MOIMS DAI WG Report

• DATA ARCHIVE INGESTION WG
• Goal Develop a CCSDS/ISO standard for a
  Submission Information Package (SIP) for transfer
  and validation of information submitted to an
  archive
• Goal Determine the need to update the OAIS
  Reference Model for the 5-year reviews
• Working Group Status Active __X_ Idle ____

MOIMS DAI WG Report

• 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

MOIMS DAI WG Report

• 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

6
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

MOIMS IPR WG Report

• 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

MOIMS NAV WG Report

• NAVIGATION WG
• Goal Development of standards for interagency
  exchange of data required for spacecraft tracking
  and attitude/orbit determination.

10
MOIMS NAV WG Report

• SUMMARY TECHNICAL STATUS Jan 2007 accomplishments
• Completed review / update of Working Group
  Charter according to 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 RIDs
  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 groups 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.

11
MOIMS NAV WG Report

• 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
• 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).
• Registration fees for big meetings?
• 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.

12
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 1st, 2007)
• A new message be added to the Orbit Data Message
  Standard, name to be determined.
• The message include elements of data from which
  canonical TLEs 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
• 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
• 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 TLEs be institutionalized at all?

13
MOIMS NAV WG Report

• 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 Release enhanced ODM version (Pink
  Book) for CCSDS review
• Summer 2008 Conduct prototype exercises
• Fall 2008 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
