  1. SG Systems - Service Definition Team Chair: Gerald Gray, CIMple Integrations gerald.gray@cim-ple.com Co-Chair: Shawn Hu, Xtensible Solutions shu@xtensible.com

  2. Introduction • Why Service Definitions? • Best Practice CIM implementation • “The CIM is neat but…” • The service definition process (high level view) • IEC CIM alignment • Future Plans

  3. You Are Here You are here

  4. Where We Fit Open AMI-ENT OpenADE OpenADR OpenHAN Use Case Team SRS Team Service Definition Team Interoperability Team Security Team

  5. System Requirements Specification The Process Use Cases Business Processes Integration Requirements • Services • WSDLs • XSDs For more info: http://osgug.ucaiug.org/sgsystems/SDTeam/Implementation%20Projects/Home.aspx

  6. The Process • Logical model input & development • Identification of integration requirements • Pattern naming • Information objects • Artifact generation • Posting • Issue generation and resolution • Versioning

  7. Logical Model Input • IEC 61989-9 and Multispeak are the primary model inputs • AMI-ENT: use case contributions from SCE, Consumers Energy • Open AMI-ENT, OpenADE 1.0 • On-going: OpenADR 1.0, OpenHAN 2.0, etc

  8. SDO – User Group Relationship • Iterative process • Analogy – early browser development SDO Yes and... Thou shalt... User Community Feedback • OpenSG OpenAMIENT example • First pass – IEC CIM draft XSD as informative • Now – XSD as normative

  9. IEC CIM Alignment Adapted from TOGAF 9 • Consistent –some features of the spec, and in accordance, but also some additional features • Compliant – some of spec not implemented, but what is implemented is in accordance • Conformant – All features of spec implemented, but some additional features that are not conformant • Fully Conformant – full correspondence between the spec and implementation. . Irrelevant . Consistent . Compliant . Conformant . Fully Conformant - Implementation - Specification

  10. Logical Model Development • Standardized actors from AMI-ENT SRS • Document business process in use cases and activity diagrams

  11. Identify Integration Requirements • Where an object crosses a system boundary

  12. Harmonize Integration Requirements • Compare integration requirements and look for commonality: • Common actors • Common consumers • Common providers • Common information objects • Eliminate duplicates, refine integration requirements

  13. Patterns – Using CIM Verbs • Pattern naming allows for both ESB and non-ESB (point-to-point) architectural assumptions • Verbs and Information objects are based IEC 61968 • Verb examples: • Create, Created • Send, Reply • Information Object examples: • EndDeviceAsset • MeterSystemEvent • MeterReading <IEC Verb><Information Object> e.g. CreatedMeterReading

  14. Notification • Subscribe to the Listserv • http://listserv.enernex.com/cgi/wa.exe • Send listserv e-mail • OPENSG-SGSYS-SD@SMARTGRIDLISTSERV.ORG • Issues with artifacts should be noted on the OpenSG Help Desk site • http://osgug.ucaiug.org/HelpDesk/default.aspx • Implementation Projects: Service Definition Team Wiki • http://osgug.ucaiug.org/sgsystems/SDTeam/Implementation%20Projects/Home.aspx

  15. Plans - Feedback • Current work was shared with IEC WG14 (Use Cases, Requirements, Artifacts) • Continuing service definition work… OpenADE 1.0 artifacts REST/SOAP ballot OpenAMIENT ballot IEC WG14 Re-factor artifacts Oct ‘09 Jan ‘10 May ‘10 Jul ‘10 OpenADR…
