I have to cast my vote by 6th September 2004.
Please let me know if you as WG Chairmen have any comments against the following
Shall the CESG recommend to the CMC that the Proposed Standard "CCSDS
800.0-R-1 (draft), Reference Architecture for Space Data Systems" has
reached a sufficient level of maturity to be released as an Issue-1 Draft
Standard (Red Book) for formal Agency review?
Thanks

The Area Director for Systems Engineering wishes to publish the Reference
Architecture for Space Data Systems as an Issue-1 Red Book (Draft Standard) for
formal Agency review. Accordingly, a poll has been set up as follows:

Click on the poll: "RASDS ISSUE-1 RED BOOK" and cast your vote. In doing so, you
are reminded that the advancement from Draft Standard (White Book) to proposed
Standard is a major step. The criteria are expressed in section 2.3 of the
Restructuring document, and are summarized as follows:
CCSDS Draft Standard (Red Book)
Elevation to Draft Standard is a major advance in status, indicating a
strong belief that the specification is mature and will be useful. A second
explicit CESG and CMC approval action is required to move a Proposed
Standard to the Draft Standard level. A Draft Standard must be well
understood and known to be quite stable, both in its semantics and as a
basis for developing an implementation. It will generally go through
several "Issues" during which time it will progressively become more
mature. Every time that an Issue of a Draft Standard is published, it
automatically triggers a formal Agency review and the results of that
review must be satisfactorily incorporated before a new Issue can be
published. Since formal Agency reviews consume resources, a "review budget"
must be agreed by the CESG and the CMC prior to publishing the first Issue
of a Draft Standard; this budget identifies how many review cycles can be
consumed without re-authorization by the CMC. Each separate Issue must
clearly state the status of the specification and must indicate the risks
associated with implementing it in its current state.
At some point in the evolution of a Draft Standard that is intended to
result in a change to mission support infrastructure, at least one hardware
or software prototype (or other implementation) must exist which
demonstrates and exercises all of the options and features of the
specification in an operationally relevant environment, either real or
simulated. This point may be Issue-1, or it may be a later Issue depending
on circumstances, but for most documents the implementation must exist
prior to issuing a "final" Draft Standard. The WG Chair is responsible for
documenting the specific implementation(s) that qualify the specification,
along with reports relevant to their testing, or for justifying why such
implementation is either inappropriate or should otherwise be waived. The
documentation of the qualifying implementation must include clear
statements about its ability to support each of the individual options and
features. If patented or otherwise controlled technology is required for
the implementation, it must be demonstrated that the licensing process and
fees are fair and non-discriminatory
In its final stages of Issue, a Draft Standard is normally considered to be
a final specification, and changes are likely to be made only to solve
specific problems encountered. In most circumstances, it is fairly safe
for users to deploy implementations of the final Issue of a Draft Standard
into a disruption sensitive operational environment.
You are also reminded that in making this determination, your Area Director
approval role includes:
1. Making recommendations to the CESG for the progression of WG
documents as they approach key decision gates along the various
standardization tracks.
2. Ensuring that all Area work follows the set of architectural
principles agreed by the CESG and is properly synchronized with the smooth
evolution of the large installed base of CCSDS-compatible mission support
infrastructure.
Many thanks
Adrian
