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 May 3, 2010OpenSG - SG Systems - Service Definition2

4 Where We Fit August 12, 2009OpenSG - SG Systems - Service Definition4 Use Case Team SRS Team Service Definition Team Interoperability Team Security Team Open AMI-ENT OpenADEOpenADROpenHAN

5 May 3, 2010OpenSG - SG Systems - Service Definition5 The Process Use Cases Business Processes Integration Requirements Services WSDLs XSDs System Requirements Specification For more info: smartgridipedia.org: HOW-TO service definition document

6 May 3, 2010OpenSG - SG Systems - Service Definition6 The Process Logical model input & development Identification of integration requirements Pattern naming Information objects Artifact generation Posting Issue generation and resolution Versioning

7 May 3, 2010OpenSG - SG Systems - Service Definition7 Logical Model Input IEC and Multispeak are the primary model inputs Use case contributions from SCE, Consumers Energy AMI-ENT, OpenADE 1.0 Up Coming additions: OpenADE 2.0

8 SDO – User Group Relationship Iterative process Analogy – early browser development May 3, 2010OpenSG - SG Systems - Service Definition8 SDO User Community Thou shalt... Yes and... OpenSG example First pass – IEC CIM draft XSD as informative Now – XSD as normative Feedback

9 IEC CIM Alignment 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. May 3, 2010OpenSG - SG Systems - Service Definition9. - Specification - Implementation Irrelevant. Consistent. Compliant. Conformant. Fully Conformant Adapted from TOGAF 9

10 May 3, 2010OpenSG - SG Systems - Service Definition10 Logical Model Development Standardized actors from AMI-ENT SRS Document business process in use cases and activity diagrams

11 May 3, 2010OpenSG - SG Systems - Service Definition11 Identify Integration Requirements Where a process flow crosses an actor boundary

12 May 3, 2010OpenSG - SG Systems - Service Definition12 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 May 3, 2010OpenSG - SG Systems - Service Definition13 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 Verb examples: –Create, Created –Send, Reply Information Object examples: –EndDeviceAsset –MeterSystemEvent –MeterReading e.g. CreatedMeterReading
