Working Group Summary progress:



A list of issues with the draft Producer Archive Interface Standard
(PAIS) Red Book were reviewed and most were resolved. Updates
needed to the XML schema, for describing data objects to be
transferred to the archive, have been identified. Preliminary mapping
of PAIS / SIP attributes to the XFDU standard have been identified, but
completing this is the major technical work remaining. The outline for
the Green Book has been agreed.
Review of comments received on the need to update the OAIS
reference model have lead to a decision to do a minimal update to
clarify some terms and concepts.
Schedule (major deliverables only)



Draft PAIS Red Book, with Green Book, ready for formal review: 30 June 2007
Updated OAIS reference model, ready for formal review: 10 October 2007
Charter updated

CROSS-AREA TECHNICAL ISSUES

We will look to adopt guidance on XML schema expression as put
forward by the CCSDS XML SIG.
Other Issues and concerns

Registration Fees for meetings


Uniformly negative response
WGs

Allow individual WGs to meet as needed, at agency facilities, as long as they have
multiple agency participation. Perhaps hold Plenary every 2 years, and allow
cross-support meetings as needed, but encourage telecons, videocons
(e.g.,megameeting)
Resolution

In response to the 5-year ISO review of the OAIS reference model,
verify that we can put the updated document into ISO for review as a
final draft international standard (FDIS). If not, clarify what would be
the ISO document status

MOIMS IPR WG Report
Information Packaging and Registries (IPR) Working Group
The purpose of this Working Group is to:





Collect use cases from the space operations community and develop requirements
for XML data packaging:
Develop a set of recommendations that specify an extensible framework for
packaging data and metadata
Oversee the development of at least two implementations of the packaging
framework and associated with usability and interoperability tests in many areas of
space data systems
Based on testing experience and requirements from various Space Data and
Operations Groups, establish extensible registry / repository architectures that
leverage the more widely based registry work such as ebXML and UDDI.
Develop specific Registry/Repository standards that support the data packaging
registry/repository requirements focusing on the support of XML Schemas and
associated XML objects

ISSUES




IPR has received resource commitments from member agencies to develop
an XML Schema Registry Recommendation and implementations which are
needed both for XFDU deployment and coordination of the rapidly growing
XML schema volume within the agencies.
The IPR WG agrees that a common Registry / Repository Service
Architecture is needed within CCSDS and will provide full support for a
CCSDS wide effort to establish a preliminary version of this Architecture.
However, due to critical needs of IPR member agencies for an XML Schema
registry the IPR support of the Architecture effort is available for the period
from 1st Feb 2007 to 31st May 2007 at which time those resources will be
applied to the development of a CCSDS Recommendation for an XML
Schema Registry / Repository that specialize the CCSDS Registry/Repository
Service Architecture.
The resulting interfaces and data structures can then be used to
validate/modify the CCSDS Registry / Repository Service Architecture

current understandings
Completed review of ADM Red Book 1.4 updates and resolved a
number of open issues.
Completed review of TDM Red Book 2.0 early RID’s and a few open
issues.
Completed discussion of NDM/XML Red Book 1.2 and XML related
issues
Completed high level plan for the ADM Prototyping effort (GFSC,
CNES, JAXA)
Completed high level plan for the TDM Prototyping effort (JPL, DLR,
ESA)
Completed extensive and detailed discussions of unit discrepancies
in the group’s Recommendations (ADM, ODM, TDM)
Completed discussions with the ISO TC20/SC14 Liaison Dave
Finkleman and colleagues on the topic of standards for collaborative
operations in Earth orbit. ODM updates to accommodate these needs
are in draft status.

CROSS-AREA TECHNICAL ISSUES

XML Harmonization: More emphasis on harmonization of XML issues
across the CCSDS as a whole is highly desirable (e.g., common data
elements that pervade space operations). It would be good for the
XSG SIG/WG to address this in due course.
OTHER ISSUES AND CONCERNS

CCSDS Strategic Planning


Registration fees for big meetings?:


Better communication / coordination above and beyond the WG and Area are
needed (e.g., we have on several occasions experienced changes in
requirements –XML- that necessitated additional effort and caused delays in
documents).
Mixed opinion. The group felt that by changing the meeting schedule to a
single “combined Area” meeting per year, with the individual Areas meeting
one more time in smaller venues, the agency burden to support two meetings a
year could be reduced. The requirement for coordination between Navigation
and other Areas, as is facilitated by a large meeting, has been relatively low.
Scheduling of Meetings:

More flexibility for working group for arranging meetings would be good (1 big
/ 1 smaller & more flexible). A smaller Area-oriented meeting could better avoid
holiday weeks, reduce logistics issues, avoid working on Saturdays, reduce
weather risks, etc.

MOIMS NAV WG Report
ISO TC20 / SC13 + SC14 Collaboration
We are engaged in ongoing discussion with SC14 / WG3
regarding new requirements on ODM.


Discussions in these Winter meetings were collegial and positive. Several
agreements were reached, but there is still some internal resistance in WG.
Orbit Data Messages (ODM) updates to accommodate SC14/WG3 needs are in
draft status (Issue by March 15, 2007, Reviewed by April 1 st, 2007)





Risk: 2 competing standards for orbit descriptions between the 2 ISO
Subcommittees. Resolving the internal differences is a high priority.
Idea of TC20/SC14/WG3 suspending their effort on ISO/AWI 26885.TO DATE,
UNACCEPTABLE TO TC20/SC14
SC14/WG3 Liaison still lists the following outstanding issues:



A new message be added to the Orbit Data Message Standard, name to be determined.
The message include elements of data from which canonical TLE’s may be constructed.
The message include a 6x6 covariance matrix abstraction.
Metadata include covariance solve-fors, but values beyond the 6x6 abstraction need not be
provided
Information that cannot be described precisely enough be included in
optional fields and not in normative requirements
Should there be two additional message types in 22644 or just one?
Should there be one standard, ISO 22644, or two mutually consistent standards, one
emphasizing content and the format for that content, the other emphasizing elements of
information?
Should TLE’s be institutionalized at all?

ISO TC20 / SC13 + SC14 Collaboration - Conclusions






CCSDS Nav WG is following the Activity Plan developed cooperatively
with the SC14/WG3 at Rome in 2006
Good progress is being made
Some issues which must resolved remain, thus technical
collaboration should continue
Multiple standards for orbit data description are not in the interest of
SC14, SC13, the ISO overall, or the potential user community
(agencies and other satellite operators)
Current ISO Standard for orbit data description is ISO 22644, Orbit
Data Messages; it is being modified by the Nav WG to accommodate
SC14/WG3 requirements

Spring 2008


Summer 2008
Fall 2008
Release enhanced ODM version (Pink Book) for
CCSDS review
Conduct prototype exercises
Establish and publish enhanced ODM Blue Book
ISO/AWI 26885 work should be suspended, freeing the SC14/WG3 to
work on the many other elements of their Technical Program
