PDS 4 Status - Testing 28 -29 August 2012 Radio Science Report to PDS MC 3

PDS 4 Status - Testing • Migrated a single DSN binary data product (RSR) to PDS 4 0900 B o. Data file unchanged o. XML label created (based on PPI template from Ron Joyner and PDS 3 label) • Migrated three documents to PDS 4 o. One TXT file unchanged o. Three ASC files unchanged o. One HTM file unchanged o. Three XML labels (based on RSR label above) • Created one XML schema product o. One XSD file from Steve Hughes o. One SCH file from Steve Hughes o. One XML label based on template from Ron Joyner • Created 7 Context products o. One mission, two host, one instrument, three target XML files 28 -29 August 2012 Radio Science Report to PDS MC 4

PDS 4 Status - Testing • Created Product_Collection for each Collection o. Created ASCII inventory table from IM 0900 B o. Created XML label • Created Bundle Product for the Bundle o. Created XML Product_Bundle • o. Xygen validation successful • Dialog in progress with EN regarding other issues 28 -29 August 2012 Radio Science Report to PDS MC 5

PDS 4 Status – Mission Support Nothing planned 28 -29 August 2012 Radio Science Report to PDS MC 6

PDS 4 Status – Migration Proposal 1. Gain experience with PDS 4 by migrating a few high-level, investigator-produced, ASCII data sets (e. g. , radio occultation profiles, spherical harmonic gravity models). May reorganize some PDS 3 data sets into more convenient pieces. 2. Develop a set of templates and labeling tools which can be applied to DSN output files (mostly binary) — both old and new 3. Use the opportunity to port/upgrade software to the new Stanford computer and work on the restoration queue as resources allow 28 -29 August 2012 Radio Science Report to PDS MC 7

PDS 4 Status – Tools • • • Mac OSX readers for DSN output files Templates for XML labels Search-and-Replace Mac OSX scripts to create XML labels • • • Scripts to create Collection inventory tables and labels Scripts to create Product_Bundle products Test, analysis, and display software as needed • Time frame: unknown, but probably years 28 -29 August 2012 Radio Science Report to PDS MC 8

PDS 4 Status – Issues • There a lot of details • Forward motion depends on stability of the Information Model, schemas, and the supporting system • Documentation (and its medium) remains a patchwork • How PDS 4 evolves will depend on tools, how users react to them, and what needs to be upgraded to support the unanticipated requirements 28 -29 August 2012 Radio Science Report to PDS MC 9
