Governance

  1. Discussion topics:
    • Feedback from FGB/FMG on roll back FHIR to the DSTU version and follow the process for DSTU update (John)
      • Lorraine reports there were many threads of (mis) communication last week but the recommendation from FMG and FGB to reconsider the rollback order with review of the changes that were made. Paul reports that a motion to that effect was passed by FMG.
      • Lorraine adds that there has been some discussion to decouple the reference implementations from the specification so that if we change the site we don't have to do a publication request. Woody points out that changing a hyperlink, on any ballot site, can follow another determined process and not have to involve the TSC.
      • Lorraine notes that making the portions of the spec distinct from the reference implementations would simplify that and improve their publication processes. Woody takes issue with the statement that "any change to the web site requires a publication request".
      • Austin suggests the FGB put forward a set of precepts for correcting typos versus real changes to the DSTU versus balloting, so that the TSC might review these precepts.
      • DSTU naming increment to DSTU Release 1.1 further discussed. Casting it as an errata instead would not increment the DSTU release. Change to errata publication made, and John will review this at the FGB tomorrow instead.
      • The technical build number is 0.80-2325
      • Lorraine notes there is an in-flight project for FHIR publication by ES; is this addressed in the project requirements? Paul reports it has requirements for in-flight development and historical reference releases. Requirements are still in flight and not solid yet.
      • Austin moves to reopen and reverse the motion seconded by Andy to roll back the DSTU release. Unanimously approved.

Management

  1. Discussion topics:
    • update on CDA XSLT security problem
      • Austin reviews the origin from a blog posting exposing issues for CCDS XSLT, with the transform dating back to CDA R1, not under source control. Rick Geimer started applying patches to the file and put it through a code review process last week with a team of individuals willing to participate. Rick published a new version last week addressing security comments. Other changes to the transform collected from requests were also incorporated and the file has now been placed under source control. This transform has been included in over 50 download packages on the web site historically. He reviews the considerations of retrofitting these files or pushing out the changes to any user of any of those files. He suggests including a warning message and directing the downloader to the GForge package release. Removing the old versions of the file also under discussion.
      • SDWG has taken the lead on this though II and CG have also included the transform in their related files. eMeasure also has the vulnerability. A number of other xsl files have not been evaluated, e.g. Arden or CCD-to-BlueButton. Woody notes that the xsl typically produced in HL7 did not include a specific defense against the vulnerability. He also reports the ballot website transforms have been altered to protect against malicious use.
      • Austin notes the release on GForge is nearly ready for public announcement but addressing the approach to the prior download packages remains. Woody feels widespread correction is not worth the energy to do so. Austin would like to address with a warning to downloaders and not retrofit the other packages. He will be preparing an errata publication request with notification to II and CG to opt in to the notification changes and will send to John this week. Austin moves to adopt this approach. Woody seconds. Unanimously approved.
      • Austin asks if the TSC wants to recommend that these sorts of files not be buried inside the release packages for the standards. Woody notes it may be too general a recommendation though we may want to put some guidelines around what is to be done with them. Austin recommends discussion on a future call.
  2. Review action items –
    • Develop formal definitions of backwards compatibility and dot-releases in the GOM. While there were allusions to this issue in the discussion, there were not specific items to discuss. Woody cautions about locking these into the GOM. John suggests he discuss with Ken on next Friday's call.
    • WGM follow up on IP restrictions (Target date March 10) - followup to the cochairs dinner meeting in San Antonio. John has recommended this be addressed at the WGM Board Meeting, now that we have a sitting elected Board Chair. He is sympathetic to Ken's difficult position between a rock and a hard place and especially concerned about enforcement.
      • Ken will follow up on whether to make available the reconciliation spreadsheet when it only contains snippets of the standard
      • Ken and John will need to discuss IP protection of V3 development content - not discrete documents e.g. IGs.
      • Ken and John to go back to the board with Woody's recognition of development material restrictions as a threat to the ability of the organization to do its collaborative work
    • Feedback from the US Realm Task Force of their review of the modified Affiliate Project Approval Process and how best to include the modifications into the US Realm Task Force role (not yet ready for response by US Realm TF)
    • Andy to address with Tooling WG where we provide tools that we must also address the security measures in those tools and transforms. Other ideas were to include in the PSS and/or in the publication documents to state that as an implementer you must evaluate your own security risks. Andy has no further comment on this. Tooling discussed the security stuff on the call but did not have recommendations to go forward yet. John will also discuss with Ken on their planning call.
  3. Approval items:
    • DSTU update publication request for HL7 Implementation Guide: Clinical Decision Support Knowledge Artifact Implementations, Release 1.1 requesting name change to HL7 Version 3 Standard: Clinical Decision Support Knowledge Artifact Specification, Release 1.1 for CDS WG of SSD SD at Project Insight #931 and TSC Tracker 3104 (Bryn Rhodes) as reviewed on 20140408_US_Realm_TF_Call; Andy moves and Pat seconds approval of the publication request with the name change. Unanimously approved.
  4. Discussion topics:
    • Conformance Testing update - JQuinn met with CDC on April 8th
      • John reports the CDC is interested in expanding what was done with the HIMSS demo for Immunization registry and next steps. There may be interest for conformance testing on automated submission processes for the CDC. John asked that Dan come back with some suggestions.
      • Austin cautions that the persons he had talked to represented select areas in the CDC and other silos exist.
