Agenda
- Welcome
- Secretariat updates (Anna)
- WMDR2 Roadmap: https://github.com/wmo-im/wmdr2/wiki/WMDRRoadmap
Notes
- The team discussed the WMDR Codes and I-Adopt mapping spreadsheet (read-only link)
- It would be good to make sure we can track the changes in the spreadsheet (more effective than comments)
- It was noted that this could have a really big impact if this impacts the URIs. Most of the "notations" will not change but the combination of multiple tables will change the URIs. E.g. //codes.wmo.int/wmdr/ObservedVariableAtmosphere/12057 could become //codes.wmo.int/wmdr2/ObservedVariable/12057.
- (John) question on the WMDR code 'bathymetry', but if we change it to be more "correct" (e.g. 'Depth of the ocean') then we lose the legacy name of the subject.
- (Joerg) we have a mix of species and properties and it's not uniformly applied in WMDR
- (Gao) NASA is launching a similar effort in esdwg; it would be useful to be backwards compatible with notations;
- (Anna) how does this differ/relate to ontologies? (Joerg) I-Adopt is an ontology but more manageable
- (John) ..(?)...
- (Anna) Would you have the same notation for "Bathymetry (13)" for oceans and lakes? (Joerg) that's not the idea, there would be two different notations, the specificity is important; note that the context is not currently required by I-Adopt (Gao) I-Adopt is a concept that is being interpreted
- (Anna) Q about implementation in the codes registry (Joerg) It would be great if the codes registry can generate the name from the elements/items associated with it. The WMDR2 UML model shows the "observedVariable" with other "classes" for the I-Adopt items. In the end, one phrase associated with the observed thing is needed;
- (John) Will the constraint in "18, Atmospheric Density" become part of the name? (Joerg) it could be very useful for users in a UI to have it upfront and clear;
Actions
- Anna add undiscussed issues from 17 August to next meeting's agenda
- Gao will look at the atmospheric variables in the spreadsheet
- John will look at variables that he's familiar with
Next meetings
