Along with many peer-review publications, a Data Collection is now required or recommends. If the data used in the publication is not available in an existing archive, you can create a Data Collection related to the publication to be hosted at the UND Data Commons, see http://commons.und.edu. The contact person is Zeineb Yousif to work with for creating a new Data Collection.
We have been using a similar template (datacollectiontemplates.tar.gz) that you can adjust for your type of research. The meta data in the DataCollection_GappEtAl_JAS_2020417.txt template file was used for the Data Collection 16 - DOI 10.31356/data016, which was referenced in the published paper. Along the meta data, we submit a compress archive file containing all the data files, in one single file, which has a limit of 10 GB that should be sufficient for most needs. Hence, in summary when we (really have student do all this) do a new Data Collection, we use the template and fill out the required meta data, put all files into a compressed archived file (zip file format would work) and send email to Zeineb Yousif, likely file too large to email so give a share link of where to get the data.
