Objectives

  continue to reap maximum benefits from HL7
• Minimize risks that we see as HL7 3.x moves
  forward

  Version 3 processes

Issues

• Methodological
• Focus and abstraction level of the RIM
• Role and ability to apply RIM to non-messaging
  technologies
• Notational
• Style guide practices
• Meta-model constraints

5
Observations

• VHA is having a difficult time relating to the
  new RIM
• Not all current HL7 practices are reflected in
  the MDF
• Some style guide constraints result in
  counterintuitive representations
• Modeling guidance has not kept current with
  industry
• Profiles for UML
• Role names
• Constraint representation
• Methods

6
Recommendations

• Form a sub-committee to
• make current HL7 methodologies
• address lessons learned
• incorporate industry best practices
• address UML revisions
• extend the methodology to support CDA and
  Templates activities
