WSDM MUWS requirementsfor WSRF William Vambenepe July 28th 2004
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)
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)
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 1/x WSDM MUWS requirements doc: http://www.oasis-open.org/apps/org/workgroup/wsdm/download.php/6185/WSDM-MUWS-Req-committee-draft-1.0-20031002.pdf
From WSDM requirements 2/x • “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/x • 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
Timeline • WSDM 1.0 targeted for Oct/Nov 2004. • Doesn’t necessarily require final WSRF specs, but needs answer to these questions
