Pid Cache Manager Service

This Page describes the PID cache service.

Introduction

• 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()).

Implementation

• Since PId cache service replaces the core service PIDManager, its architecture offers same interfaces.

Interface

• The PID cache service provides a REST interface:
  • GET: /<service>/<prefix>/<suffix> - resolve
  • PUT: /<service>/<prefix>/<suffix> - registration at PID system (Not implemented)
  • POST: /<service>/<prefix>/ - identifier generation and registration at PID system
  • DELETE: /<service>/<prefix>/<suffix> - delete (Not allowed)
• <service>: the url of the pid cache service (for instance: dev-pubman.mpdl.mpg.de/pidcache/handle)
• <prefix>/<suffix>: the method called:
  • /read/view : Visualization of a PID.
  • /read/search: Search of a PID.
  • /write/create: Creation of a PID.
  • /write/update: Update of a PID.
