Discussion

• Group discussed the way(s) ‘Must Support’ needs to be defined in the Canadian Core; need to have clear expectations
• Sheridan walked the group through her chart which proposes 4 main configurations, each of which deal with 2 scenarios: Query & Create/Update
• Client = requester, server = responder
• Good amount of back and forth re: sending a data element with no value (as opposed to just not using that element at all)
• Some reviewers feel it would be odd to have a 1..1 cardinality and not also have a must support flag
• Topic raised of eliminating the data absent reason extension; relevant discussion are being had in other groups like HL7 Conformance Group, will want to ensure the efforts between these groups are consistent
• Hoping the approach of not using ‘data absent reason’ sees international adoption
• Should add some wording on dealing with modifier elements when an element is must support + 1..1, i.e. does the requester have to consume a modifier element no matter what because it fundamentally impacts the interpretation of the information coming back
• The focus of the must support flag in the query scenario is really the server; we shouldn’t set expectations on that the receiving client had to do with the data it receives
• Current Version of the Must Support Definitions, configurations, and scenarios can be found here: infocentral.infoway-inforoute.ca/en/resources/docs/hl7/canadian-core-profiles

Hi all,

For tomorrow's Canadian Core Governance Call hosted by the Solution Architecture stream, the purpose of the call will be to review a Must-Support Matrix that Sheridan has put together, which defines the various scenarios in which the Must Support flag may apply, and how the use of the flag may change in those different scenarios. The objective will be to work through these various scenarios in an attempt to come to an agreement on how the Canadian Core defines Must Support in these cases.

Thank you!
