No discussion, approved - IEEE SA Patent & Copyright Policies; Participant Behavior
Patent and copyright slides were shown and discussed by the chair. Chair provided an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard.
No discussion. - SAR ARD/CEOS/ISO
SiriJodha discussed CEOS efforts to define analysis-ready-data (ARD), how ARD may relate to SAR, and what the crossover from ARD to standards processes like ISO/OGC might be.
There was some discussion about what ARD means for SAR and how it may mean different things from different viewpoints. It was commented that Geocoded SLC is often referenced as SAR ARD, but may not be ideal for all SAR processing scenarios. - Status recap and path forward discussion
Recap was given on previous progress. NGA/IEEE copyright agreement, previous draft, and previous technical analysis. Contributed funding now provides dedicated resources for completing the writing.
Question was raised about whether document should be pure UML or whether it should target more concrete representation such as JSON/XML. If it is pure UML, a previous example was looked for. (Some ISO links were provided, such as https://standards.iso.org/iso/19115/resources/namespaceSummary.html). General consensus seemed to be that the group should migrate toward targeting a concrete representation, as purely abstract standards sometimes struggle to gain traction. (After the meeting, it was later determined that such a change would require a PAR modification, so discussion will have to continue in next meeting, and that will need to be a more formal decision by the group with two-thirds approval.)
There was some discussion if P4002 should be leveraging other ISO UML modules into the P4002 standard. Guidance was provided that we should be bringing the P4002 draft in line with other internal standards such as ISO, as reasonably practical.
Aligning with STAC was also discussed, both for directing P4002 work to align with existing STAC, as well as opportunity to influence STAC’s future direction, as it is not mature for SAR yet (https://github.com/stac-extensions/sar). - Unfinished Business/Action Item Review
