1. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) International Planetary Data Alliance (IPDA) Introduction and Overview Prepared by IPDA Steering Committee Members December 2006

2. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) Background Scientific community in the U.S. decided in the eighties to setup a data system for planetary related data (ground-based, laboratory data, space data) –Planetary Data System (PDS) –Maintain data standard (PDS-Standard) –Maintain and distribute data –Distributed setup via discipline nodes –NASA adopted PDS as the data system for planetary missions Scientific community in Europe got acquainted to the PDS-Standard, as most data originated from NASA missions –ESA’s first planetary mission (GIOTTO) was archived using the PDS-Standard, actually it was archived by the PDS-Small Bodies Node –ESA adopted the PDS-Standard as the base standard for it’s archival system, the Planetary Science Archive (PSA) Now containing data from Giotto, Mars Express, Huygens, ground-based observations and soon Rosetta, Smart1 and Venus Express. Exploration missions likely to use same standard, e.g. ExoMars will archive using the PSA PDS and PSA see need to close co-operation –To give scientific communities world-wide similar data archive access and services –To avoid diverging on archiving issues –To improve and increase services offered –To reduce costs by sharing efforts –…

3. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) Incentive Other space agencies need to setup similar archival systems, including standards, tools, services, etc in the coming years to serve ‘their’ scientific community –Co-operations make it necessary to minimize the differences between systems and standards, e.g. Rosetta (NASA,ESA), BepiColombo (ESA,JAXA), Chandrayaan (ISRO,ESA), … –Wish from archival systems to share lessons-learned –Avoid re-inventing the wheel - if not explicitly wanted World-wide scientific communities want to have standardized archival systems –They (often) do not care about Space Agency’s considerations –Demand for new, sophisticated services and tools Concerns in accepting data standards fully controlled by sister agency

4. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) Initiative Internationalize the planetary data archival efforts Within an international effort, consider –Partners –Scope –Schedule, roadmap –(Estimated) costs, savings –Goal

5. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) Internationalization Standards for Data Access and Distribution In 2005, the PSA and PDS initiated an effort to develop common interoperability standards for accessing and distributing data internationally from national planetary science archives this includes –A protocol for finding, accessing and retrieving science products from across agency systems –Common semantics for discipline-specific queries The plan is that joint missions in the future will use the interoperability protocol rather than submitting and archiving data from another agency in a local system

6. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) International Planetary Data Alliance Mission Statement The International Planetary Data Alliance (IPDA) is a close association of partners with the aim of maintaining and continuously improving the quality and services to planetary science data from ground or space based instrument The specific mission of the IPDA will be to facilitate global access and exchange of high quality scientific data products managed across international boundaries and organized by a set of governing data standards

7. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) International Planetary Data Alliance Objectives The main objective of IPDA is the enhancement of the research activities in the worldwide planetary community. The IPDA as a whole shall propose and adopt standards for planetary science data archiving, exchange and access, and will implement accompanying tools in the areas, such as, however not restricted to:  long-term data preservation  data modeling  data dictionary management  interoperability  data generation, validation, access, exchange, visualization and mining  services registry  and others

8. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) International Planetary Data Alliance Basic Idea on IPDA Setup COSPAR –Pursuing a COSPAR resolution at the 2008 Meeting in Montreal –Biannual Meeting at COSPAR conference Steering Committee –defined by Charter –Yearly meeting –Define requirements for IPDA Projects –Nominate IPDA Project Leader Several IPDA Projects –defined by Project Requirements and by nomination of Project Leader –Relatively short-term projects –Current Projects within IPDA IPDA Charter: PL: Y. Kasaba, JAXA IPDA Operational Procedure: PL: S. Hughes, PDS/JPL Interoperability Prototype, PL: J. Salgado, ESA/ESAC COSPAR Resolution, PL: R. Beebe, New Mexico University Core IPDA Requirements, PL: S. Hughes, PDS/JPL IPDA WWW Presence, Initial Setup, PL: D. Crichton, PDS/JPL Communication Channels –IPDA will be based on electronic information exchange –No IPDA teleconferences foreseen –IPDA Project to follow a project template –Regular reporting to Steering Committee and IPDA email distribution list Steering Committee meeting –8-10 November 2006, ESTEC, The Netherlands –17-18 July 2008, Caltech, Pasadena, California WWW presence –url selected: http://planetarydata.orghttp://planetarydata.org –WIKI setup done and basic parts populated

9. I N T E R N A T I O N A L P L A N E T A R Y D A T A A L L I A N C E ( I P D A) International Planetary Data Alliance Membership The IPDA will be represented by a steering committee and working groups. Membership in the groups shall be comprised of representatives from any space agency, scientific research institute, university or other organization that is involved in the production or curation of scientific data relevant to the world-wide planetary science community. Membership in the steering committee shall be comprised of representatives from any space agency, scientific research institute, university or other organization that indicate a willingness to fully participate in the IPDA activities and provide the commensurate level of support for defining and implementing the IPDA standards. Interested partners shall contact the standing committee members and notify them of their approval and acceptance of this Charter, providing a best level of effort to ensure the support and usage of the IPDA proposed standards and tools.
