Changes documented in [http://www.hl7.org/documentcenter/ballots/2010SEP/reconciliation/recon_v3_cppv3models_r1_n4_2010sep.xls spread sheet].
 
 
===Item 33 [at 3/3.4.1.1] (M Neg-Mi) 0/0/0===
 
=====Voter Comment=====
 
I have *no clue* what this is saying.
 
=====Disposition & Disposition Comment - "tbd"=====
 
 
 
===Item 34 [at 3/3.4.1.1] (M Neg-Mi) 0/0/0===
 
=====Voter Comment=====
 
Not true.  The association end names (traversal names) are determined separately for each class in the choice hierarchy.  While some association end names may indeed be constructed using the name of the target class, this has nothing to do with choices.
 
=====Disposition & Disposition Comment - "tbd"=====
 
 
 
===Item 35 [at 3/3.4.1.1] (M Neg-Mi) 0/0/0===
 
=====Voter Comment=====
 
One of the defining features of a LIM is that it is never used as an expressed model.  If it's used as an expressed model, then it's a SIM.  If we're not happy with usage being a characteristic of whether something is a LIM or not, then we should just say that LIMs have incomplete classes and accept that templates might be LIMs or SIMs.
 
=====Disposition & Disposition Comment - "tbd"=====
 
 
 
===Item 40 [at 4/4.1] (G Neg-Mi) 0/0/0===
 
=====Voter Comment=====
 
This doesn't make sense.  Drop the sentence or change.
 
=====Disposition & Disposition Comment - "Not persuasive with mod"=====
 
Problem is the second paragraph should become the final sentence of the first paragraph.  In that case, this reference (which opens the third paragraph) does make sense because the non-update mode uses of reference are summarized in the first para.
 
 
 
Will make the change of combining first two paragraphs in this section.
 
 
 
==Reconcile Core Principles A-* Votes for Section 1==
 
 
 
<big>'''Filter:'''</big> Section='''4.1''' and '''3.4.1.1'''; Vote and type='''Neg-Mi'''; For = '''0'''
 
 
 
===Item 1 [at 1/1.1] (B A-S) 0/0/0===
 
=====Voter Comment=====
 
As it stands, it looks like you first constrain for realm, then for clinical practice.  In fact the reverse is usually true.  We shouldn't be implying any type of order.
 
=====Disposition & Disposition Comment - "Persuasive"=====
 
Make the change
 
 
 
===Item 2 [at 1/1.1] (B A-Q) 0/0/0===
 
=====Voter Comment=====
 
Is UML an "essential feature"?  I'm concerned that the wording will be misinterpretted to mean that where we diverge from core features of UML, we will be seen as violating this premise.  As well, it's hard to argue that the vocabulary model is based even vaguely on UML.
 
=====Disposition & Disposition Comment - "Persuasive with mod"=====
 
Propose to make it "and that, to the extent possible, these models will be based ..."
 
 
 
===Item 3 [at 1/1.1] (B A-S) 0/0/0===
 
=====Voter Comment=====
 
=====Disposition & Disposition Comment - "Persuasive"=====
 
Make the change
 
 
 
===Item 4 [at 1/1.1] (B A-S) 0/0/0===
 
=====Voter Comment=====
 
When we publish the RIM, we don't refer to releases, we refer to versions.  So it would be useful to include the version as a cross-reference. 
 
=====Disposition & Disposition Comment - "Persuasive with mod"=====
 
Release 1 (version 1.25) of the RIM …"
 
 
 
===Item 5 [at 1/1.1] (B A-Q) 0/0/0===
 
=====Voter Comment=====
 
We're going to ISO regularly with the RIM now, aren't we?  Do we really need to be specific about which versions have gone to he RIM?
 
=====Disposition & Disposition Comment - "Not persuasive"=====
 
Not yet - agree once we do.
 
 
 
===Item 6 [at 1/1.1] (B A-T) 0/0/0===
 
=====Voter Comment=====
 
The spacing between the bullets is different.
 
=====Disposition & Disposition Comment - "Persuasive"=====
 
Reomve second <br/> after second bullet
 
 
 
===Item 7 [at 1/1.1] (B A-Q) 0/0/0===
 
=====Voter Comment=====
 
Technically, only the Datatypes ITS is a CEN and ISO standard.  Abstract Datatypes is not.
 
=====Disposition & Disposition Comment - "Considered - Question Answered"=====
 
Yes, but that is a nuance that few would understand.
 
 
 
===Item 194 [at 1.1.1 Model Nomenclature Changes/0.0] (B A-S) 0/0/0===
 
=====Voter Comment=====
 
Please align RIM terms to reflect CPP usage or delete from CPP until aligned
 
=====Disposition & Disposition Comment - "Persuasive with mod"=====
 
Will CONTINUE to do BEST to keep CoreP aligned with RIM.

===Item 15 [at 2/2.3] (B M A-S) 0/0/0===
 
=====Voter Comment=====
 
Remove the word most; does the methodology really support just a RIM construct with no additional constraints?  I suppose it does; but does that make sense?
 
