  1. DDWG / Standards MC Face-to-Face Flagstaff, AZ June 7-8, 2016

  2. Topics • Information Model Status • DDWG • DDWG Task Statuses • Summary

  3. Information Model Status • The PDS4 Common Model remains stable. • V1.6.0.0 of the Information Model is operational under Build 6b. • V1.7.0.0 of the Information Model has been staged for the implementation of CCB approved SCRs. • The international community is engaged.

  4. IM Update Status • 3 - SCRs implemented in the staged V1.7.0.0. • 3 – SCRs approved and queued for implementation • 4 – SCRs queued for resolution • A detailed list of the SCRs is available in the backup slides.

  5. IM V1.7.0.0 Release Schedule • Aug 26, 2016 – All SCRs to be implemented have been identified • Aug 26 - Sep 8, 2016 – Finalize implementation • Release IM to development directory • Internal testing • Address bugs • Sep 9 - Sep 22, 2016 – Node testing • Release IM to development directory • Perform regression testing at EN • Sep 23 - Sep 29, 2016 – Prepare IM for release to System I&T • Sep 30, 2016 – Release IM to release directory • “Start of Build” and System I&T • IM is frozen • System I&T - System Testing • System Release Build

  6. International Community • PDS4 Implementation Plan • PDS4 Standards / Information Model • Working prioritized issues • Propose that selected Mission LDDs be configured for use across missions. Reuse the same attribute names (e.g., mission_phase_name, even though values are mission specific) • Formation rules for context products • PDS4 SW tools • Separate presentation

  7. DDWG • The DDWG continues as the deliberative body for gaining a consensus and making recommendations for changes to PDS4 standards. • The DDWG normally meets for one hour teleconferences every two weeks • The DDWG has met weekly over the last couple of months to resolve a backlog of SCRs. • In general the DDWG Agenda consists of: • SCR Statuses • Tiger Team Statuses • Votes to recommend SCRs to the CCB • Some discussion on open issues.

  8. Documentation Governance 1Propose DPH and Concepts are developed/maintained by a document working group of up to 4 people 2MC may want to consider delegating document reviews…

  9. Task - Geometry Team lead and members: E. Guinness, M. Gordon, A. Raugh, C. Isbell, S. McLaughlin, B. Semenov , C. Acton, E. Rye, S. Hughes Short Description: Capture geometry requirements from across the disciplines, obtain a consensus model, and write a geometry dictionary. Currently focusing on classes for flyby/orbital and landed missions. Goals: Cross-discipline Geometry Model and Dictionary Status: Several rounds of review by DDWG and non-PDS interested parties. Focus has been on classes for lander/rover geometry to support InSight cameras. Orbiter classes mostly stable, but with some comments from DDWG to be resolved. Projected Beta release this month. Next will work on Earth-ground-based observations section.

  10. Task - Cartography Team leads: C. Isbell, J. Padams, R. Joyner Short Description/Goals: Capture planetary cartography requirements and definitions across disciplines and projects. Produce cross-discipline Cartography dictionary compliant with the PDS4 IM. Schedule (Major milestones): Done- Initiated Federal Geographic Data Committee (FGDC) based model, completed initial testing & sample product labels, extended FGDC model for Planetary, presented status to IPDA, completed initial internal review. Done- Additional LDD updates: added latitude_type, request spheroid_name & reference_framemove (to GEOM), add/update scale/resolution attributes & descriptions. Done - Completed internal PDS review. Implemented updates. Done (Oct 2015) – First operational version released, v1.5.0.0 (expect additional adjustments per wider use). Current – PDS_CART_1500.xsd, .sch, .xml available at PDS4 schema web-site. Modifications/updates are now made as needed per new mapping products, new missions, new requirements.

  11. Task – PDS4/NSSDCA Interface Team lead and members:McLaughlin, Bell, McCaslin, Kodis, Hughes, Hardman, Joyner, Guinness, Huber, Isbell, King, Raugh Short Description & Goals: Develop an interface for transferring PDS4 data to the NSSDCA deep archive: • Automate deliveries; eliminate multiple ingests of products • Provide the ability to return basic products, collections and bundles from the deep archive; report on those entities • Perform data integrity checks Schedule (Major milestones) Mar:May – Continued testing functionality of sample SIPS; Began exercising prototype product ingest database using sample SIPs. Jun:Aug – Software will be provided to generate SIPs; Host all-hands telecon to bring everyone up to date; Exercise prototype product ingest database using real-world SIPs (for completed, officially archived bundles). Sep:Nov – Fine tune procedures; Release product ingest database into production environment.

  12. Task - Document Improvement - 1 Team members: R. Joyner Short Description: Address issues associated with the PDS4 Data Standards documents; update documents as needed. Goals: Consistent data standard documents and information model. Schedule (ongoing work): • Support Documents – Planned Reviews and Updates • PDS4 Concepts document (revised, posted for v1.4) • Glossary (included in above) • DD Tutorial (included in above)

  13. Task- Document Improvement - 2 • Standards Reference (revised, posted for v1.4) • Comments from IPDA; received but not evaluated • Data Providers’ Handbook • Sent to CCB for review; comments sent back • DPH updated with CCB comments • Need to determine best path to review and release • Need to determine future of DPH with respect to different types of data providers

  14. Summary • Build 6b is in operation under V1.6.0.0 of the Information Model. • V1.7.0.0 has been staged. • CCB approved SCRs are being implemented. • SCR Queue • Several “older” SCRs have been resolved. • The queue of new SCRs are resolved for each build.

  15. Backup

  16. Implemented SCRs •   CCB-150 - Modify <Product_Context> to accommodate Balloon •   CCB-157 - Remove sampling_parameters attribute from Uniformly_Sampled •   CCB-158 - Restore J2C as valid format for supplemental data

  17. SCRs Queued for Implementation •   CCB-152 - field_format definition mismatch between IM and SR •   CCB-159 - Bug fixes for Version 1.7.0.0 •   CCB-160 - URN prefix for the Japan Aerospace eXploration Agency (JAXA)

  18. SCRs Queued for Resolution •   CCB-149 - Should PDS4 allow packed data? •   CCB-151 - Bundle_Member_Entry and Internal_Reference do not require either LID or LIDVID. •   CCB-154 - Promote Mission_Information class to Discipline Governance Level •   CCB-156 - Inconsistent Discipline Dictionary Technique for Local_Internal_Reference, et al.
