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

Behavioral Framework: Concepts
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.

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
Interaction
Order a Lab!
Promise Lab Order!
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
• 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 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
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.