=====Disposition & Disposition Comment - "Persuasive"=====
 
 
 
===Item 16 [at 2/2.3.1] (B M A-S) 0/0/0===
 
=====Voter Comment=====
 
Why non-optional?  Isn't title an optional attribute (I wonder that someone following the example, and looking up the values in the RIM would mis-understand)

===Item 18 [at 2/2.3.2] (B M A-S) 0/0/0===

=====Voter Comment=====
 
I'm not familiar with this term as an XML term.  XML uses complex types and simple types.  (And we care about attribute types just as much as element types)
 
=====Disposition & Disposition Comment - "Persuasive with mod"=====
 
Change to: "In XML-encoded communications, the content model is either a "complex type" or a "simple type."

This (and the three later items (36-38) fall under a Negative Ballot reconciliation in which we agreed that McKenzie and Grieve would work to resolve these issues.

Modify your change to: "When source and destination systems share sufficient information to permit it, the source system may simply refer to an object rather than providing full details of the object. Rather than updating the object in either snapshot or update mode (see Update Control), the destination system should use the information provided to identify an existing instance of data."

=====Voter Comment=====
 
What are the brackets for?  Suspect the intention had been for this to be a link to "Expressed Model", though that raises the question of how to use updateMode when the expressed model is the RIM.  (The RIM doesn't explicitly expose any of the update modes as 'available for use'.  That's expected to be done in downstream models.).  There's a similar double-bracket thing a little further one that should be fixed as well.

This section appears to have nothing to do with the model designer.  And a good chunk of it is relevant to implementers, not just designers.

==Review/Update MnM of Project Scope for SAIF Artifact Definition==
=====Voter Comment=====

We reviewed the document that had been updated by Lloyd. This was the version that had been discussed previously in a joint conference call with Project Services. Minor edits were made to the document in clarifying the scope and responsibilities.  The [http://gforge.hl7.org/gf/download/docmanfileversion/6174/8092/SAIFArtifactDefinitionProjectScopev03.doc Revised PSS has been posted] and will be forwarded to TSC for its review.

ITS Work Group is preparing to advance a Project Scope for a project to:
=====Disposition & Disposition Comment - "Persuasive"=====
+
:"This project will develop ITS specifications for HL7 v3 messages and documents, that are wire-backwards-compatible to existing ITS Structures R1.1, and abstract data types R2 while to the maximum extent possible adopting all changes and new features that are being introduced by semantic and abstract specifications, such as the RIM and abstract data types..."

===Item 137 [at 6/1.8] (B A-T) 0/0/0===
+
The version reviewed was not believed to be the final version, but it is expected that this may come up for review in the Foundation And Technology SD before the next MnM meetingThere were lively discussions about the project and its intentions.
=====Voter Comment=====
 
This maybe one possible statement clarifying the existing text. Regardless the title and the content are not congruent, as the text gives an example of how do an override.
 
=====Disposition & Disposition Comment - "Persuasive"=====
 
I prefer this wording, tooIt also corrects the items negative voted in other votes.
 
  
===Item 182 [at 6/2.2] (M A-T) 0/0/0===

Based on the group's understanding of the proposal, the following major concerns were raised, and the co-chairs were urged to raise them in discussion at the SD:

*It is our understanding that there are elements of the proposed ITS that will '''not'' be backwards compatible, what are they, and how can one claim this is backwards compatible?
  
==Adjournment==
+
* We believe there is a need to '''limit''' this to those circumstances where there is an '''extant, demonstrable implementation of the earlier standard that justifies such backwards compatibility'''.  It should never be used for new, unrelated endeavors.

Plan response to ITS Project Proposal for Data Tapes ITS R2B

ITS Work Group is preparing to advance a Project Scope for a project to:

"This project will develop ITS specifications for HL7 v3 messages and documents, that are wire-backwards-compatible to existing ITS Structures R1.1, and abstract data types R2 while to the maximum extent possible adopting all changes and new features that are being introduced by semantic and abstract specifications, such as the RIM and abstract data types..."

The version reviewed was not believed to be the final version, but it is expected that this may come up for review in the Foundation And Technology SD before the next MnM meeting. There were lively discussions about the project and its intentions.

Based on the group's understanding of the proposal, the following major concerns were raised, and the co-chairs were urged to raise them in discussion at the SD:

  • HL7 needs to avoid sponsoring two incompatible "normative" ways to implement data types (DT) R2 (also the ISO data types) in the long term.
  • The complete capability of DT R2 should be the only viable target for the future, and relatively soon. The proposed ITS's do not strive to implement all features of DT R2.
  • If this is a bridge specification to allow a smooth transition, it should be sunset at some point.
  • It is our understanding that there are elements of the proposed ITS that will 'not be backwards compatible, what are they, and how can one claim this is backwards compatible?
  • We believe there is a need to limit this to those circumstances where there is an extant, demonstrable implementation of the earlier standard that justifies such backwards compatibility. It should never be used for new, unrelated endeavors.
