Context

• WSDM is an early adopter of WSRF
• Standardized on WS-RP for accessing properties
• Uses WS-Addressing for manageability endpoints
• WSDM had requirements is was planning to meet on
  its own but that are now best passed to WSRF (and
  WSN)

3
Already communicated requirements 1/2

• WSRF to define a topic for people to register for
  notification on value change affecting any
  property (or at least any property for which
  notification is available) without having to
  register for each property.
• This is now a WSRF issue (55)

4
Already communicated requirements 2/2

• Ability to query list of available properties at
  runtime
• This is part of WSRF issue 9
• Discovery of EPR when you have the WSDL (issue
  47)
• Description of issue still not finalized by WSDM
• Completeness of EPR (issue 46)
• Retrieve the complete WSDL, know which
  service/port to use

From WSDM requirements 2/3

• Discovery of manageable resources through Web
  services discovery mechanisms
• Access to aggregations of manageable resources,
  including invoking operations on several
  resources in one operation

From WSDM requirements 3/3

• Variety of resource types (logical/physical,
  long-lived/transient, etc)
• Discovery of relationships
• Modular approach to capabilities. Allows
  discovery of manageability capabilities.
• Versioning of WS-Resource endpoints
• Access to attributes (read and/or write)
• Meta-data introspectable at design time and run
  time

Timeline

• WSDM 1.0 targeted for Oct/Nov 2004.
• Doesnt necessarily require final WSRF specs, but
  needs answer to these questions
