Q2

  • Chair: PK
  • Scribe: AS

Discussion on FHIR

  • Serialization rules
  • Lack of consistency in the specification
  • Issue with order in XML

Q3

  • Chair: PK
  • Scribe: PK

Issue: The relative urls defined previously to refer to resources are not proper relative urls, eg “../patient/@123”.

Given the above and that the solution using xml base results in a correct but too complicated solution it is recommended to change the data types used from ‘url’ to string with the guidance that the string may contain and url fragment which is relative to the service base, eg “patient/@123”.

  • Motion: Lloyd, Steve Glinski 13-2-0

Issue: Searches are a problem given: the lack of ability to specify ‘and’ and ‘or’ relations between name-value pairs; string parameters being specified as allowing for partial matches, and three other classes of issues.

Q4

  • Chair: PK
  • Scribe: PK

Move that we approve the changes to the search system in FHIR to support a richer and more client-specified search methodology.

  • Motion: Lloyd, Grahame 16-1-0

Issue: The Sort order of the returned values in a search is not currently specified.

  • Add a Sort parameter.
Discussion of rendering of FHIR instances with extensions inline at the same level as the core elements.

There was discussion of the rendering of FHIR instances either with Core elements and multiple Extension elements where the extension contains the identification of the extension component and the extension data elements themselves. An alternate rendering form was discussed where all elements, core and extensions could be expressed at the same level. The concerns were raise that departing from the current FHIR rendering approach would increase the complexity and move away from access to existing tools and technology, and that generally it was not considered to the in the implementers ultimate interest. However, it was recognised that for some this latter format could be pleasing and that the FHIR standard does contain recognition and a description of this, although it does not provide the specific implementation, through the notion of generating object management code which presents the instance object to the implementer as described while keeping the wire format as is. ECG Data types – reviewed the need to be able to express a reference to a file of observations rather than an inline list of observations. The reference needs to contain both the actual file reference as well as some meta-data about the file to support file contents loading and interpretation. The result of the discussion was to suggest replacing the single data elements with the new element containing the meta-data.

  • Move that the FHIR mime types be changed follow the pattern: application-FHIR+xml and application-FHIR+json.
    • Motion: Grahame, Lloyd 18-0-0
