1. djc -1 Daniel J. Crichton Dan.Crichton@jpl.nasa.gov NASA/JPL 9 May 2006 CCSDS Information Architecture Working Group

2. djc -2 IAWG Charter The focus of this working group is to define a reference Space Information Architecture that encompasses the capture, management and exchange of data for both flight and ground environments across the operational mission lifecycle. Goals: 1. Define a reference end-to-end space information architecture for interoperability and cross-support that encompasses both flight and ground data system operations and provides a common framework for use by standards and systems developers. The reference space information architecture includes: a. standard functional components for information management b. definition of standard interfaces for information management c. standards in information representation d. standards in defining information processes 2. Define and leverage common methods for representing information architectural views; and 3. Address application layer information management issues including application protocols and data handling and ensure that they are dealt with in a clear and consistent way throughout the end-to-end system; and 4. Work with the SEA System Architecture and MOIMS WGs

3. djc -3 Deliverables Information Architecture (RASIM) - Status: draft Green Book, under review by agencies - Incorporated comments from NASA & CNES from March 2006 version - Latest version sent out in June 2006. - Publication: Update based on comments and review in Rome. Publish as a green book after the meeting. Benefits - Separation of the data and software architectures - Identification of core information services - Movement towards standards for each of the components/services - Provide agency interoperability at the data level - Leverages COTS-based architectural model (E.g. service- oriented/grid architectures) - Leverages other standards efforts/concepts IAWG Work Overview

4. djc -4 Status of WG Information Architecture draft Green Book – June 2006 Version Tightening of the model and concepts Alignment with other standards Integration of cross agency comments Ontology developed based on white book. Captured in Protégé IA/IPR working together on a planning XML-based information services starting with XML schema registries Working with various NASA groups on adoption
