  1. ebSOA Based on FERA Reference Model Vasco DrecunCollaborative Product Development Associates, LLCGoran ZugicebXMLsoft Inc. April, 2005

  2. Activities • Inputs/outputs • Flows • Deliverables • Dependencies • Transactions • Decisions • Contracts • Documents • Interfaces • Security • Messages • Registries • Repositories • Content maps • Services • Events • Agents Patterns or use cases of information exchange Reference models SOA standards BPM FERA FERA reconciles BPM with SOA April, 2005

  3. Recognizing FERA configuration • Four process characteristics determine what FERA configuration is required • Human interaction determines the need for portal and collaborative services capabilities • Sign-on, authentication, plug-in services (meetings, calendars, chat, visualization, reporting, etc.) • Process administration determines the need for federation server and gateways • Security, protocols, content exchange formats, meta-data mapping, B2B process standards (RosettaNet, CPFR, …) • Process flow determines the need for event management • Alerts, Escalation, Messaging, Queries, Flow controller • Business logic reconciliation determines the need for agent framework • Synchronous vs. asynchronous reconciliation April, 2005

  4. Mapping to FERA components Reference model steps • Step1: Define content and context elements (static view – Federation Information Model (FIM) and Collaborative Process Information Model (CPIM)) • Step 2: Define choreography (dynamic view) – Collaborative Process Flow Information Model (CPFIM) and Agent Interface Information Model (AIIM) • Step 3: Determine FERA configuration. Four configurations are formally specified and they support all possible collaboration cases (patterns) examined so far. • Step 4: Document FERA capabilities and specific features required to support the choreography (requirements) • Step 5: Select applicable standards for the specified capabilities and features • Step 6: Produce a final document with all architectural requirements and components to support the pattern • Step 7: Deploy to ebSOA April, 2005

  6. ebSOA Information Model • Federation Information Model (FIM) – Content and Context • FIM is an informational bridge between the public and private world. • Definition of federate profiles, business process specifications, collaboration protocols and agreements, security policies, etc. Information that supports public processes and documents of any type for both public and private processes. • Agent Interface Information Model defines types of agents, invocation rules and status control. • Collaborative Process Information Model (CPIM) • Supports complete CP context including all possible flows, participants and shared context elements like metrics, rules and joint events • The main CPIM entities are: CP Flows, Roles, Rules, Metrics and Clusters of Events • Collaborative Process Flow Information Model (CPFIM) • Supports definition of the possible flows of activities, decisions and events within the CP • The main CPFIM entities are: Activities, I/O-s, Events, Triggers, Decisions, Sequences, References, etc. April, 2005

  7. ebSOA Collaboration Semantics • ebSOA collaboration semantics in connection with ebSOA information model provides full dynamic collaboration support. • ebSOA collaboration semantics formally defines all necessary interfaces with methods/functions required for the collaboration data (ebSOA information model) manipulations and interactions between SOA Federation architectural components. SOA Federation is a central block of the ebSOA architecture with the following components which interfaces and methods/functions are already defined as a part of the ebSOA architectural specification: • Gateway • Portal • Plug-in Services • Security • SOA Federation (Federation Server, Agent Framework, CP Flow Controller and Collaborative Services) April, 2005

  9. ebSOA Specifications • ebSOA Specifications include both static (SOA Federation Information Model) and dynamic view of the ebSOA architecture. The dynamic view support includes formalized ebSOA collaboration semantics of the SOA Federation internal collaboration and its interface for the external collaborations (federated systems) via Federation Server and Gateway. • The key components of the ebSOA Specifications include: • ebSOA Information Model that fully supports informational aspects of both external and internal collaborations • Collaboration semantics and interfaces for • Gateway • Portal • Plug-in Services • Security • SOA Federation (Federation Server, Agent Framework, CP Flow Controller and Collaborative Services) April, 2005
