KN-IPCMS The KoNstanz Inter-Process Communication Management System (KN-
IPCMS) is a platform-independent, message-oriented communication protocol which is
used to communicate between an application and the BGP-MS shell system. In figure
2 we have three types of communication.
1. If the application wants to tell the shell system about an observed believe or goal
of a user, it can send an bgp-ms-tell message to the shell.
2. The message type d-act is used to tell the shell system about an action that a
user has performed in the application.
3. Assumptions about a user are an important information for an application, so the
application can request such an assumption with a bgp-ms-ask message send to
the shell system, and the BGP-MS can send the answer in an bgp-ms-answer
message to the application.
Below the arrows we can see the messages which are described in the belief, goal, plan
language (BGPL). As we take a look at the d-act message, we can interprete it, that the
print command is executed on the user documentation. If you want more information
about other types of messages you will find it in [KP95].
