  1. Small Bodies Node Report Michael F. A’Hearn, Donald R. Davis, Ludmilla Kolokolova, & Carol Neese PDS Management Council

  2. Mission Status • Dawn (PDS3) • Panic subsiding, hope to meet PMDAP deadline (12 Sep) • EPOXI (PDS3) • Awaiting re-calibrated data, higher level products, recal DI-data • finish by December • LADEE LDEX (PDS4) • Pre-launch OLAF --> PDS3 --> PDS4, translation tool in progress • Post-launch, OLAF  PDS4 • NExT (PDS3) • Awaiting final products (shape model, recalibrated prime mission) • Finish by December • OSIRIS ReX (PDS4) • Preparing DMAP • Rosetta (PDS3) • Plodding along with lots of work • Release policies diverging PDS Management Council

  3. PDS4 Outline • Tasks required (near-term only) • For data users • For data providers • Readpds.pro details • Internal • Migration test details • Issues PDS Management Council

  4. Tasks for SBN users • Web pages • Announcement, links to PDS4 intro & details @ EN • Overview of migration plan • How to read an XML label • OLAF • Currently working on translation program specifically for current PDS3 output from OLAF • Eventually will produce PDS4 directly • PDS4 -> FITS • Large fraction (30%?) of community uses FITS + IRAF/STSDAS • EN should produce output translator • Readpds.pro for PDS4 • Other large fraction (50%?) of community uses IDL • Routine works on samples created at SBN • Waiting for more samples PDS Management Council

  5. Readpds.pro Details • Replaces the long-standing readpds.pro publicly distributed by SBN • Widely used • Augmented by various users • PDS4 Status • Works on sample products generated months ago at SBN • Not tested on samples generated by other nodes • Many more instances (compared to PDS3) where flags will be used to choose input options • Waiting on some PDS4 definition issues, like node & mission dictionaries, geometry classes • Need lots of examples from all nodes once labels are firm PDS Management Council

  6. Tasks for SBN Data Providers • LADEE-LDEX • Pre-launch review Data will be loaded into OLAF to produce PDS3 products; SBN staff (@PSI) will translate to PDS4 • OLAF to be converted to PDS4 for post-launch data • IKI • Continuing work at low level (separate funding) to teach them PDS4 for their archive • OSIRIS ReX • In contact with team for DMAP preparation • Briefed on PDS4 but not yet ready to prepare products • General • Provide real samples of data in PDS4 • Create node data dictionary • Web pages for intro + links to EN PDS Management Council

  7. Internal Tasks • Lay out revised disk/directory structure • Develop Node Data Dictionary • How do we do this? • Migrate subset of data chosen • To provide examples for readpds.pro • To test registry service • To test validators • To test node and mission data dictionaries • To test “odd-ball” datasets (pure document sets, very large sets, bundles/collections split between PSI and UM, movies, etc.) • Will never migrate superseded or safed datasets PDS Management Council

  8. Migration Details UM PSI PDS Management Council

  9. Showstoppers for Public Release • Node/Mission Data Dictionaries • Geometry classes • Registry service fully tested • Linking raw and calibrated data • Etc. PDS Management Council
