Minutes

• Woody gave an update on the Tooling WG's decision to make sure graphic notation is not dependent on color only to distinguish different types of things.
• Motion (Patrick/Andy) to approve last week's minutes. Motion accepted unanimously.

Hot Topic -- RMIM Diagram Representation

• Because of issues in supporting the traditional HL7 iconography using 3rd party tools (e.g. eclipse UML diagraming tools) there is a discussion about what approach HL7 should take in the future for representing artifacts graphically.
• Woody pointed out that we currently don't have a common example in each of the proposed representations that we can use to compare the representations effectively.
• Questions we need to consider:
  • How willing are HL7 members to move to a new representation?
  • What are the perceived requirements?
  • How would we make a transition? Training?
  • What are the costs associated in making a change? This will clearly be a major effort.
• Lloyd reviewed the benefits of each representation as described in the hot topic.
• Do we believe HL7 should have a single diagram syntax for RMIMs and HMDs?
• Are we committed to leaving the Visio tools? Tooling WG has said that the direction is to move from Visio to an Eclipse-based equivalent. The consensus on the call is that no one wants to stay on Visio-based tooling.
• Does it make sense, just to move away from Visio, to move to a non-traditional representation for a period of time and then to move back once the traditional representation can be supported on non-Visio tools?
