[Ccsds-omg-liaison] Evolution of XTCE

Mario makes some important points. The first item of business is to deploy 
the current version of XTCE and that involves putting in place some tight 
configuration and audit controls so that any bugs that are discovered by 
users can be reported and dispositioned in an accountable way. I'd very 
much like to see the SDTF address these issues and come up with a plan for 
a formal mechanism for change control and evolution.

Also, I'd be grateful if such discussions could be CC'd to the CCSDS-OMG 
LIAISON mailing list <ccsds-omg-liaison at mailman.ccsds.org> rather than just 
the OMG list.

Best regards

Chairman, CCSDS Engineering Steering Group (CESG)

>Hi Brad,
>I see what you are after, although it seems to me that the topics in the
>agenda are certainly premature and have to my ears some negative connotation:
>hopefully we will come at the end of this month with XTCE approved and you
>are already working for changing it!!!!
>I know, I am exaggerating, but be careful that the user community is quite
>conservative and they want to embark on new things only if they are stable
>enough. They do not like moving targets ... but I guess you know this.
>I would suggest that you re-phrase the agenda points to give more a feeling
>of stability still obtaining the same results. For instance, we might propose
>to set up a feedback system (by the way, this is a request from NASA via
>CCSDS) where different missions or users can submit feedback. Additionally,
>the envisaged XTCE penetration strategy could also be presented:  initially,
>organisations could build (or re-use, if available) translators (proprietary
>DB format<->XTCE) so that legacy systems do not need to be modified; in a
>second stage, legacy systems could be modified to read and write XTCE
>directly. Finally, as suggested already by Kevin, it would be good if we
>could test the user community for the need of XTCE tools (e.g.
>translators).Experience tells that a standard has a higher likelihood to
>become successful if tools (hopefully free of charge) are available.
>I hope it helps.
