AREA REPORT

1. Data Archive Ingest (DAI) WG

Working Group Summary progress:• Use Case Guidelines for applying approach described in

draft WB “Specification for the Formal Definition and Transfer Phase of Producer-Archive Interface” (SIP standard) generated

• Use case for SIP submission of data to National Space Science Data Center (NSSDC) generated

• French translation of “Reference Model for an Open Archival Information System (OAIS)” ready for CCSDS and ISO approval

Problems and Issues:• No information on status of ISO review of PAIMAS at this

time• No response from CMC on request for clarification on how

to get French translation of OAIS Reference Model recognized by ISO

AREA REPORT

Information Packaging and Registries (IPR) Working GroupWorking Group Summary progress:• XML Formatted Data Unit (XFDU) - Structure and Construction Rules

White Book Version 2.0 approved by CESG as a CCSDS Version 1 Redbook• XFDU Toolkit, a reference implementation of above standard, has been

updated to include schema changes and enhancements included in the new version of the Recommendation

• Several telecons with Digital Library and Video Streams(MPEG ISO) on aligning XFDU,METS,MPEG21. See ISO request for liaison

• JPL successfully used XFDU Toolkit libraries to create Packages for Servers in the DSMS prototype

Issues:• The inclusion of various “advanced” features in the XFDU Version 2

Redbook will be based on the status of agency prototypes and agency priorities discussed in the IPR WG meeting in Athens

B. SUMMARY TECHNICAL STATUSAREA REPORT


GOAL 1 - ON-GOING : to produce a SM&C Green book• Submitted to CMC on 23Sep04. Update incorporating agreed

comments to be re-submitted to CMC in April 05

GOAL 2 – ON-GOING : to specify and produce the Red Books for the following services as the baseline for further specification:

• SM&C Protocol (JPL), SM&C Common Services (ESA), SM&C Core Services (ESA)

• Draft red books available and under internal review

GOAL 3 – ON-GOING : to update the XTCE standard with the result of the public review together with the OMG• XTCS CCSDS agency review closed 31Mar05 (ALL)

• 80 RIDs raised (BNSC=34, DLR=16, ESA=24, JPL=6)

GOAL 4 – ON-GOING : to specify the other high level services identified in the Green Book. Work has started on:

• SM&C Time Service (CSA), SM&C Remote SW Management Service (LogicaCMG), SM&C Automation Service (CNES)


SUMMARY TECHNICAL STATUSAREA REPORT


Problems and Issues:

• Relationship with OMG• Potential overlap between SDTF and the SM&C work• Boundary and conditions of collaboration not clear

• ESA financial contribution to SM&C for 2005 not promising

• Resources for prototypes development (for 5 RBs)• Priorities will be set up next week


C. CROSS-AREA TECHNICAL ISSUES

AREA REPORT

Information Packaging and Registries (IPR) Working Group

• Issue 1 - The IA and IPR WG chairmen agree that a Registry / Repository task is urgently needed within CCSDS. They also agree that the task should be under the MOIMS area either as a separate WG or in the IPR WG. The IPR WG has reserved time for a joint IPR/IA session on Registry/Repository during the Athens Workshop to discuss this issue

• Issue 2 - The SANA BoF chairman agreed to revise the proposed SANA WG charter to focus on Web Interfaces and the collection and presentation of numbering and identification information in existing CCSDS documents to provide a one stop shopping site for this type of information. This should eliminate any conflict with the IPR


D. OTHER ISSUES AND CONCERNSA. Issue 1 CMC should respond to the Liaison request from

ISO/IEC/JTC1/SC29/WG11 CODING OF MOVING PICTURES AND ASSOCIATED AUDIO INFORMATION(MPEG) included as next slide

AREA REPORT

INTERNATIONAL ORGANISATION FOR STANDARDISATIONORGANISATION INTERNATIONALE DE NORMALISATIONISO/IEC JTC1/SC29/WG11CODING OF MOVING PICTURES AND ASSOCIATED AUDIO INFORMATION

ISO/IEC/JTC1/SC29/WG11/N7009Hong Kong, January 2005

Source: ConvenorTitle: Liaison Statement to CCSDS Panel 2

WG11 (MPEG) was made aware by some of its members about your work on the standardization of XMLFormatted Data Units (XFDU) aimed at “representing widely applicable XML-based packaging techniques,,covering both wholly XML data as well as XML data with binary data leaves”.

WG11 would like to point out that its work on MPEG-21 DID (ISO/IEC 21000-2) might be relevant in the context ofCCSDS’s work on XFDUas both standardization efforts aim at defining an XML-based format that can be used to ‘package’ several assets and their metadata in a single container structure.

Within the MPEG-21 framework, such an XML data structure is called a DIDL document. The asset represented by the DIDL document is referred to as a Digital Item. MPEG-21 DID takes care to specify the declaration of Digital Items inmainly two normative sections:

An Abstract Model: A set of abstract terms and concepts that, together, form a well -defined data model for declaring Digital Items. The Abstract Model allows for Digital Items to be represented in many ways. Currently MPEG-21 DID defines a normative XML representation of Digital Items based on the Model.

A Representation of the Model in XML: The description of an XML syntax for each of the entities defined in the Abstract Model. This XML-based syntax is referred to as the Digital Item Declaration Language (DIDL).

The first edition of MPEG-21 Part 2 was published as an ISO standard in March 2003. A second edition is currently beingfinalized and will mainly enhance the functionality of the DIDL.

We are looking forward to a fruitful collaboration.
