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)
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?
