Résumé
Only few organizations worldwide can ensure the long term storage and access for theirnumeric resources. Indeed this requires a replication of data in multiple sites within secured datacenters. Consequently, even in scientific organizations, the rate of data loss is important and thissituation is no longer accepted by funding agencies which are requiring research projects toimplement data management plans to ensure that the funded data and resulting information andknowledge will not be lost. In addition, beyond economical considerations and for obvious ethicalreasons, data have to be made accessible along with publications to enable the review and thereproducibility of the scientific work. To be found once published, resources also have to bedescribed with standardized discovery metadata which foster interoperability on the Web. For years,multiple data repositories have offered free services for the long term storage of any kind ofnumerical resource. These repositories also assign unique identifiers (Digital Object Identifier; DOI)which foster their reuse and citation worldwide by complying with standardized metadata. Inpractice, scientists are already used to getting DOIs assigned to their articles by scientific journals butstill few of them are assigning DOIs to other products like their data, code or reports. In 2019, a firstwork has been driven in collaboration with IOTC to start assigning DOIs to a selection of IOTC reports.In this paper we present a summary of the past work results and make some recommendations toupdate it by assigning new DOIs to other kinds of IOTC resources (e.g., datasets, working papers).
