU.ResearchData. In the exceptional case that there is a cost (e.g. at 4TU.ResearchData there are costs when the data comprises over 100 GB) we will consult with you beforehand. The costs of storage in other data repositories will be for the research group's own account. Additionally, the Data Desk can give you advice on preparing your files for data publishing free of charge.
