PID API here

A webservice for generating a PID will be provided.

The API will be trivially simple: A call to the given method will give the next available API. Optionally, a prefix may be given that should be part of the PID.

The call should never fail.

Implementation note: Due to a length restriction of 64 characters for Fedora PIDs, any prefix longer than approx 50 characters will be shortened, to ensure space for adding a unique part to the PID.
