1. Call to order

The meeting was called to order by the chair, Valerie Shuman, at

9:05 AM EST.

2. Introductions

The chair asked everyone to introduce themselves.

3. Appointment of Acting Secretary

The chair asked for a volunteer from the working group to serve as secretary. There being no volunteers, the chair asked Charles Herget to take the minutes of the meeting.

4. Approval of Minutes

There was a request to approve the minutes of the previous meeting

on November 8, 1996. The unapproved minutes were posted on the IEEE

Standards web site:

http://stdsbbs.ieee.org/groups/scc32/scc32-minutes.html .

It was noted that some of the attachments referenced in the

minutes were not available on the web. Rosemary Tennis said that

she had not received all of the attachments in electronic form so

they could not be posted. Tennis made a request for everyone to

provide their presentations in electronic form as well as paper.

There was a motion (Barrett) made and seconded (Schoka) to approve

the minutes as posted on the web. The motion was accepted without

objection.

5. Approval of Agenda

An agenda was distributed and a request for approval was made.

There was a request to add a presentation by the EPA on the use of

their data base. There was also a request to add a presentation on

the Traffic Management Data Dictionary under New Business.

The agenda (Attachment 1) was approved as amended without

objection.

6. Consultant Progress/Issues Report and Discussion

It was announced that Ontek Corporation had been awarded a

contract by the IEEE under funding provided by the Federal Highway

Administration to provide consulting on this standards effort.

A presentation on the status of the contract was given by Tony

Sarris of Ontek. (See Attachment 2.)

7. EPA Environmental Data Registry

Bruce Bargmeyer gave an overview and status of the EPA's

Environmental Data Registry. (See Attachment 3.)

Joe Leahy gave a demonstration of the use of the registry which can

be accessed at

http://www.epa.gov/edr.

A demonstration is also available at

http://www.epa.gov/eimde/html/test/test.html.

Shockwave is required to use the demo and can be downloaded from this site

8. Discussion on Ontek presentation

The group was asked to turn to discussion on the presentation by

Tony Sarris.

Bruce Eisenhart asked how the proposed approach solves the ITS

problem, Should there be one central registry for all ITS data

versus a registry for interchanged messages? How are existing data

dictionaries and new data dictionaries under development

incorporated?

Tom Kurihara suggested that there should be a concept of

operations. Issues to be addressed include:

A Central Registry

Common vs. Specialized data

Global vs. local uses of the data

Authority (data ownership and stewardship)

Distribution

Enforced standardization

Uses of the data (e.g. statistical analysis, reporting, control,

business/financial accounting, etc.)

Shuman asked for volunteers to draw up "concept of operations" ideas

from the ATIS (Advanced Traveler Information System), APTS (Advanced Public Transportation System ) and ATMS (Advanced Traffic Management System ) perspectives.

Lyle Saxton, Paula Okunieff, and Bob Barrett agreed to assist.

9. Interim Data Registry

Discussion began on the need for an interim registry for use prior

to the adoption of the standard.

Saxton said he thought that an interim registry was desirable and

needed.

A motion was made (Barrett) and seconded (Okunieff) that the

interim registry accept structures in ISO 11179. The motion

carried with one abstention (Jaffe).

Bruce Eisenhart gave a presentation on a proposed interim registry

to be implemented by the Architecture Team using Microsoft Access.

(See Attachment 4.)

Schoka had reservations about endorsing a quick interim registry.

He stated that there were already models developed by the EPA and

Bellcore based on ISO 11179 that could be followed.

A motion was made (Saxton) and seconded (Okunieff) that the

Working Group support the proposal by the Architecture Team to

provide service to the data dictionaries under development.

The motion passed with one dissenting vote (Schoka).

Shuman requested a one page overview of the exact goals and

outputs of the interim registry. Eisenhart agreed to provide this

overview within one week.

Parker asked the question, "Will there be one registry or more than

one registry?"

Questions were raised regarding a central registry.

Will it be at one physical location or will it be central in a

logical sense? There seemed to be agreement that central meant

logical rather than physical.
