The following standards are being developed by
ISO/IEC Joint Technical Committee 1 (JTC 1)
Information technology, Sub-committee 24 (SC 24)
Computer graphics and image processing, Working
Group 8 (WG 8) Environmental representation
WD 18023 SEDRIS includes SEDRIS DRM, Read
Write APIs, STF
WD 18024 SEDRIS Language Bindings
WD 18025 Environmental Data Coding Specification
(EDCS)
WD ????? EDCS Language Bindings
WD 18026 Spatial Reference Model (SRM)
WD ????? SRM Language Bindings
SC 24 standards go through the following stages
working draft (WD), committee draft (CD), final
committee draft (FCD), draft international
standard (DIS), and international standard (IS)
The US counterpart of SC 24 is the American
National Standards Institute, National Committee
for Information Technology Standards, Committee
H3 (Imagery and Graphics) (ANSI NCITS H3)

SEDRIS-Related SISO Products

In addition to the ISO/IEC standards development,
the SEDRIS program has been developing an
implementation of the SRM
A SISO product development group (PDG) has been
established to address technical implementation
of the SRM ISO/IEC standards
SRM Product Nomination Proposal (PN) was approved
by SISO SAC/EXCOM Feb 00
SRM PDG administrative meeting was held Mar 00
at SIW
SRM PDG is holding its first working meeting 5
May 00 at ANL
The SRM PDG will develop
Reference Product(s) containing formal comments
on the ISO/IEC draft SRM specification standards,
to be fed back to ISO/IEC SC 24 and WG 8 via SISO
and ANSI NCITS H3
Guidance(?!) Product(s) containing a SRM
reference implementation with detailed
specifications of all associated algorithms,
recommended usage practices, etc.

SISO Product Types

Standards Products Formally approved documents
that reflect consensus agreements on products,
practices, or operations, as required, by
simulation industry applications.
Interoperability with a SISO Standard shall
require full compliance to document
specifications.
SISO Standards are stable and well-understood,
technically competent, have multiple,
independent, and interoperable implementations
with substantial operational experience, enjoys
significant public support, and is recognizably
useful in some or all parts of the simulation
community.
Guidance Products Documents that can control the
development, integration, and use of common
reference data in some portion of the MS
community.
Similar to Standards in that they describe SISO
Best and Current Practices. A recommended
development process is an example of a Guidance
Product.
Reference Products Sources of information that
provide a passive input to models and
simulations. May also be an aid to research.
Include, e.g., reports prepared by Study Groups,
Data Dictionaries, Lexicons and the SIW
Proceedings.
Administrative Products Developed by SISO to
guide the operations and practices of the
organization.
Examples include the SISO Vision document and the
SISO Policies and Procedures.

PDG Operating Principles

The PDG shall be a world-class team that
satisfies the needs of the products community.
To accomplish this goal, it shall conduct itself
in accordance with the following basic operating
principles
Responsiveness and Responsibility - SISO shall be
responsive to the communities it serves. SISO
shall be responsible for providing products and
services that promote interoperability with the
least possible impact on existing applications.
Quality - SISO activities and resulting products
shall reflect technical excellence and the
highest quality work.
Discipline - SISO shall exercise due process in
all activities. Policies and procedures shall be
publicly available and shall serve as the basis
for governing the organization and its
activities.
Fairness - SISO activities shall provide the
right of appeal at all levels.
Openness - SISO activities shall be carried out
in an open forum where any person has access to
the process.
Consensus - SISO decisions shall be based on
simple majority agreement unless explicitly
stated otherwise. Votes and ballots may be
conducted in person, by teleconference, or by
electronic balloting, as appropriate, and as
established by the Product Development Group for
each balloted effort.

