Annotations on access controls in wikis

Abstract

In this paper, we propose a system which allows users to attach annotations to access controls in wikis. When managing documents in wikis, they need to have access controls for preventing the documents from being accessed inappropriately. The access controls are usually modified dynamically according to changes of needs on wiki documents. It is generally difficult to keep access controls consistent beyond the modifications. Annotations are introduced in this paper for this problem. We focus on a situation where a set of access controls that was supposed to be stable is recovered using backups, discuss contradictions between access controls potentially occurred in the situation, and propose what kind of annotations will help solve the contradictions.
