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 PIDManager service hosted at the GWDG [1].
• The PID cache service overrides the PIDManager service for the eSciDoc solutions.
• The PID cache service owned predefined PID which are assigned to eSciDoc Object by calling the Object Handler methods (assignObjectPid() and assignVersionPid()).

Implementation

• Since the role of the PId cache service is to override the PIDManager, its architecture intends to simulate the PIDManager.

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)
