Action Item responses.

140402-02)      SOIS schema compatibility to XTCE
There is a certain amount of ?compatibility? between some parts of these 
two schemas making conversion between an instance document in one to the 
other possible, even desirable.  The SOIS schema is partially based on 
XTCE.   However because SOIS is ?tuned? towards flight software and since 
XTCE is ?tuned? to ops, there?s some conceptual differences reflected in 
the syntax.  The part of each that has significant overlap is in regards 
to telemetry and command definitions ? although not all aspects of them 
are represented one to one between the two schemas.  For example, it is 
possible to convert a telemetry packet definition in a SOIS XML document 
to an XTCE XML document.  However, there are caveats.   It is known that 
there is not always a one to one mapping between FSW constructs and ops 
definitions of a telemetry packets at various institutions.  Typically 
these are ?header? areas or other items which involve ?bit level sub 
addressing? of a telemetry word in a telemetry packet definition.   For 
example at GSFC the Flight Software (FSW) may represent the CCSDS header 
in C using a ?struct? syntax perhaps with some bit-masks or something to 
that effect to get at ?bit subfields?.  On the ground however the various 
items in the CCSDS header may be separated out as individual telemetry 
parameters, even 1 bit parameters.   The two XML descriptions (SOIS, XTCE) 
would not be a simple one to one mapping.   Although, in some cases it 
would be.  Instead, a user with knowledge of their institutions ?way of 
doing things? should be able to write conversion tools between them. Some 
information in XTCE will not go into SOIS.  Example,  alarms are not used 
in FSW.  Likewise state machines describable in SOIS syntax would not be 
transferred to XTCE as it would not make sense to do so. For the main 
areas of overlap, the description the telemetry and command packets in FSW 
and XTCE conversion is possible.  It should be noted I do not know of  any 
significant effort in this area that has been undertaken to prove the 
concept, however GSFC is interested in this ?SOIS use case.?  No one has 
implemented such a conversion effort to date that Goddard is aware of.
 
140402-03)      XTCE 1.2
The OMG XTCE RTF (Revision Task Force) has been meeting weekly for several 
months to resolve the 1.2 issues.  The OMG XTCE issues database has 
accumulated 361 issues since 2008.  The effort is centered around 
reviewing, dispensing or accepting the issues. The  RTF has successfully 
gone through this process and captured about approximately 50 issues that 
will constitute XTCE 1.2.  The goal now is to produce a new schema with 
significant backwards compatibility to XTCE 1.1 while at the same time 
addressing the real issues that are effecting all users, to improve  XTCE 
so it is more usable and transferrable between parties, and with less 
customization needed.  Further the RTF has pledged to produce a public 
domain conversion tool from XTCE 1.1 and XTCE 1.2 this will greatly help 
the user community.   There is a candidate XTCE 1.2 schema that addresses 
all of the approximately 50 items.    It is still however being reviewed 
by participants and it is likely to change somewhat in the next few weeks. 
 The changes should at this point be minor.  There is a review period 
though September 2014 (OMG Quarterly Meeting in Austin, TX).  Then 
complete the required OMG documents (Change Form) for submission during 
the December 2014 OMG Quarterly Meeting.   A ?fall-back? schedule has the 
OMG documents submitted at the Spring Quarterly Meeting in Reston 
Virginia.   The goal is to produce in the same time frame the conversion 
tool.

Hi everyone, 

I would like to add a new agenda item to discuss "M&C Services RIDs". I 
propose that Sam distributes in advance of the WebEx any major outstanding 
issue. If need be we might then organise a dedicated WebEx. The updated 
proposed agenda (please provide any amendment) is now: 

1.        Approval of agenda and last MoM 
2.        Review of actions 
3.        Status of documents and prototypes 
4.        Agenda of next SM&C WG Technical Meeting
5.        CWE Schedule Update 
6.        Technology Binding Poll 
7.        M&C Services RIDs 
8.        AOB. 

Regards,
