[Ccsds-omg-liaison] Evolution of XTCE

Mon Sep 18 12:02:52 EDT 2006

The first item on discussion (tight configuration and audit control)
will be easy as the OMG has a will established, open and very
transparent configuration and and audit process for available
specifications detailed in the OMG Policies and Procedures.  A good
introduction to the OMG maintenance phase can be found here:

http://www.omg.org/gettingstarted/process5-Maint.htm

Highlights of this process: anyone can submit an issue, all issue
resolutions are voted on by the RTF, and RTF membership is reasonably
open.
The XTCE RTF is about to submit version 1.1 (the first revision of XTCE
after a year and a half of use).  Hopefully version 1.1 will also be
co-adopted by the CCSDS as a blue book specification.

I understand that other organizations ESA, CCSDS, Lockheed, etc. have
their own input process to the OMG issue database, but that process is
up to the feeder organizations.  We have had some extremely valuable
inputs from each of these organizations.

gerry

	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
	Adrian

		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.

agenda for Space DTF at  
		                                        Anaheim

		Mario,

		It is an open invitation for attendees to provide input
on the direction
		of XTCE in the future, e.g.
		1) When should we charter a new revision task force?
		2) What new areas should be tackled?
		3) Are there areas that need revising due to difficulty
in
		implementation?

		We will have just discussed XTCE in both the Space
Information Day and
		the XTCE tutorial on the prior day, so the expectation
is that a number
		of people will have had exposure to XTCE and therefore
generate an
		exchange of ideas.  I don't have any specific goals
except to capitalize
		on an opportunity to listen to the OMG membership.

		Thanks,
		Brad K.

		Brad,

		what do you plan to say for the agenda point:

		"XTCE Birds-of-a-Feather - What's next for XTCE?"

		Ciao
