  1. Draft 02 X Paradigm layered architecture Starting Point S. Lotti HL7 Italia Chair Enterprise Architect at Invitalia – Government Agency for Inward Investment Promotion and Enterprise Development HSSP

  2. Objective of Layered Architecture (from wiki) • The overall approach to layered service architecture is to extract common elements from project artefacts performing similar capabilities into a “platform specific model” and consider a multiplicity of platform specific models based upon the differences. • Initial ideas are: • Map artefacts into the SAIF framework as was done in Practical Guide Part II with an eye to separating platform independent elements from platform specific ones. • A decision tree through the stack will be graphed. The output of task #1 may or may not be appropriate as a starting point. Particular paths of choices through the stack may represent particular existing artifact choices (example: IHE XDS profile). Again the purpose is to find the common elements vs. differences and provide raw material for generating a deployment that enables disparate systems to interoperate. HSSP

  3. SAIF - Interoperability Specification Matrix HSSP

  4. X Paradigm specs in SAIF ISM Common part (Platform indipendent) Conformance assertion analysis Platform Specific part ? ? • Mixed implementation environments are also theoretically possible HSSP

  5. SAIF – ISM and Xparadigm Artifacts HSSP

  6. Logical progession (partial) Bottom up With existing specs HSSP

  7. e.g. Service architecture design • Layered Service Inventory • BPMN2 Choreograpy • BPMN2 Collaboration • Service Architecture (SoaML from STMs PIM) - Use case (narrative) • Business Vocabulary (SBVR) Process Services Entity services Utility services HSSP

  8. Business Vocabulary (SBVR) • The Vocabulary will be designed with SBVR (with a simple UML profile) • SBVR will be used for role/actor modeling and also for conceptual information modeling HSSP

  9. BPMN2 Collaboration • Business Vocabulary (SBVR) Narrative Use Case • The processes will be derived from narrative use cases and vocabulary (participants) HSSP

  10. Service Architecture • BPMN2 Collaboration • Service Contracts & • From BPMN collaborations will be identified the operations and mapped on the service architecture and contracts (from STMs) Service architecture Contract Retro-modeling from existing standard specs is necessary HSSP

  11. BPMN2 Collaboration • BPMN2 Choreograpy • From BPMN collaborations will be defined the choreography or the orchestration(s) (if possible or useful) HSSP
