Default URL when creating datasets

[Jolanda5]

When creating a knossos dataset using initialize_from_array (which calls initialize), the URL parameter gets written using an absolute local path. This leads to me being able to open the created dataset in knossos but my coworkers can't. The datasets are located on a shared drive.
Is there a specific reason why absolute paths are used?
Can we change/enhance that behaviour so I can share non-streamed datasets with my coworkers?
