* The key/value pairs included in the share info depend on the function originally called:
* If called by getItem(s)Shared: id, item_type, item, item_source, share_type, share_with, permissions, stime, file_source
* If called by getItem(s)SharedWith: id, item_type, item, item_source, item_target, share_type, share_with, permissions, stime, file_source, file_target
* This function allows the backend to control the output of shared items with custom formats.
* It is only called through calls to the public getItem(s)Shared(With) functions.
