Problem Statement

  • Existing research processes span multiple systems
  • Integrated into local IT infrastructure of researchers
  • Very heterogeneous (IT) system landscape
  • Legacy systems often not intended for integration

  • Centralized Identity Management

 Different Models: pre provisioning vs. on demand distribution

  • User Identity and current Session

 covey sessions and user information  between systems and steps of the process

  • Protect and govern personal data

 Enforce data minimalism  Protect personal data

  • Store small amounts of data

 Settings  Cache

  • Reduce impact on “non-interactive” systems
  • Allow different levels of storage

 Per process (user shared)  Per user (process shared)  Per process and user (private)

  • Specific for backend systems

 Legacy systems require in depth technical knowledge  Modern systems often provide interfaces

  • Process Independent

 Allow re-use of backend systems  May allow administrative access

  • Change processes base on systems

Tier 2. Technology Dependent Backend Interfaces Enable access to technologies

  • Expose standardized protocols
  • Enforce access in users context
  • Common semantics for process entities
  • Change processes orient towards software

Conclusion of Case Study

  • simpleArchive is available to selected researchers at RWTH Aachen since Q2 2016
  • Implementation reuses existing systems and APIs

 gigaMove  Backup-Portal  OAuth2 Service  REST Application Proxy

  • Even a simple process need policies

 How long is the data actually stored?  Who can restore the data?  Can archives be transferred?  Can archives be deleted?
