This is the Prefix Information Service, which can be used to get an overview of the integrity of the PID
infrastructures and the B2HANDLE services provided by DICE. The B2HANDLE services,
and particularly the Handle System, do not provide any easy way that would
allow users to get more useful information about their services, like which servers are responsible for a prefix,
or how many mirrors are registered for a particular PID. Such an overview is important for both PID service
providers, as well as for service users. In case of the service providers, they need a unified view on the status
of the integrity of the PIDs provided and thus, all components and services of its PID infrastructure. From the
end user point of view, a descriptive easily understandable overview is needed. We created the Prefix Information
Service to fill this gap.
