A New Normative Standard for Value Set Definitions

Overview

[From the PSS] Describe the elements that make up a “Value Set Definition”, and ballot this as a normative HL7 specification, including a demonstration of how this is met in FHIR profiles and HL7 Model Interchange Format (MIF).

The definition of value sets is a required activity in completing the specification of most health information technology artefacts. To date, the approach for doing so has not been consistent within HL7 constructs and elsewhere. Many of the required elements and approaches are embedded in existing HL7 artefacts but not consistently. Currently, an explicit list of all the fields in an HL7 value set definition are surfaced only in the informative balloted MIF, with a general description of them in the normative Core Principles specification. A more accessible and standardized list of these fields is required to facilitate interoperability and sharing of value set definitions across HL7 artefacts and the Health IT community at large.

Success criteria: Publishing of the normative standard, and a demonstration of value set definitions that conform to this published normative specification.

Upcoming Meeting Agenda post WGM (5/13/14)

  1. 30 min: Logistics and key prior discussions
    1. Determine weekly meeting time and day. The current Tuesday 4-5:30p ET slot:
      1. While acceptable to our global community, overlaps some key meetings and normal life events.
      2. Current time is 6am in AUS and 9pm in UK. Thereby it may be that any change in the time will cause significant pain at one end of the globe.
      3. A change in day may help some folks.
    2. Quick review of discussion at non-vocab discussions
      1. Discussion with FHIR alignment on value set profile Monday Q3
        1. GGreive will create value set profile consistent with VSD, including extensions for non-base elements.
        2. We will consider adding multiple identifiers for VS
      2. M&M and SD
    3. Vocab meeting was general overview
      1. Presentation given is here.
      2. See Vocab minutes
    4. Ballot target remains September 2014 (August submission). PSS due soon
  2. 60 min: Continue document work
    1. Finish discussion of PostCoordinationControl element
    2. Then continue discussion of ballot document section 5 items
      1. First, Review the STATUS work done 4/22. Section 5.2.3.3.1 - 5.2.3.3.4
      2. Potentially Discuss how proscriptive the spec should be to control different implementation interpretations.
      3. Discuss overall datatypes: MaximumMultiplicity datatype
    3. Consider continuing to Expansion Set section, or other
    4. Some of the sections have been "signed up for"
      1. RMcClure and JJames will focus on sections 2 and initial section 5
      2. Still hope HGrain will work on section 3
      3. WHuang and JCase will work on section 4
      4. Expect TKlein and LMcKenzie to work on front pieces and content of section 6
      5. WHuang will work on section 7
  3. We strongly hope that all participants will remain engaged in the project. This decision was not lightly taken and is a reflection on the amount of work and the importance of that work
    1. Additions to agenda?
  4. Running list of Completed Issues:
    1. We completed the review of the Logical Elements/Functions to define Content Logical Definition based on the MIF
      1. See Valueset MIF ContentDefinition for updated comments.
    2. Discussion on how to control use of DYNAMIC defined value sets continued on 12/20 meeting.
      1. Rob and Lloyd still have to create document and use cases to explain approach to "STATUS" / DYNAMIC stability.
    3. Metadata sheet review now complete
      1. Completed discussion of Value Set Expansion metadata with changes added to end of spreadsheet.
        1. A Value Set Definition can reference 0..* "Trusted Value Set Expansion Reference" that can be a service or an actual expansion
        2. An Expansion can be characterized by a date (required), a time (optional) and an identifier (optional)
    4. As of VSDSpec v18, UML model accurately describes those elements that are "definitional" in that if they change, a new value set or value set version should be created.
    5. 4/22/14 Completed documentation of determination of VSD version STATUSes
    6. This initial ballot will leave inclusion of concept expressions as value set members as OUT OF SCOPE. This remains highly important but will be addressed in the following ballot.
    7. This document has the abstracted decisions from minutes. [1]
    8. We will allow the use of slightly more complex datatypes (DSET and EN are currently used) [Example content attribute was discussed when this decision was reached]
Latest (v23) version of doc here.
