3 Session Agenda OGSA activity status update and future plan Tom Maguire and Hiro Kishimoto, co-chairs –What is OGSA Architecture –OGSA document status update –Interim meeting report –Guidelines –Works in progress Modeling Grid resources in OGSA Fred Maciel, Rsrc Mgmt Design Team Lead OGSA on WS-Management et. al. Glenn Wasson, University of Virginia.

4 What is OGSA Architecture Open service-oriented architecture –Based on Web services –Addressing Grid scenarios Component-oriented architecture –Interchangeable components Meta OS functionalities –Distributed and heterogeneous environment A rendering of these functions –Based on Web service architecture and specifications GGF’s flagship architecture and the blueprint for standard grid computing

5 OGSA Design Philosophy Service Oriented Architecture –Resources as First Class Entities Expressed as WSRF-Resource Properties –Data type extensibility and introspection –Dynamic service/resource creation and destruction Component-Based –Elements of the Architecture are pluggable Customizable –Support for dynamic, domain specific content,... –Within the same standardized framework

F2F meeting in Washington DC –Community needs “implementable specs” –Agree to start OGSA profile development 2005 first half –Mainly focus on low-level “profile” work –“OGSA WSRF Basic Profile 1.0” 2005 second half –Add middle-level work EMS architecture Information model for Grid Resource

10 Session Agenda OGSA activity status update and future plan Tom Maguire and Hiro Kishimoto, co-chairs –What is OGSA –OGSA documents status update –Interim meeting report –Guidelines –Works in progress

11 Defining the Grid: A Roadmap for OGSA™ Standards Purpose: –Clarify the meaning and role of OGSA standards –Provide a framework for managing future work –Identify documents, schedules and dependencies 6 informational documents 8 normative documents 3 recommended profiles –Document external activity: Opportunities for collaboration Contributory work Published as GFD.053 (’05/9) –Publish new versions regularly, at least annually

12 OGSA Profile Definition 1.0 Definition of “OGSA profile” –A profile specifies requirements on referenced specifications to improve interoperability –A profile has “conformance statements” and “extension points” –3 types of profile Informational profile Recommended Profile as Proposed Recommendation Recommended Profile as Grid Recommendation Enters 30-day public comment period –Please read and comment through GGF web site –Public comment review will end October 30

13 OGSA WSRF Basic Profile 1.0 Extension of WS-I Basic Profile 1.1 Includes protocol requirements for –Exposing state, lifetime management, notifications Submitted to Editor in September –Will start public comment period soon! Security session is Separated out –“Secure channel” and “anonymous channel” profile are under development –OGSA WSRF Basic Profile is combinable with any of OGSA Basic Security Profiles

19 OGSA Evolution Policy Statement GFSG document approved on April 19 th –GridForge Editor project: “Author Guidelines” OGSA Profile Policy –Must build on the WS-I profiles –Must be consistent with the OGSA Architecture (GFD.30) Note –Profiles may be inconsistent with each other –Disadvantage is different Profiles may not interoperate without modification or adaptors –This is offset by the advantage of a greater degree of flexibility and innovation within OGSA and the GGF

20 OGSA related working group, research group and specification naming guideline GFSG document approved on May 5 th –GridForge Editor project: “Author Guidelines” OGSA prefixed group –Output should be consistent with the overall architecture –Synchronize activity with the OGSA-WG and other OGSA related WGs –Output should “build on top of” or “can be combined with” OGSA Profile or interface OGSA prefixed document –Should be consistent with the overall architecture –Should “build on top of” or “can be combined with” OGSA Profile or interface

21 OGSA™ trademark usage guideline “OGSA” is a trademark and servicemark of GGF –Trademark: e.g OGSA™ standards, OGSA™ roadmap –Servicemark: e.g. OGSA SM workshop –Not yet “registered” or ® No official guideline by GFSG at this moment OGSA-WG’s current usage guideline –Use the (tm) or (sm) marks on first mention only, drop the marks afterwards –Add a “trademark” section on the front page mentioning "OGSA is a trademark of the GGF“ –Use it as a proper adjective
