SBN PDS4 Migration Planning

PDS MC at UCLA, 29 November 2012

considerations
Considerations
  • Significantly improved search under PDS4 for SBN products generally, and ground-based data in particular.
  • Significant support for documentation and auxiliary data products under PDS4.
  • Inclusion of SBN discipline classes could provide even more search benefits, plus automation benefits for SBN website.
  • Central catalog currently lists 914 SBN datasets.
  • A significant fraction of these are superseded or safed data.
selection criteria
Selection Criteria
  • Final/latest versions only – superseded and safed data will not be migrated.
  • High-interest data sets – current DAP candidates; NASA challenge data; etc.
  • High-value data sets – property catalogs and collections referenced by many end-users.
  • Low-hanging fruit
psi plans
PSI Plans
  • First draft of conversion tool to handle OLAF-produced data sets done.
  • LADEE/LDEX data from this tool will be reviewed in December
  • OLAF-produced data sets can then be migrated largely mechanically and should take 1-2 months.

Caveats:

  • Cannot include improved search parameters
  • Cannot include non-observational data files.
umd plans
UMD Plans
  • Shamelessly pirate other tools for useful code; add code to handle search parameters and node classes.
  • Plan for hand-crafting non-observational products (documentation, etc.) as part of the migration for each data set.
  • High-priority data used for migration testing will be the first to be re-migrated to 3b. Beyond that, priorities will be periodically re-assessed.
  • All migration will have to be on an “as resources are available” basis.

Consequently, it will likely take 2-3 years to migrate most of our data sets, and some problematic collections (Rosetta, e.g.) may take substantially longer.

software migration
Software Migration
  • Online Archiving Facility (OLAF): Schedule TBD. The current plan is to use OLAF in conjunction with the PSI migration tool at least until the first public PDS4 release.
  • IDL tool: readpds.pro – A draft version (browse_pds.pro) is in testing now, awaiting more data products.

Related Topics
  • Data Ferret migration
  • Web site upgrades to take advantage of new PDS4 search & packaging capabilities
  • Acute Russian interest in PDS4 archiving and related IPDA activities, and especially in multi-lingual potential for data dictionary support.
  • Development of new maintenance procedures for node archives.
  • Development of new procedures for deep archive delivery/retrieval
