It was decided at an early stage that PSA data would comply with PDS Standards:

  • It was decided at an early stage that PSA data would comply with PDS Standards:





Development of our validation tool has highlighted several inconsistencies in the PDS Standards and the way in which various experts interpret them » IPDA

  • Development of our validation tool has highlighted several inconsistencies in the PDS Standards and the way in which various experts interpret them » IPDA

  • PDS and PSA are drawing upon the lessons learned on both sides of this working relationship in order to refine and streamline the Standards.

  • These ‘lessons learned’ are being used by the IPDA to help develop a refined set of IPDA recommendations for archiving that will allow for international archive interoperability and avoid similar issues in future.

  • Some issues also input to PDS2010 (PDS4) development.

  • Involved in PDS2010 System Review and in IPDA assessment of PDS4



VEX - First interoperability studies between PDS and PSA

  • VEX - First interoperability studies between PDS and PSA

    • Access to data remotely
    • Full search functionality
    • Transparent access to data on various servers
    • Planned for PDS data access on VEX


“Difficulty” to control Dataset delivery schedule

  • “Difficulty” to control Dataset delivery schedule

  • Incomplete deliveries to the scientific community as calibrated data deliveries are not available in time by some experimenter teams on the on-going planetary missions

    • Still not fully resolved
  • Insufficient resources within some of the experimenter teams

    • To be solved with new concept in Solar System Science Operations Division - but can only be done partially. Issue was addressed with delegations (SPC) on a number of occasions
  • Parallel activities in member states – we try to coordinate and focus resources



Standard evolution. With IPDA (all international partners), and maintaining our well established links with PDS, we follow PDS-Standard Evolution.

  • Peer Review handling – data are sometimes slow to be released through the formal procedure

  • Data set ingestion turnaround

    • Manual process
  • Potential Remedy actions

    • Planning & monitoring through Dataset Spreadsheet
    • Try automate ingestion process?
    • Review Peer-review concept?
    • Immediately release the incoming Datasets as “provisional”?
