[CMC E-Poll Alert] CMC Poll Results

[Neil Dissinger]

CMC E-Poll Identifier: CMC-P-2006-07-003: Authorization to 
approve update to the Data Compression Working Group 
charter

Results of CMC poll beginning 23 July 2006 and ending 21 
August 2006:

                ADOPT: 3 (50%) (DLR, INPE, JAXA)
                ADOPT PROVISIONALLY: 3 (50%) (BNSC, CNES, 
NASA)
                REJECT: 0 (0%)
                REJECT WITH COMMENTS: 0 (0%)

      BNSC: I agree with Adrian's comments that we need a 
review of why the slippage was reported so late in the day 
in order to prevent a repetition.
      CNES: [Response added after poll closure, per e-mail 
date 22 Aug 2006]
Please clarify how the result of the CMC e-poll 
A-2006-03-001 closed on April 14, 2006 will be taken into 
account by the area and which interactions this may have 
with the activities planned in the new DC Charter, at the 
technical, schedule and ressource levels.
      DLR: [Response changed from "reject with comments" 
per e-mail dated 10 Aug 2006 . Original comments:]
- please finalze outstanding work.
- for new work items define a BOF to collect these new 
work items and define a workplan for the next 3 years.
      INPE: Concerning the document CCSDS 121.0-B-1, which 
currently corresponds to Standard ISO 15887 and, 
concerning document CCSDS 120.0-G-1, INPE wishes to 
observe that both mentioned documents resulted in a 
Brazilian ABNT National Standard, under number NBR 15063 
generated by ABNT/CB08/SC01/CE06, in May 2004. The NBR 
15063 standard document is naturally composed by an 
equivalent translation of the mentioned CCSDS/ISO 
Recommendation/Standard while also contaning as one of its 
appendices the equivalent translation of document CCSDS 
120.0-G-1. INPE wishes to recommend to CCSDS CMC that the 
CCSDS Data Compression Working Group may seriously 
consider the review of document CCSDS 121.0-B-1 Lossless 
Data Compression for a possible update that would clearly 
indicate in what instances this lossless algorithm could 
be tailored for, in the realm of space missions. Possibly, 
this desired, proposed action, at discretion of the 
mentioned WG, may also imply in the review of document 
CCSDS 120.0-G-1 in what may be considered to be pertinent. 
Unless it may be found by the pertinent WG that CCSDS 
120.0-G-1 should better be retired.
      NASA: The principal changes appear to be the 
introduction of a 1-year slip in the production of a Green 
Book and reference software. There's probably very little 
that can be done at this point to improve the schedule; 
however an analysis should be performed and a brief 
summary report to the CMC should be issued which defines 
exactly *why* the schedule slipped and why it took so long 
to update the charter to reflect the slippage. Without 
this kind of information, it will be difficult to manage 
future schedule-driven activities.
