* Group <code>wg-datasharing</code> (or any other name you prefer) must be created in CCDB and you must be assigned ownership of this group. This allows you to add or remove members of the group in [[https://ccdb.computecanada.ca CCDB]]. | |||
* The directory, <code>/home/smithj/projects/def-smithj/shared_data</code> in our example, must be owned by you. | |||
* Since the data sharing group (<code>wg-datasharing</code> in this example) is not necessarily the owner of the directory you would like to share (<code>shared_data</code> in this example), all parent directories in its path should allow public entry, that is, execute permission. They do not need to have public read permission, unless you decide to allow it. | |||

# Send email to [mailto:support@computecanada.ca support@computecanada.ca] requesting creation of data sharing group, indicate name of the group you would like to have and that you should be the owner. | |||
# When you receive confirmation from Compute Canada Support that the group has been created, go to [https://ccdb.computecanada.ca/services/ ccdb.computecanada.ca/services/] and access it: | |||
