While both U-M Box and Google Drive are great for maintaining a shared document repository, ownership and permissions settings (including inheritance of these settings between top-level folders and their sub-folders) works very differently in each.
Definition of Cascading Ownership & Cascading Permissions
When changes to ownership (who owns the content) or permissions (collaborators and access levels) are made to a top-level (parent) folder, those changes are automatically applied to all content within the top-level folder, including any sub-folders.
|U-M Box||Google Drive|
|Ownership and permissions settings||Can be set on any folder||Can be set on any file or folder|
|How is ownership set?||Set at the top-level (parent) folder and is automatically applied to all (child) subfolders.||Creator of each file/folder is automatically set as Owner. Ownership changes must be manually applied to each file.|
|When new content is uploaded to a subfolder, who is set as Owner?||The Owner of the top-level folder automatically becomes the owner.||The person who uploads the content is automatically the Owner.|
|Who can transfer ownership of a file/folder?||Only the current Owner||Only the current Owner|
|Changing permissions on subfolders/files||Can be changed, but cannot be more restrictive than the permissions set at top-level folder.||Can be changed as desired, regardless of the permissions set for top-level folder.|
