[CESG] RE: [Secretariat] SEA-R-2011-03-001 - Information Systems Architecture Working Group

[Hooke, Adrian J (9000)]

Peter: I would propose the following -


1.      We should first dissolve the current IPR-WG and IA-WG, since they have both been ineffective at meeting their chartered goals.

2.      You should ask "the International Planetary Data Alliance (IPDA) and other interested parties" to submit a formal request to CCSDS to charter this WG. Ask them to indicate their need, why they would like CCSDS to do the work, their community representation (which agencies and organizations they represent) and also to state their willingness to financially support the engineering operations of the new WG on the delivery schedule that is proposed.

3.      When we have that information we can weigh the technical benefits to CCSDS. Questions that will need to be answered include why this should be a global standard (when it appears to primarily represent the needs of the planetary science community) and if it truly is "cross cutting infrastructure that is applicable in a broader context than just mission operations", then how will the needs of other space mission disciplines be represented?

4.      After all of that is answered, we can pose a question to the CMC to see if they will be willing to sponsor an activity that primarily seems to come from outside CCSDS. While we in principle should be receptive to these kinds of requests, new WGs consume Secretariat and meeting space resources and the CCSDS benefits need to be weighed against the cost.

Best regards
Adrian

Adrian,

The IA WG has been working at a low level of effort, but in collaboration with the IPR WG, for some time now.  As far as I can tell the IPR WG appears to be on hiatus and we suggested at least two meetings ago that they both dissolve and apply their joint resources to this new activity.  I understood that there was general support for that approach.  I will propose that the IA WG dissolve once this new WG is approved.  I hope that MOIMS will do likewise with the IPR WG to free up the resources to work on this jointly in this new venue.

The IPR WG had focused upon an XML registry, which is a specific type of registry.  The IA WG guys have focused upon the overall information services architecture, including registries and repositories and how they may be specialized and deployed to build SOA style architectures.  They have a draft White Book that is now being circulated among the IA & IPR WGs, and also to members of the International Planetary Data Alliance (IPDA) and other interested parties.   The combination of all of this, along with a set of formal approaches for building interoperable SOA-style framework is what this work is all about.  This could presumably become an IPDA standard, but that group does not now have a standard making function, so it is preferable to house it within CCSDS.

At this point, as you are aware, this effort in NASA is being funded not by SCaN but by SMD.  There are similarly funded efforts in Europe and they are part of this IPDA effort that appears to be making good strides toward agreeing on a common information systems architecture approach.  A lot of this leverages work that has been done in the very successful Planetary Data System (PDS) that Dan leads.  That existing operational system is now in the process of being updated, and all of this is using the as yet draft, but quite useful, products of the IA WG.  There appears to be good synergy within the group and valuable contributions from various European efforts and from other communities of interest like astronomy.

Once there is feedback on the draft White Book we will be in a much better position to address the issue of resources and where they are coming from.

The simple answer as to why do it in SEA instead of MOIMS is that this is cross cutting infrastructure that is applicable in a broader context than just mission operations.  There is no question that this needs to be coordinated with MOIMS SM&C, and initial coordination and discussion has already been taking place in CCSDS for at least the last few meetings.  Furthermore, we have been coordinating closely for the last few months within NASA, between the JSC MOD folks and the PDS team here at JPL, to do a prototype of the ISA framework running on top of the MAL and providing the SM&C specified Directory Service.

Separate from this there is work within JPL to apply this same technology to the DSN DISA service, which is a network operations focus instead of mission operations focus. This is, as I said, cross cutting infrastructure.

Best regards, Peter

Peter: it's not clear how this proposed new WG relates to the current Information Architecture WG. Could you please clarify?

According to the management framework, the current  IAWG was chartered in 2007 and was supposed to produce a Magenta Book in 24-months:
http://cwe.ccsds.org/fm/Lists/Projects/DispForm.aspx?ID=105&Source=http%3A%2F%2Fcwe.ccsds.org%2Ffm%2FLists%2FProjects%2FAllItems.aspx

However, almost 40 months of work later it still does not appear to have produced even a White Book. This new (additional?) working group proposes to go from zero-to-two-Magentas in about 18-months. Do you have a plan for how this will be accomplished? Who are the participating Agencies? Who has committed resources to do the work? Finally, why is appropriate to do this work in SEA rather than in MOIMS?

Best regards
Adrian

SEA-R-2011-03-001

The System Engineering Area,

CONSIDERING that the INFORMATION SERVICES ARCHITECTURE (SEA-ISA) BIRDS OF A FEATHER has produced a charter for their proposed working group; and

RECOGNIZING that CCSDS A00.0-Y-9 section 4.2.4.3 requires the Area Director to recommend chartering of working groups for approval by the CESG, therefore

RESOLVES that the draft Information Services Architecture WG Charter be reviewed by the CESG, and

RECOMMENDS that the CESG approve this Charter so that this Working group may be formalized, and finally

REQUESTS that a CESG poll be conducted to accomplish this.
