Library permissions management

[elv-serban]

OBJECTIVE

Create a fabric browser group permissions flow that works correctly for library operations.

BACKGROUD

There are two sets of access controls for libraries:

1. Library specific permissions controlling what can be done with content inside the library

• accessor - can list contents in the library
• contributor - can create new content in the library
• reviewer - this enables a custom review flow that we don't want at all exposed

2. Regular object permissions

• see - can view the public areas of the library object (metadata)
• access - can view entire library object (private and public metadata, encrypted parts, etc)
• edit - can modify the library object
  • this is also required in order to delete other people's objects in the library! (little known fact ...)

CURRENT SITUATION

We expose the 3 permissions that are library specific.

• we really don't want to expose 'review' - this functionality should be removed (and at a minimum hidden)

We don't expose the regular object permissions see/access/edit - these can only be accessed through the contract methods directly.

PROPOSAL

Theoretically we have 6 permissions to configure:

• library level 'accessor'
• library level 'contributor'
• library level 'reviewer'
• object level see
• object level access
• object level edit

But only some of them are useful:

• library level 'accessor' - this is useful and we should keep it
• library level 'contributor' - this is useful and we should keep it. It implies accessor so we shouldn't have both contributor and accessor
• library level 'reviewer' - this is bad and we want to hide it
• object level see - this is not useful - it is implied by library 'accessor'
• object level access - this is not useful - it is implied by library 'accessor'
• object level edit - this is useful and we should keep it

So my proposal is to expose the following:

PROPOSAL

Instead of the current:

Selector of one of the following 3 options (radio buttons or picker, something like that)

1. "View"

• this provides library-level 'access'
  • same as we do in libraries "Manage Group Permissions" and select "Access"
• description "List content objects in the library. View library metadata'

2. "Contribute"

• this provides library-level 'contributor'
  • same as we do in libraries "Manage Group Permissions" and select "Contribute"
• description "List and create new content objects in the library. View library metadata"

3. "Manage"

• this provides the object level 'edit'
  • same as we do in a regular content object "Manage Group Permissions" and select "Manage"
• description "List, create and delete content objects in the library. Edit library metadata"

Discussion with Marc and Zenia.

Marc's analysis based on reviewing the code:
Pre V3: Only the owner of an object can delete it.
V3: The owner cannot delete the object unless he is also a library manager of that library, a non owner manager can also delete the object.

Demo is on V3
Prod is on V2
