Subject: Re: [wsdm] Proposal Definitions on Requirements Docs

There are always too many overloaded words, like "model", but I think this does a good job by specifying what representation would be done. Plus it aligns well with the WSDM Charter. Note that the current MOWS Requirements documentation calls for a UML representation specifically. [OVERALL.2]. Perhaps that should be included in the definition. > > Management Using Web services: > Specifies how to to use Web services architecture and technology to > manage distributed resources including defining how to represent the > manageability of manageable resources in WSDL. > This includes defining: > – Generic manageability schemas and interfaces > – Interfaces for directly manageable Web services > – Interfaces that integrate existing managed resources into a Web > services environment Hmmm. What about some of the words currently in the MUWS Requirements document? Specifies how to to use Web services architecture and technology to manage distributed resources, addressing management of any type of manageable resource, as long as the resource has a Web Services manageability interface, provided by the manageable resource or by another entity on behalf of the manageable resource. Includes defining how to represent the manageability interface using WSDL. This includes defining: - The components of the manageability interface, including operations, attributes, and event notifications. - A core set of manageability interface components, by management category (Monitoring, Controlling, Performance, etc.) - Additional sets of manageability interface components that can be added as needed - Methods for extending what has been specified - Examples of mapping an existing information model for a managed resource to a Web Services manageability interface. > > Feedback on definitions and inclusion into Requirements drafts appreciated. > > Heather Kreger > STSM, Web Services Lead Architect for SWG Emerging Technologies > Author of "Java and JMX: Building Manageable Systems" > kreger@us.ibm.com > 919-543-3211 (t/l 441) cell:919-496-9572 -- John DeCarlo, The MITRE Corporation, My Views Are My Own email: jdecarlo@mitre.org voice: 703-883-7116 fax: 703-883-3383 DISA cube: 703-882-0593
