If your cookbook requires external data consider the following in house solutions are available:
Git LFS: dedicated GitLab “data” group with Git Large File Storage
CephFS: Ceph filesharing is a POSIX-compliant filesystem (under developmnent)
S3 object storage: cloud storage that enables users to store and retrieve data using an URL (under development)
Bring your own storage: you can connect the cookbooks platform to your own storage/data repository so that data does not leave your faculty.
One should also consider the following
Can my data be openly distributed? or should the data remain private to TU Wien internally, my class room or some other group of cookbook readers?
Should readers of the cookbook access the whole dataset or is a limited subset sufficient?
Is the content of my data clearly described. For example, what are the variables and associated units?
