Is it possible to have collections of collections

[William Lewis]

Hi,

 

We are beginning to roll out globus for data distribution within our facility. We have approximately 100 instruments in our facility, and about 60% of them produce data that users take away and process etc for their studies. Currently we sync the data from the instrument PCs to a number of shared cloud research drives, which we give users access to. Currently we have no way of restricting access to different folders within the shared drives, so all users can see all data on a shared drive.

 

We are progressively having Globus rolled out and are intending to replace our current systems with access via globus. I intend to programmatically create Guest collections for each user on each instrument folder. However, many users access multiple of our instruments, and in an ideal world I would combine for each user their multiple guest collections into a single guest collection for them to access – i.e. a guest collection of guest collections. Is this possible?

 

There would be other ways to attack this, but this would involve the least disruption to our current setup.

 

Thanks in advance!

Hi William,

At this time, there is no way to create an overlay of multiple guest collections, as you describe. To aid in discovery of a set of collections by a user, the metadata on the collection you create will be critical (e.g. keywords), and the collection listing interface allows filtering for collections that have been shared with a user.

However, have you considered the option of pre-creating guest collection(s), and programmatically managing permissions on folders in the guest collection for each user?  

For example, you can create a single guest collection for all of this data, and programmatically manage (grant and revoke) permissions at folder level for your users. When a user lists the collection, they will only see the folders that they have access to. This does assume that there is a single mapped collection from which all data is accessible, and data is organized for user permissions on subfolders to work.

Alternatively, you can create a guest collection for each instrument, and set permissions for users for subset of data on each guest collection. This does not meet your exact ask of single guest collection that a user has to access, but it  allows for more permanent collections per instrument, and discovery/bookmarking is easier.
