Agenda

• (Lloyd): Administrative topic: Dynamic Model - agenda
• (Lloyd): Hot Topics: Act Reference - postponed for next WGM because this topic requires input from INM.

Mottion to accept agenda: (No objections)

Administrative Topic: Dynamic Model Discussion

Concerns regarding desinging system behaviors are pervasive in HL7 (from application roles to committee-specific complex interactions to functional service specifications). We have a variety of constructs (Applications Roles, SOA Services, interactions) that require dynamic views and behavioral model constructs such as interfaces, ports, and subsystems.

The agenda for next week must address the needs of a variety of stakeholders:

• Support for the processes specified in the HDF regarding behavioral models
• SOA Service support and relating interfaces to Application roles
• Ability to describe complex interactions for specific domains
• Leverage the notation and design to describe a variety of in, in/out, output parameters and return types
• We need to ensure that our design constructs are supported by implementation technologies (e.g. WSDL, WS-CDL, WS-BPEL)

Dynamic Model Agenda (Harmonization Meeting June 21-22, 2007)

The agenda was created in a Dynamic_Model_Agenda_June_21_2007

Thursday, June 21st

(Q1) 9:00-10:30 am EST

Inventory of where we are with the dynamic model

• We will try to compile a comprehensive list of needs and issues with the current behavrior modeling.
• UML Activity diagrams were deemed too complex when they were suggestes as a means for documenting system behavior

(Q2) 11:00-12:30 am EST

Services and Application roles

• In this session we will discuss how we relate operations (in interfaces) to interactions.
• Map our interaction concepts to operations and interfacesrespectively
• The common denominator between service specifications and application roles may be to represent both as interfaces

(Q3) 1:00-2:30 am EST

Identify artifacts that will affected by changes to dynamic modeling notation, style guide, or methodology.

• Documenting and specifying complex interaction patterns
• Look for consensus on the mapping developed in the previous session

(Q4) 3:30-5:00 am EST

Complex interaction patterns

In this session we will look at some concrete examples

• Service orchestration vs. choreography
• We will not go into the solution for run-time representation of system (e.g. WS-CDL

WS-BPEL).

• • We will focus on the design time representation of interfaces not at the runtime realization.

Thursday, June 22nd

(Q1) 9:00-10:30 am EST

Develop approaches to "make it real"

• The methodology will be linked back to the product lifecycle management project in the HDT
• Select the notation

(Q2) 11:00-12:30 am EST

Open session
