Minutes

Minutes/Conclusions Reached:

Sunday Q1

• Call to order
  • Called to order at 9:15am U.S. EDT.
• Approval of Agenda for quarter
  • Approved by affirmation.
• Approval of agenda for WGM
  • Approved by affirmation.
• Approval of Minutes
  • Approved by affirmation.
• Update from TSC (Ron/Charlie) (30-45 minutes)
  • Reviewed Roadmap - committe renamed to Strategic Initiatives Committee
  • Publishing facilitator will coordinate our Glossary work with Publications
  • Concern was raised that many of the HL7 leaders are consultants
  • Jane Curry agreed to be publishing facilitator
    • Discussion was held on what level the glossary should exist, as well as other HL7 content. Publishing/Tooling long term goal is to not only create a single ballot package, as well as custom view package - where all the links work.
    • We need a business process as well as a set of tools to make it real. Some people recognize the need, some do not.
    • There is a number of people who just want to get their job done, and not be concerned about the enterprise.
  • Tutorials need some form of validation
    • e.G. Security COnsiderations Cookbook is tutorial with very "Authoritative" language

MOTION: Approve Jane Curry as Publishing Facilitator: Unanimous

• • Arb to ensure the definition of what constitutes "Substantive change" is done
    • Woody suggested we delegate and include more than one other WG (MnM + ??)
    • Should include versioning/sunsetting issue as well.
    • Was a role of the old ARB.
    • Ended up clarifying rules to prevent ARB from being court of appeals for Substantive Change.
    • Original document defined substantive change as anything that breaks wire format
    • With the advent of V3 xml change in wire format was not necessarily substantive.
    • Grahame Grieve: Arb should specify a statement of value - what is substantive change at the highest level. Then create a task force to generate rules for a specific specification set.
    • John Koisch: Each specification could provide it's own substantive change rules.

Grahame's Definition: Substantive change is any change in a specification that causes changes to conformant implementations, except in as much the implementation leverages technical publication artifacts directly.

• • Replace Services with Service (change plural to singular).

MOTION: Change the S in SAIF to singular. Unanimous approval

• • SAIF transition from ALPHA to BETA+
    • Calvin Beebe's presentation on application of governance.
    • Suggested that we pick a probblem, apply SAIF end-to-end, and refine:
      • Governance
      • Implementation Guide
      • Methodology
    • Charlie Mead will discuss experience at NCI with TSC - around four/five points:

1. Value propositon
2. Have a clearly defined scope to apply SAIF
3. Come to terms with defining artifacts and meta-data
4. Governance must recognize that you cant govern everything - look at the life cycle, and the risk of not governing certain aspects.
5. There must be a notion of change management recognition.

• • • We need an architecture informed by SAIF
    • What are the working elements of SAIF that apply regardless of messaging, documents, and service metaphors and determine how to govern "that"

• • Set direction for the week.
  • Arb Membership Criteria Review
  • SAIF Glossary Review

Sunday Q2

• Sunday Q2
  • Call to order
  • Approval of Agenda for quarter
  • Behavioural Framework (John Koisch)
    • Summing up discussions - status report
• History

1. Started with HL7 dynamic model
2. Services Oriented Dynamic Model
3. ArB SAEAF conformance stack
4. The Behavioral Framework - adoption of requirements for messaging and services

• Work Streams

1. OO Dynamic Model - Analysis model
2. MnM & ArB Discussions
3. InM + SOA + OO Discussions - Gone but the actors remain
4. Implementation Guides (From NCI, etc)
5. Services for RIMBAA - fringes of BF discussion on how BF enforms RIMBAA
6. Patient Registration - Detailed analysis - when patient reg was broken into services, it was not one-for-one as expected.

• Comments and Reconciliation
  • Three types of comments

1. Content-driven (Definitions and terminology) 2. HL7 Strategic (Does the BF buy HL7 things in terms of SAIF, or outside of SAIF) 3. HL7 Engineering "People do not need visibility of the BF ...they need the imputs to MIF"

• • Realizations
    • BF isw coherent, but that stands in the way of acceptance
      • It talks about traceability for deployed interfaces

It binds RM-ODP to create a vocabulary and grammar for discussing behavioural models It is generic with respect to tooling and not necessarily HL7 Specific It shifts the focus of HL7 givens from information focused to specification focused Doesnt include concrete instantiation(OO not working on it)

• • Huge Question
    • Does HL7 care about services
      • Does HL7 care bout workflow resolution in the standard?

Jane Curry: Workflow is important - but is it bottom-up, or top-down? You can from the bottom identify the states, and the precedence, but you cannot identify the authority - which is non-standardizable. governance problem.

Ron Parker: If we can get people to adopt this behavior, can we change the toolsets.

Jane Curry: We have a long-transaction. Admit a patient for an encounter is a huge payload.

John Koisch: HL7 Does care, but the model wont support it.

John Koisch: Is HL7 prepared to think in terms of explicit, but extensible, contracts or are we coing to have focus solely with the information components?"

Grahame Grieve: HL7 is uniquely focused - most others provide working standards, while we often provide frameworks. At what point is HL7 a horizontal provider of standards, is it a wise thing for us to split into two levels?

Charlie Mead: HL7 implementing an HL7 SAIF IG as the authoritative model will inhibit industry adoption.

Grahame Grieve:

• • • • • You cannot talk about behavior unless you are willing to talk about decomposing information
        • What is being standardized WILL change; There WILL be more STANDARDIZED PIECES
      • I Do believe that we can determine all of the pieces that make SAIF or the BF work ahead of time - this is a proactive
  • Initiate Reponse to TSC on "Substantive change"
  • Glossary Review

Sunday Q3

• • Call to order
  • Approval of Agenda for quarter
  • Behavioural Framework (John Koisch) ???
  • Coherence ???
• Adjourned <hh:mm am/pm> <timezone>.
