Accepteerde file formats The choice of file format is of essential importance in order to ensure that the research data will remain usable and ‘legible’ in the future. 4TU.ResearchData therefore strongly encourages the use of standard, exchangeable or open file formats. For the preferred formats, 4TU.ResearchData guarantees that the research data will remain accessible and that they will be migrated or converted if necessary.

4TU.ResearchData provides two levels of support for file formats:Full preservation:
•All reasonable measures will be taken to ensure that the file formats remain legible and usable. These measures include migration, normalisation and conversion.
•Bit-level preservation: Access to the data object will be offered in the file format that was originally provided.
Maximum size of deposits Free until 10 Gb (in 2018), beyond in consultation. More than 1 Tb can be a problem.
Version management Yes
Quality control 4TU.ResearchData will check the data before publishing them to make sure all files can be opened, are in a sustainable preferred format and an explanation of the data is available to make re-use possible. Suggestions are made for additional metadata in order to increase the discoverability of your data. We do not check or judge the quality of the data. http://researchdata.4tu.nl/en/publishing-research/uploading-data/
