Here you find frequently asked questions about data and making data accessible via SND.


What is research data?

Research data are any data that are used for scientific analysis, irrespective of research field.

What is metadata?

Metadata is structured information that describes and classifies digital information, in other words ”data about data”. Metadata in SND’s research data catalogue make it easier to find and understand the specific properties of the data material, and information about collection methodology.

Why should I share the project’s data?

For several reasons. There is a growing demand that publicly funded research shall be open, and scientific journals are demanding that their authors make the data that their analyses are based on accessible. Sharing research data benefit research as well as society. It increases transparency, enables new research, innovations, and use of data in fields beyond the research community. On an individual level, researchers can feel motivated by having their studies and data sets cited and made visible.

Who can deposit data with SND?

Data can be deposited by anyone who represents a research principal, i.e. a governmental authority or a natural or legal person responsible for the research conducted in their remit. It is normally researchers employed in a university or higher learning institution who take the initiative for and manage the data deposit. The researcher then acts as a representative for their principal.

Is there a fee for describing and depositing data with SND?

No, it is completely free of charge.

What happens to the information that I enter in the form?

Metadata and data deposited via SND’s data description form are made accessible in our national research data catalogue as a catalogue entry. Before the entry can be displayed in the catalogue, the information is reviewed and the primary researcher always has an opportunity to read through and update their data description. The review is not an assessment of the scientific quality of the research data, but on the documentation of the data and data collection.

How do I submit data to SND?

Data can be uploaded directly to SND in the data description form. At present, you can only upload files that are 500MB or less. If your data files are larger, you can contact us on ur@snd.gu.se for advice on the best way to deposit the data material.

What is the best file format for uploading data in SND’s data description form?

SND has evaluated a number of different formats that we consider suitable for the management, long-term storage and accessibility of research data. These may change over time according to technical developments. Read more about recommended file formats here.

Can SND accept data that contain personal data?

At present, SND can only accept data with personal information from researchers at the University of Gothenburg. Data from other universities or research institutions must be fully anonymised (de-identified). As universities and research institutions establish DAU and local storage solutions, this limitation will gradually not apply for their locally stored data. Until then, you can still describe research material in SND’s catalogue without submitting the actual data.

What is anonymised data?

Anonymised data are data that have been de-identified, so that it is no longer possible to identify a living individual from the data. This means that code and encryption keys have been destroyed and that individuals cannot be reverse identified from the data. Anonymised data are exempt from the General Data Protection Regulation and complementary legislation.

Does SND assume ownership of deposited data?

No, the research principal always retains full ownership of the data that are described and deposited with SND. The research principle is a governmental authority or a natural or legal person responsible for the research conducted in their remit.

Can I edit a published data description?

Yes, but at present it has to be done by SND staff. Contact ur@snd.gu.se with the changes and additions that you want to make. During 2020, SND will launch a system where researchers and DAU staff can edit catalogue entries.

Can I update the study description with later publications?

Yes. Contact ur@snd.gu.se and let us know what publications should be added to your description. During 2020, SND will launch a system where researchers and DAU staff can edit catalogue entries.

Can I describe research data from an active project with SND?

Yes, you can describe current research and make it visible with SND.

What happens if a study’s principal investigator goes into retirement or dies?

A principal investigator who is no longer active due to retirement or death can still be the principal investigator of the study. If a principal investigator who is no longer active was also the contact person for the study, you can appoint a new contact after consent from the principal.

Can I take back data that I have deposited with SND?

Yes, the data owner can always have their deposited data back from SND.

How is data material ordered from SND used?

Research data from SND’s catalogue are often re-used for further research or for teaching purposes, e.g. in student essays or theses on bachelor or master level.

Can I see how many views the project’s data have had since they were made accessible in the catalogue?

SND keeps statistics over the data sets that have been published in the research data catalogue. If you want to know how many times that a published material has been ordered or downloaded you can send a request to ur@snd.gu.se. These statistics can be useful if you want to argue for the value of your scientific production. Over time, the statistics over downloads and orders will be accessible via the login function.

What is a DOI?

A DOI (Digital Object Identifier) is a type of persistent identifier (PID) that is issued to every dataset that is described in SND’s research data catalogue. A DOI links the data to a persistent description that remains the same even if the data files are moved. The purpose of a persistent identifier is to ensure correct citation of research data and to show which version of the data that has been used. Scientific journals often require that in order to publish material based on datasets, the datasets have to be accessible and have a PID/DOI. Read more about DOI here.

What does it mean that a data repository is certified?

A certified data repository (a Trusted Digital Repository, TDR) follows certain recommended methods and standards for trustworthy data management. These methods and standards also enable the FAIR data principles. SND is the only Swedish repository with a certification.
