PID Cache Manager Service
Status[edit]
Work in Progress (version 0.1.0 in test).
Description[edit]
- The role of the PID cache service is to avoid unavailability of the GWDG PID Handle Service.
- The PID cache service is used as alternative to the PIDManager service offered by eSciDoc core infrastructure.
- The PID cache service holds pre-created PIDs which are assigned to an eSciDoc content resource by calling the Object Handler methods (assignObjectPid() and assignVersionPid()).
