Beyond "Yes or No" - Extending Access Control in Groupware with Awareness and Negotiation

We present three scenarios concerning access to documents in three real world fields of application, which have in common that they are very difficult to support with classical anticipative access control systems. We show, how - based on a highly configurable notification and negotiation service, which is tightly integrated with a classical access control system - the common permission and denial options can be extended with awareness and negotiation and how this approach supports the three initial access scenarios. We also introduce our implementation of the notification and negotiation service in the PoliTeam project.
