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

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 61968 Verb examples: –Create, Created –Send, Reply Information Object examples: –EndDeviceAsset –MeterSystemEvent –MeterReading e.g. CreatedMeterReading
