Creating Federated Data Stores For The LHC

Programme Scientifique

The points of discussion in this meeting are the following:

• Federated Data access models:
  • Mechanisms:
    • Copy on demand.
    • Real time access.
    • Partial caching.
  • Pros and cons to each mechanism:
    • Requirements to make each model work well.
  • Firewalls.
• Federated Name Space:
  • Providing a uniform global logical name space:
    • Challenges and solutions.
• Federated Monitoring:
  • Metrics:
    • Necessary information.
    • Desired information.
    • Level of detail.
  • Visualization:
    • Architectures.
  • Incorporating local information:
    • Mechanisms.
    • Useful metrics.
• Federated Security:
  • Requirements for different access modes:
    • Client/Server vs Server/Server access.
  • Emerging mechanisms:
    • DOE’s InCommon Federated Trust Model, Shibboleth, etc.
• Federated Support Structure.
