Judith Newton chaired the meetings.

 

Prior to the meeting, Judith sent an agenda with links to the major documents to be discussed. She also sent out messages with information necessary for attending the meeting via conference call. A teleconference bridge was available each of the meeting days for national and international dial-in calls. All persons, from any country, who are interested in the projects, are invited to call during the meetings. Anyone from outside the US, who wants to call in, should send a message to Judith Newton (jnewton@nist.gov) or call her at +1 301 975 3256 so that any special arrangements can be made. We can phone out to international parties, who wish to participate in the meeting. For example, we originate the call to Joe Christensen at his home, in the middle of the Australian night, so that he can participate.

 

1. Agenda for WG 2 Santa Fe meeting

 

We discussed the agenda and some revisions were suggested. We are concerned that there is only three days of WG meetings and we want to get some real editing work done. The Open Forum on the previous week should bring delegates up to speed with the general information about each of the projects. It is hoped, therefore, that we can focus the WG 2 meetings on fairly substantive editing work. Ray Gates pointed out the need for an agenda for the editing meeting on the Part 3 revision. We will work on creating a draft. Bruce Bargmeyer will contact Tim Bourne to see if he wants to hold an IRDS editing session.

 

2. Web sites

 

Some work is underway on revising the SC 32 web site. There is some desire to share the web-site responsibilities and there are several offers of various capabilities. One thing that we need to do is to get the document numbers assigned to certain WG 2 documents. Australia did this for the required documents on the Australian WG 2 web site.  Since work is going on around the world, and people need to post documents during their work hours, we need to be able to get document numbers assigned automatically and to have a web-viewable document list. If Australia can do this, we would like to ask them to do it. If not, we understand that Canada may be able to provide such a service. Bruce Bargmeyer will inquire to see if  Australia or Canada can offer this service.

3. Open Forum

 

Arrangements are in place for the Open Forum on Metadata Registries, which will be held January 17 -21, 2000 in Santa Fe, New Mexico, USA. The web site for the Open Forum is: http://www.nist.gov/openforum2000 Registration is now open. The immediate action is for people to distribute the call for participation (and URL) to groups who may be interested in attending. Publicity for the Open Forum should be sent out quickly, so that potential participants have time to make plans. Several people agreed to send the call to various lists.

 

Standards committee members are urged to sign up early, since the block of reserved rooms may not be enough for all participants.

 

4. ISO/IEC Part 3 Revision

 

Most of the meeting was spent on the revision of  ISO/IEC 11179 Part 3. We went through the issues list and made proposed resolutions to several of the issues. Ray Gates and Doug Mann will edit the standing issues documents to reflect the issue resolutions proposed at this meeting.

 

A checkpoint version (as of October 1, 1999) of the standing issues documents, model, and revised Part 3 text are on the FTP server. We still need to get the checkpoint material for XML and for the conformance attributes.

 

To find the checkpoint material, FTP or point your browser to:

 

www.sdct.itl.nist.gov/~ftp/L8/sc32wg2/projects/11179p3r/checkpoint/19991001/

 

The documents are in that directory

 

To help people understand and read the UML diagrams, there is UML documentation at a couple places:

 

Ray Gates provided the OMG URL:

http://www.omg.org/cgi-bin/doc?ad/97-08-04

 

and Doug Mann provided a URL from Rational Corporation:

 

www.rational.com/uml

 

 

In addition to the checkpoint version, all of the project documents for the revision of Part 3 are available on the Internet. The individual issues/proposals are all combined into two standing documents. The first standing document lists brief descriptions of each issue in tabular form. The second standing document contains a compilation of the full information about each issue, including proposed resolution and status.

 

The WG 2 standing documents for this project can be found in a directory at the following location:

 

http://www.nist.gov/L8/sc32wg2/projects/11179p3r/standing-documents/

 

A document that contains a tabular listing of the identified issues for the Part 3 revision (in MS Word Format) is named:

wg2sd11a-issue-list-p3r-table.wd6.doc

 

A document that contains a tabular listing of the identified issues for the Part 3 revision (in HTML format) is named:

wg2sd11b-issue-list-p3r-table.htm

 

(The full URL for the above document is (note: you may have to put the URL together if your email system breaks it into separate lines):

http://www.nist.gov/L8/sc32wg2/projects/11179p3r/standing-documents/wg2sd11b-issue-list-p3r-table.htm
 
A document that contains a the full proposals for the identified issues for the Part 3 revision (in MS Word format) is named:
wg2sd12a-issues-list-p3r-documents.wd6.doc
 
A document that contains a the full proposals for the identified issues for the Part 3 revision (in HTML format) is named:
wg2sd12b-issues-list-p3r-documents.htm
 
Here is the full URL to get the HTML version:
http://www.nist.gov/L8/sc32wg2/projects/11179p3r/standing-documents/wg2sd12b-issues-list-p3r-documents.htm
 
Ray Gates will update the standing document issue files.
 
Participants are asked to review this material and suggest changes or revisions. Another checkpoint version will be created on December 1, 1999. This will be the version that is discussed in the January 2000 WG 2 meeting.
 
5. Changes to be made to other parts of 11179, due to the revision of Part 3
 
To respond to one of the Canadian proposals for the revision of Part 3, the editors of each of Parts 1, 2, 4, 5, and 6, should prepare a document describing the changes that need to be maid to their part. We would like to have these documents ready for the December 1, 1999 checkpoint version. The editors are requested to prepare a document for their part..
 

6. Content Consistency Technical Report

 

We discussed the "Levels of Abstraction" part of this document. Judith Newton has incorporated material with an object-oriented perspective. Upon discussion, it was agreed that Judith Newton, Tommie Curtis and Lois Fritts would work together on more fully incorporating the generalization - specialization concepts from Object-Oriented documents. This work will  apply the concepts to the refinement of general data elements as they are specialized for use in regulations, reporting requirements, forms, and information systems. The other material in the "Levels of Abstraction" section is more relevant to Part 3. Judith will remove it from the Content TR and we will consider how to incorporate it at appropriate places in the Part 3 text.

 

Lois Fritts will also extend the section on registering groups, with some guidance from Doug Mann on which structures in the current metamodel are to be used for this purpose.

 

7. Metadata Query Service

 

The New Work Item proposal is out for JTC 1 ballot. Further work on this project requires that the metamodel be stabilized.

 

8. IEEE Learning Technology Standards Committee (LTSC)

 

Frank Farance described the work of the IEEE LTSC. The work of this committee includes standards to enable the sharing of educational materials and learner information. A part of this work involves data semantics and formats. ISO/IEC 11179 is being used to support the maintenance of typing schemes. They have also made substantial use of ISO/IEC 11404, Language Independent Datatypes. There is a desire for collaboration between this effort and the work of SC 32/WG 2.   LTSC is developing APIs and XML bindings for its semi-structured data.  LTSC is requesting support/advice on its specification of data models.

 

A proposal will be made to create a new JTC 1 subcommittee to cover Learning Technology.
