  1. OASIS Web Services Distributed Management Technical Committee Dec 2,3 Face to Face #4 Dell Austin, TX

  2. Agenda Dec 2nd • 8:30-12 MUWS: Architecture (John DeCarlo to coordinate), • 1. Context - Heather. • 2. Concepts - Igor. • 3. Logical Architecture - Igor. • 4. Implementation Architecture – Igor. • Start next subgroup for Manageability Building Blocks (Heather) • 12-12:30 Lunch • 12:30-1:30 Glossary (Karl Schopmeyer) • 1:30-5:30 MUWS: Web services Platform (Homayoun to coordinate)

  3. Agenda Dec 3rd • 8:30-11:30 MOWS: Web Services Model (Igor Sedukhin) • 11:30-12 DCML (Igor Sedukhin) • 12-12:30 Lunch • 12:30-2:30 Specification phasing • 2:30-5:30 Action Items/Planning/Laisons/Wrapup/Next F2F

  4. Remembering the last F2F…Oct F2F Timelines & Milestones • MUWS Arch • Nov 1 – first draft • Dec 1 - done • MUWS WS Plat • Nov 1 – identify req’d, recommend approach • Dec 1 – draft req’ds for first submission • Manageability • Nov 1 - start • Dec 1 – scope , State model, event fmt, umls for base manageability model • MOWs Model • Nov 1 first draft • Dec 1 models

  5. MUWS Spec Outline • 1. Meta Model • 2. Architecture – extensive in sep doc; brief in this doc; manager motivation, expose mgbility ifc about resource • 3. WS Platform Requirements • identify platform functionality required, which specs should be used, the interim solution if there are not existing specs, or pointer to future • bubbles on chart1 • i.e. ID, version, notification, collection, relationship, registry, policy , security, addressing, etc. • 4. Manageability • identify functionality/capabilities required to support describing and using manageability of resources using Web services • bubbles on chart2 + • i.e. Resource state model, event format, configuration, metrics, operations, identity, version, change control, basic relationships for manageability • 5. Discovery and Introspection • finding manageable resources • introspecting manageability interfaces • 6. Defining a manageability interface for a manageable resource using this specification • how to mix in functions in section 3 and 4 – probably normative • profiles of manageable resources? ( configurable? monitorable? ) not sure if normative • how to satisfy some of the main usage scenarios? – sep doc • Appendix for full schemas, namespaces, types • ? How do we represent in each section with text do we exhibit: schema, example fragment instances (not normative for understanding), and/or other representation of allowable syntax (like in ws-s docs). We have a multiple ifcs issue for examples. Pseudo may help here. Schema defines syntax but is not required as long as syntax is correct ( a convention from soap )

  6. MUWS Spec Tasks/Editors 1. Meta Model 2. Architecture 3. WS Platform Requirements 4. Manageability 5. Discovery and Introspection 6. Defining a manageability interface for a manageable resource using this specification Tasks: • Meta/Architecture task – UArch – Zulah lead, Heather, Winston, Igor, GeoffB. Richard N., KarlS., Andrea, Rajiv • WSPlatform requirements/recommendations task – WilliamV. lead, Heather, Igor, Homm., AndreasD., TomS. Editors – John DeCarlo, WilliamV., PaulL., Heather

  7. MUWS Architecture • Conceptual model – picture • Logical model • Role & Artifacts definition • Responsibilities • Capabilities • Interaction patterns • Manageability Info meta model • Distribution arch

  8. 3. WS Platform Requirements Section Identify platform functionality required (in addition to WS-I basic profile), which specs should be used, the interim solution if there are not existing specs, or pointer to future (source bubbles2 chart) • Identification – Unique Id for svcs • Version – version of service, in URIs today, w3c tab? sufficient? • Attributes • Metadata • Addressing – like ws-addressing and gsr/gsh • Security - +bootstrap security mode? • Flow • Policy – may not be reqd for vers 1 • Negotiation • Notification Mechanism • Registration/discovery • Collection • Name Resolution • Relation • Relationship Service? • Logging • Policy Decision Point/Policy Enforcement Point • Lifecycle Support

  9. 4. Manageability Identify functionality/capabilities required to support describing and using manageability of resources using Web services (bubbles on chart2 +) • Properties, operations, events & metadata • Identity • Version • Change control • Metrics • Configuration • State • Relationships • Resource State Model – description of states/transitions • Basic relationships for manageability (metadata?) • Event Format and basic Types • Metric description • Configuration ? • Change control

  10. 5. Discovery and Introspection • finding manageable resources • introspecting manageability capabilities

  22. Teams and Meetings WSDM – Attendance/reports/issues from teams, Th 12:00-2:00 Calls – Reuse existing time Work an issue during each call Mailinglist – Use wsdm list with prefixes for topics

  23. MUWS Action Items UArch - fix diagrams - Igor - unify logical models and roles – Igor/Homayun - information model - William - delegation model - William - processing model – buckets - Igor UMBB – Ellen Stokes

  24. MUWS Action Items UPlat - assigned champions, rearranged - Identity of Endpoint – from WSDL - Identity of Resource – to MMB - Versioning – Brian spec version – WSDM resource version – to MMB service versioning – Platform? MOWS? - Attributes – Heather resource attributes – to MMB? Grid coop? - Metadata – Grid coop? Homayun - Addressing – Heather - Notification – Igor interim solution? - Relationships – to MMB

  25. MUWS Action Items UPlat - Security – high, John DeCarlo (Hal, Fred help) - Registration/Discovery – no addt’l reqts if we need a resource registry it will be management specific - Policy – med, wait for market development - Collection – high, to MMB - Transactions – med, wait for market development - State Model – of resources, to MMB - Lifecycle Model – med, of resource instances, for market development - Name Resolution – med if we need a resource name to reference resolution we will do it management specific

  26. MOWS Action Items • Proposals on manageability endpoint • managing one wsdl:endpoint (Igor) • vs managing multiple wsdl:endpoint (William) • Clarify Versioning requirements (Igor, Brian, Mike) • Fix Versioning UMLs (Igor, Brian, Mike)

  28. Liaisons • DMTF – work register from Winston, Winston will take to • DMTF and post it for approval • GGF CMM – members of CMM join WSDM to do base work • and use WSDM specs in CMM work. • ? CMM concepts glossary useful for our glossary? • DCML Liaison? Not yet , Igor informally through CA

  29. Liaisons & contact points • for staying in synch, we depend on them • depend on us? • Points of contact w/in Oasis that can keep in touch, informal liaisons • GGF CMM – Ellen & Jim Willits • OASIS Provisioning – Darren Rolls • WS-Security – Hal Lockhart • DMTF – Andrea Westerinen + Karl • TOG – Karl Schopmeyer • W3C-WSArch – Heather Kreger • W3C – WSDL 1.2 – Igor Sedukhin • Oasis – BPEL - Sanjeev • IETF/netConf – watch • JCP/JSR077 round 2 – watch (guru bhat, karl s.) • WS-I – basic profile implications • WS-I - manageable profile in future • DCML – Igor Sedukhin
