Nordicana series D is a formatted, online data report series archived at CEN. It is produced only in
electronic form and is freely and openly accessible
to CEN researchers and to other users. Each issue
is
published in French and in English, and is indexed
via an assigned digital object identifier (DOI). An
issue may be
updated, for example with new data, as a new version number, but will retain the same DOI. Each issue
contains data sets and extensive metadata that explain the origin of the data, the format of the data,
the
history of updates via different version numbers, and the format that should be adopted to cite the data.
