Behavioral Framework Background & Terminology
Behavioral Framework: Introduction • Background .. • What was the goal ..
Behavioral Framework • Provides a grammar to enable interoperability in complex, multi-enterprise domains (e.g. healthcare, life sciences, etc.) • Captures behavioral metadata that is considered SOA Best Practice • A number of public domain SOA models and specifications capture equivalent information • Several competing representation standards address the semantics of the BF, e.g. BPMN2, soalML, CDL, etc. • Leverages existing standards (especially RM-OPD) • Can be extended/localized to address specific behavioral requirements focused on cross-enterprise interoperability • Applicable to multiple interoperability paradigms (e.g. services, messages, documents) • Formalizes the notion of contract • Contracts are currently only implied in most service specifications
BF Concepts: Roles • Identifiers for “collections of behavior” • Identify a cohesive set of invokable capabilities, capacities, or competencies • Assignable to a system or an object • An object or system may have multiple roles • Single role may be assumed by multiple objects or systems • Examples: Order Mgmt Service, Specimen Mgmt Service, etc. • Roles are involved in Interactions • Each interaction involves two types of roles • Commissioning Agent ( Service Consumer ) • Responsible Agent ( Service Provider ) • Roles are realized through Service Specifications Role
Behavioral Framework: Concepts • Accountability • Interactions that realize • A business functions • Obligation Interaction 1 Interaction 2 Interaction 3 Commissioner Agent (Service Consumer) Responsible Agent (Service Provider) • Behaviors Role
BF Concepts: Accountability and Behavior • Behaviors in the SAIF BF are realized through service operations & Functional Profiles • A defined behavior is realized through an Interaction (a service operation call) • Accountability in the SAIF BF is realized through Functional Profiles and logically conjoined Interactions • Function Profiles provide accountability by grouping behaviors • Accountability example: successful placing of a lab. 1 2 3 Commissioner Agent (Lab order placer) Responsible Agent (Lab order fulfiller)
BF Concepts: Interactions • Roles have defined behaviors that can be realized through (internal) Actions and (external) Interactions • The BF is scoped to Interactions only. • Interaction example: Place a lab order Promise Lab Order! Order a Lab! Interaction
BF Concepts: Obligations • Obligations • Define the scope of Role’s Interaction, i.e. specific “tasks” or “deliverables” that the responsible Role must accomplish over the course of the Interaction
BF Concepts: Contracts • Contracts in BF define Interactions between Roles • Contracts specify • Overall requirements for the two roles in each Interaction • Interaction patterns/information flow direction and specifics • Accountabilities • Permissions • Restrictions • The BF refers to contracts as “Contract Template” • Emphasizes the fact that a contract can be robustly defined before it is involked
The Accountability Pattern and Contracts • Contracts aggregate Accountability, typecast Parties, and define Actions to support Accountability Types. • In other words … contracts bind design time specifications (Knowledge Level) to run time components (Operational Level) • Knowledge level: travel agents issue tickets for a traveler through the Accountability Type of Travel Agency • Aperational level, Expedia issues Joe a ticket to Kyoto • Parties: Joe (commissioner) and Expedia (responsible) • Accountability: The activities around Expedia acting as a Travel Agent for Joe, i.e. create an account, purchase ticket, deliver ticket, check flight
Contracts and Conformance • Contracts provide the key to defining conformance • Conformance relies on evaluating the interactions between roles. • Interactions are enabled behavior between two roles that are bound to interfaces that allow them to perform actions to support some goal.
