  1. The International Planetary Data Alliance (IPDA): Activities in 2010-2012Daniel Crichton, Alain Sarkissian, Yasumasa Kasba, Mara Teresa Capria, Reta Beebe, J. Steven Hughes, Pedro OsunaCOSPAR 2012Mysore, India19 July 2012

  2. Moving Towards International Interoperability • In 2005, an initial plan was developed to explore interoperability between ESA Planetary Science Archive and NASA Planetary Data System • ESA and NASA shared same data standards based on PDS v3 • In 2006, the IPDA was formed with an initial Steering Committee with representatives from several agencies • In 2008, COSPAR officially recognized IPDA for setting archiving standards via a resolution in Commission B • IPDA has just completed its 7th meeting COSPAR 2012

  3. Mission of IPDA* • “Facilitate global access to, and exchange of, high quality scientific data products managed across international boundaries” • Support construction of compatible archives • Support sharing of tools and software services • Define “data standards within the IPDA, including the data models and derived dictionaries, based on the NASA Planetary Data System (PDS) that is the de-facto standard for all planetary data at the time of the IPDA founding” * Extracted from IPDA Charter, July 2007 COSPAR 2012

  5. Constructing International Planetary Data ArchivesStandards COSPAR 2012

  6. IPDA Standards Architecture • The 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 • IPDA has initiated projects in each of these areas A Reference Architecture is a set of best practice specifications that can be used for guiding the implementation of a system COSPAR 2012

  7. Focus in 2010-2012 • Development and Coordination with PDS on the next generation PDS (PDS4) to enable construction of compatible planetary archives • Development of a Planetary Data Access Protocol to access planetary archives • Development of international registries to enable registration and search of data, tools and services • Standards related to geometryand navigation • Improvements in the operation and administration IPDA and release of standards COSPAR 2012

  8. PDS4: Next Generation PDS • PDS4 is an upgrade from PDS version 3 to version 4. • Drive consistency across future archive products • A transition from a 20-year-old collection of standards and tools to a modern system constructed using best practices for data system development to enable international planetary data archives. • Fewer, simpler, and more rigorously defined formats for science data products. • Use of XML, a well-supported international standard, for data product labeling, validation, and searching. • A hierarchy of data dictionaries built to the ISO 11179 standard, designed to increase flexibility, enable complex searches, and make it easier to share data internationally.

  9. COSPAR 2012 7th IPDA Steering Committee Meeting, July 11-13, 2012, Bangalore, India

  10. Projects 2011-2012 • PDS4 Prototype Project - S. Martinez, ESA • Registry Development - S. Hardman, NASA • PDAP Development and Coordination - J. Salgado, ESA; Y. Yamamoto, JAXA; N. Hirata, Univ of Aizu; Alain Sarkissian, IPSL/LATMOS; Michel Gangloff, CNES • IPDA Query Language - S. Hughes, NASA • Website Development - E. Law, NASA • Geometry - C. Acton, NASA COSPA 2012

  11. PDS4: Moving towards an International Archive and Infrastructure Standards Structure (IPDA and Agency Level) Data Object Model • Identify the existing subset of standards used by PDS/PSA which are • appropriate for internationalization; Collaboration with PDS improvements to its • data standards in PDS4 • 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 COSPAR 2012

  12. Agency Testing of PDS4* • PDS is making a big effort to refine the information model. Major decisions made on the XML technologies (i.e. reusability, XML Schema 1.1 and the combination of XML Schema and Schematron) are considered a clear improvement to the PDS4 information model implementation. • Versions 7-8 of the XML Schemas address many of the key issues identified by the IPDA PDS4 project last year (e.g. define further restrictions on attributes/classes/types). • Some of the issues identified last year have been postponed by PDS for later releases (e.g. local data dictionaries, documentation) and therefore were not evaluated during these exercises.

  13. Cross Agency Access, Registration and Search of Planetary Archives Search Service supports the PDS and PDAP protocols enabling development of other portals and applications on this infrastructure. • Registered Objects: • Websites • Data Sets • Investigations, Instruments, etc. • Tools and Services Search results include mission support pages and other more specific search interfaces. COSPAR 2012 See Poster B09-0018-12

  14. Example: PDS Search of PSA Data sets and other results returned include products from NASA and PSA. PSA data sets currently link directly to a PSA web-based interface. COSPAR 2012

  15. Remote Query Example • Navigate to the API endpoint: • http://pdsbeta.jpl.nasa.gov/tools/search-service/pds/search?term=“venus express”&return-type=xml • The following should appear in the browser: • <response> • <lst name="responseHeader"> • <int name="status">0</int> • <int name="QTime">1</int> • <lst name="params"> • <str name="term">"venus express"</str> • <str name="return-type">xml</str> • </lst> • </lst> • <result name="response" numFound="114" start="0" maxScore="1.8728198"> • <doc> • <float name="score">1.8728198</float> • <str name="title">VENUS EXPRESS SKY/VENUS SPICAV 2 SOIR EXT2 V3.0</str> • … The “term” parameter is the equivalent of text-based search. Parameters that were passed in the search criteria. Number of results returned and the position in the result set. COSPAR 2012

  16. IPDA Endorsements at 2012 Meeting • Reviewed SPICE endorsement • July 2010 recommendation for agency adoption of SPICE (no change) • Recommendation to continue a geometry project to improve geometry specification (in future releases of PDS4) • Established endorsement of PDS4 data standards • Testing over the past year by many agencies supports movement forward • Move from cross-agency testing to early adoption for future missions (e.g, BepiColumbo) • Supply results of testing back to PDS4 design teams

Stein, Wash Univ • PDAP Core - J. Salgado, ESA • PDAP/PDS4 Integration - S. Hughes, NASA • Geometry - C. Acton, NASA COSPAR 2012

  18. Summary • Excellent progress observed at the 7th IPDA Meeting • Excellent collaboration between IPDA and PDS regardng PDS4 • Testing of PDS4 Standards • Interoperability between ESA and NASA with PDAP • Establishment of an IPDA registry • Cross Agency Search • The projects in 2013 continue to move IPDA towards a achieving the goal of building compatible planetary science archives and providing interoperability COSPAR 2012
