[Building Sakai] Resources and how permissions are implemented

[David Wafula Wanyonyi]

Dear team,
Please clarify something for me:
When an instructor in a site uploads a file in Resources, internally permissions are applied to the resource.
What service/methods are used to implement these permissions in the code?

Looking at the code the closest i came to understand how it works: siteId is possibly  becomes the AuthzGroupID  and  AuthzGroupService is used to apply these permissions. Not sure how this is achieved if that is the case.
And then there is BaseContentService, but this seems to delegate actual permissions implementation somewhere else ?

We are in process of implementing local custom additions  to Resources, some which include ability to share a resource between selected sites. If we get the permissions right, we are going to supply  a patch for sharing resource between sites for 2.9.x

Regards,
david
