  2. Overview • NASA/PDS and ESA/PSA have worked closely together to coordinate archiving activities for current missions (e.g., Huygens, Mars Express, Venus Express) • This has led to ESA PSA/NASA PDS collaborating on an international strategy for planetary science data archiving to: • Give scientific communities world-wide access and services to data archives built from similar standards • Reduce cost of archiving and distributing science data by collaborating and sharing standards • Ensure reusability of science data across agency/mission/instrument boundaries • Coordinate archiving processes and plans • Improve and increase services offered • In 2006, the International Planetary Data Alliance was established which includes participation from major space agencies around the world

  3. ASI (Italian Space Agency) BNSC (British Space Agency) CNES (French Space Agency) DLR (German Space Agency) CNSA (China Space Agency) ESA (European Space Agency) ISRO (Indian Space Agency) JAXA/ISAS (Japan Space Agency) NASA (U.S. Space Agency) RAS/RKA (Russian Space Agency) Members

  4. Organization • Proposed to be under the auspices of COSPAR • Steering Committee to be held at 2008 COSPAR Meeting • Steering Committee with Representatives from all Major Space Agencies • SC oversees IPDA projects • Definition of requirements • Data Model Constructions • etc IPDA Organization Model

  5. Architecture • IPDA Reference System Architecture is decomposed into three core pieces: • Process Architecture • Describes a set of standard processes for planetary science archive data systems • Data Architecture • Describes a set of data standards for planetary science archive data systems • Technology Architecture • Describes a set of standards for enabling interoperability between planetary science archive data systems • Each of the above will provide a set of deliverables to guide system development and operations IPDA Architecture Framework

  6. International Data Standards Standards Structure (IPDA and Agency Level) Data Object Model • Identify the existing subset of standards used by PDS/PSA which are • appropriate for internationalization • PSA based its standards on the PDS Data Standards • Develop a mechanism for management of the standards at an international • level (e.g., coordinated through the IPDA Archive Data Standards Project) • Align existing agency standards and processes with the internationalization

  7. Technology Standards Definition Move towards interoperability and data sharing based on a common data sharing protocol ___________________ Venus Express (ESA) Hayabusa (Japan) Chanrayan-1 (India) Various Missions (NASA)

  8. IPDA Near-Term Deliverables
