Valerie Shuman, Chair
1. Call to order
The meeting was called to order by the chair, Valerie Shuman, at
9:05 AM EST.
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:
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
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
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
A demonstration is also available at
Shockwave is required to use the demo and can be downloaded from
8. Discussion on Ontek presentation
The group was asked to turn to discussion on the presentation by
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
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)
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
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
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.
Other questions were the following.
What is it?
Where is it?
Who operates it?
Who pays for it?
Who decides the content and on what basis?
What tools might be used to support its creation and on-going
Shuman asked Parker to write a white paper giving the pros and cons
to the two sides of his question.
Parker agreed to write the white paper and distribute it to the
working group within one week. He asked for comments back to him
within two weeks after distribution of the white paper so that he
can summarize the results. See White Paper: DATA REGISTRATION OPTIONS
10. User requirements
Shuman asked for input from three of the users on what they
perceived as the concept of operations for the data dictionary as
described above in 8: Saxton for the Traffic
Management DD, Okunieff for the Advanced Public Transit System DD,
and Barrett for the Advanced Traveler Information Systems DD.
Each prepared a view graph summarizing his or her views.
See Attachments 5.
11. Glossary Progress Report
Schoka is leading the effort on terminology. He passed out an Email
message he had sent the working group and a response he received
from Paul Hawes (Attachment 6). He asked for comments in one week
and then he will synthesize the results in to a next draft to be
distributed the following week. See Candidate ITS Working Terminology for Data Dictionaries and Message Sets
12. ISO TC204 Request for Review
Shuman said that she had received three documents from WG 1 of
ISO/TC 204: N222, N223, and N224 (See Attachment 7). Copies of the
documents were passed out to the Working Group with a request for
comments by February 14. Comments should be sent to Roy Courtney.
Schoka provided an overview of these documents. The primary
material is the identification of classification schemes. Layer 1
identifies ITS and layer 2 level identifiers are based on TICS user
NOTE: Recent events in ISO have overtaken these documents. A formal
report of the ISO activities will be circulated as soon as it is
Shuman requested volunteers to serve on a subgroup to work on
classification schemes. Bob Barrett, Bruce Eisenhart, Paula
Okunieff, Tony Sarris, Lyle Saxton, and Andy Schoka agreed to
serve on the subgroup with Eisenhart as chair.
13. Request for officers
Shuman said that the positions of vice-chair and secretary of the
working group were open and asked for volunteers.
Sarris asked if we needed to be concerned with syntax in the body of
the message, e.g. should we use ASN.1 to express data in the message
or will this be addressed at a lower layer in the ISO OSI
Shuman said she felt that we needed more information on ASN.1 and
asked if someone would give a presentation at the next meeting. Tom
Kurihara volunteered to present issues for discussion at the next
