[GRAAP-WG] Penalties

[Bastian Koller]

  Hi,

just a quick answer to (ii)

Having now dealt with several approaches, I think we have to deal with 
two different kinds of monitoring.

a) is the monitoring, which is done inside a Service Provider and which 
allows to monitor all kind of data (as needed)
b) is a monitoring, which a Service Provider potentially offers to a 
Customer or to some sort of Monitoring Broker (which acts on behalf of 
the Customer, may be trusted). We assume, that the monitored data here 
will need to be "anonymized" or "filtered" to ensure the confidentiality 
of the SPs insides, but at the same time allow the Customer to see what 
happens.
Generally this does of course not remove the potential of "faking" 
monitoring data to the outsider to give him/her the feeling that 
everything is fine. So thats a matter of trust.

In all cases, the monitored values need to be evaluated somehow, which 
may lead to some sort of event driven logging and based on these logged 
occurances, penalties may be charged in a global accounting/billing process.

Just my two cents

Bastian

Another option we are looking at is integrating a reputation system that builds profiles of each participant in the system based on the number of successful or violated agreements. These are very interesting options, but we have not yet fully developed them.
