Work process: Data and metadata out

The catalogue entry

When you approve the reviewed description of your data, it will be published in the SND research data catalogue, and the uploaded data will receive a DOI (Digital Object Identifier). A DOI is a unique identifier for digital material which makes it easier to search for and cite data. If the data are going to be accessible by direct download from the catalogue, the datafiles and related documentation will also be made accessible through the catalogue entry. If there are any restrictions on data access, you can still choose to make related documentation, such as questionnaires, code books, technical reports,etc., accessible. 

Even after the data description has been published in the SND catalogue, you can edit the information in it. In DORIS you can edit the metadata, upload new versions of the data, or add more datasets. You can also complement the entry with new publications that build on the data material, as they are published, If you should want to remove some data material or entirely delete the catalogue entry, you can do that in DORIS, too. 

Visibility and reuse

Data which are disseminated through SND will be accessible to order or download from the SND research data catalogue, according to the conditions specified in the data deposit agreement. Incoming data are issued a DOI via DataCite, they become findable with both DataCite and Web of Science. Some research data in the SND catalogue will also become findable in the CESSDA Data Catalogue, a European research data catalogue for social science data; archaeological data can be found in the ARIADNE portal.

Research data are often reused for further research or for teaching purposes. Researchers who use existing data for their own research should always cite the person(s) who produced the material, in the same way as they would reference publications, and they are asked to notify SND about publications which use data retrieved from SND. It is good practice to only use data for the purpose stated at the time of ordering data, and to not pass on them on to other people.

Data in the SND catalogue have different levels of accessibility:

  • Data are freely accessible means that the material can be downloaded directly from the SND research data catalogue. This is the recommended level if there are no restrictions on the data.
  • Access to data is restricted means that there is some restriction which limits access to the data. The research principal may do a confidentiality assessment before the data are released.

SND keeps statistics over the number of times data are downloaded or ordered. If you want to view these statistics, please contact In time, statistics will become accessible after you’ve logged in to the system.
