at x:10 we did not have quorum and proceeded informally

2.  Acceptance of minutes from previous meeting - deferred due to lack of quorum.

3.  Adoption of agenda/schedule planning.  Adopted

4. Review priorities and assignment of work items (Mavis/Lisa/Mark)

Mavis helping Gunter with common core components document.  Have chunked this document out to 9 people with due back to Mavis on 3/10.  We have gotten a lot of comments back from Garrett indicating that there is a divergence between Op70 and CCTS version 1.9.  Some general discussion on this issue.  Ann read one comment and the sense of the group was that we have the issue covered, but we may not have it well explained in the release package. 

Gunter asked the question regarding representation terms (primary and secondary)  and core component types.  There appears to be some confusion and Gunter needs to make more clear the association and identification of primary and secondary representation terms and CCTs.  Gunter will put in additional documentation.

5. Review NDR release schedule (Mark)

Mark has received only the input from Bill.  Others still

Local v Global			Waiting on report from Jim
ModNamVer			Bill has submitted
Core Components		Gunter and Mavis have paper in progress.  Due next week
Embedded Documentation	Group has made decision.  XHTML is decision.  Mavis to write narrative to support rule.

There was some discussion surrounding Gunter's embedded documentation paper and how to post.  Gunter will ensure that XHTML option is included and that the decision of the NDR to use XHTML is included as an editorial comment.  Mavis will review, edit, and post.

6. Review Code list output (Lisa)

Lisa has sent material to list.  Has seen Eve's email posted today, but has not followed through with it.  Lisa will pursue.  Eve thinks that the UN/ECE is moving in our direction and is close to what we need but we still need to work with them to really adhere to what we are doing and to come to agreement on what attributes (see Gunter's paper) are needed for well known code lists as opposed to what attributes are required for lesser known code lists.  Lisa and Arofan need to look at what Eve has sent out and compare with CCTS 1.9.  Eve and Lisa and Arofan will have a call on Monday to discuss and will have updated paper by mid next week to share with UN/ECE and ATG2.

7. Updates on status of Local vs. Global (Jim)

Jim has submitted report that only one comment was received.  Mark stated that procedurally there does not appear to be support for reversing the decision.  Jon raised an issue that we did not give sufficient time for the discussion and he can't believe that people don't have an opinion.  Eve stated that she does have some thoughts, but they are not to reverse the decision, rather to take advantage of opportunities to improve the process for defining the names and improving the pearl script.  Eve will look at the paper in more detail.  We will extend the comment period until Monday the 17th.  Lisa will send announcement to UBL listserve indicating that comment period is extended.

8. Containership (Arofan)

Arofan has three problems with the existing release 1) there may be some processing concerns with some built-in inefficiencies in how the library is structured 2) if not neatly encapsulated, then it is difficult to understand and there may be binding issues 3) with the containership as it stands, if we try and extend using the context mechanism, we have insufficient containers to add header type of field and so would have to add after all of the line items.  Eve says that we discussed 3 in our original containership discussions, but we have said that if we normalize, if we use real semantic basis, then adding to the end does not cause a problem since they are related to the parent.  But the actual performance issue may mean that we need to revisit.  Eve agrees that we never reached formal agreement on containership and that in October we felt that we were in general agreement with the LC approach, but we reserved final judgment until after we looked at the Op70 release.  Arofan does not think these containers are a semantic function, but a design function.  Arofan has two proposals: 1) Do we artificially insert a header and body container (not proposing a summary container) and 2) when we have lists of like things, for performance reasons and encapsulation reasons do we have a container that wraps around them - i.e. list containers.  Arofan feels these are the points where LC normalization breaks down.  Eve thinks there may be semantic issues.  Eve 
might support more containers if done smartly.  Mark asked if we can define clear rules that would ensure consistent LC approach.  Arofan feels it can.  Mark asked if Arofan would update paper.  Arofan proposed alternative in which he would write specific rules and supporting narrative.  Mark asked Marion if he thought we should have discussion with LC.  Marion said we should do on listserve.  Arofan does not think it is LC issue.  Eve suggested that Arofan update paper, NDR review and discuss on next weeks call, and then if we agree with Arofan's proposal we then enter into discussions with LC to determine if they have any pushback.  Arofan to have paper out by end of week and we will discuss on next weeks call.

9. Polymorphism Resolution 

Eve is not sure that what we are talking about under polymorphism is really inheritance.  Mark wants to know how to discuss in NDR document.  Matt is supposed to be providing some words that describes this for inclusion in the ModNamVer paper.  Mark query Matt and Bill to see if this has happened.

10. Administrative Matters

Portal Update - Lisa to ping Mavis to get portal up to date.
Membership Status - two prospective members.  Mark to raise issue on chairs list:  two people are they voting members.

11. Other business.  None.