PDG Officers

PDG Chair The PDG Chair manages the PDG
organization and meetings, reports progress to
the SAC, and works with the Technical Area
Director (TAD, a member of the SISO SAC who will
oversee PDG operations) to ensure that the group
is responsive to the PDG nomination
PDG Secretary The Secretary assists the Vice
Chair and is responsible for meeting minutes,
consolidating reflector discussions, and posting
schedules and announcements
PDG Vice Chair (optional) The Vice Chair assists
the Chair and acts as the Chair when the Chair is
not available for PDG meetings or teleconferences
Note (The Vice Chair should also act for the
PDG Secretary when the Secretary is not available)

SISO PDG Election Process Guidance

"At face to face meetings and teleconferences all
present PDG members are eligible to vote. A
minimum of five person quorum is required to
conduct a vote. PDGs with restrictive
memberships may establish a minimum based on
percentage of members for SAC approval. A 75
consensus of present members is required to
approve a motion in a face to face meeting or
teleconference. If a 75 consensus can not be
reached the issue is moved to electronic vote.
The PDG secretary shall post a summary of the
discussion on the PDG reflector. After a period
for discussion, an electronic vote is held to
allow the complete PDG vote on the issue.
Electronic votes are carried by simple majority
(50 plus one) of ballots cast. The PDG Chair
and DG Editors may require an electronic vote of
any issue. Notice of an electronic vote shall be
posted 10 business days in advance and the voting
shall be open for 5 days.
Issues approved by 75 consensus at a face to
face meeting or teleconference shall be posted to
the reflector within 5 days. Members of the PDG
not present for the vote shall have 10 days from
the posting to recall the issue. Ten recall
petitions shall require an electronic vote. All
votes are subject to appeal to the SAC. Any
member of the PDG may appeal the result of a vote
to the SAC within five days of the posting of the
vote to the reflector."

Proposed Election Process

Self-Nominations on SRM PDG Reflector 24-30
April 00 None received
Self-Nominations at SRM PDG Meeting TBD?
PDG members present vote on the candidates for
Chair, Secretary, Vice Chair
Any candidate receiving at least 75 of the vote
is (provisionally) elected
Election results will be posted to the reflector
immediately following the meeting, and the 10
working day "recall period" will be announced
Unless a sufficient number (10, or more than the
number of votes received, whichever is less) of
recall messages are received within the recall
period, the results will be declared official and
sent to the SAC for approval
If no candidate for a particular office gets the
required number of votes (including the case
where a quorum is not achieved), or if there is a
successful recall, an electronic vote for that
office will be held
The electronic vote will be conducted by the
officers that were elected, if any, or by the SRM
TAD, if any, or by the SNE Forum Chair. Officers
will be elected by a simple majority of the PDG
membership (50 1). At the end of the
electronic voting period (15 days total), the
results will be announced and sent to the PDG
Chair for approval.

PDG Organization

Drafting Group - This group is responsible for
evaluating and evolving a draft product
circulating the product for review responding to
comments by reviewers and responding to the SAC
on scope, schedule, and technical issues. The
SAC establishes the number of drafting group
members based on the nature and expected activity
level of the group. This number normally ranges
from five to seven members. Drafting group
membership is assigned by the SAC.
Assigned Reviewers - This group is responsible
for concentrated review and comment on all
products, including interim products. There are
20 or fewer Assigned Reviewers. The members are
recommended by the Drafting Group and approved by
the SAC.
Volunteer Reviewers - This group is responsible
for overall review of the product. The Volunteer
Reviewers review any draft of the product and
provide comments to the Drafting Group.
Volunteer Reviewer membership is unlimited in
size and is open to the MS community and all
interested parties.

21
Drafting Group Organization

DG Editor The Drafting Group Editor is selected
from the PDG membership by the PDG Chair and TAD.
The DG Editor is responsible for developing a
component based on direction from the PDG. The
DG Editor assigns specific tasks to DG members,
collects input, and integrates it into the
component. The DG Editor reports the efforts of
the DG to the PDG.
DG Assistant Editor A PDG may select a DG
Assistant Editor for each component. The
Drafting Group Assistant Editor is selected from
the PDG membership by the PDG Chair and TAD.
This position is optional, but suggested by the
SAC for those products which are very large, or
very complex..
DG Member A DG Member provides input in the
development of the draft Product or Product
component. The default DG Membership shall be
the PDG membership. However, this may be
unworkable. The PDG may develop a narrower
definition of DG membership, and submit it for
SAC approval.
Assigned Reviewer Assigned Reviewers commit to
conducting a thorough review of the product.
Assigned Reviewers are drawn from the PDG
membership and are selected by the PDG Chair.
The Assigned Reviewers submit comments on the
Product to the DG.
