(Note: Mike Beckerle cannot attend today's call.) Notes from the missing: Summary of OGF22 presentation - There is not much to say here. There were about 15 attendees. A few questions, and people were pleased to see progress. No volunteers to implement/review/help out. Next OGF23 is Barcelona, after that OGF24 is Singapore. Those are both this year. Value Calc - example was circulated as powerpoint. Suggest review of this for next call on March 5. Agenda topics scheduled for today include: - Discussion of Simon's UML diagrams for the schema components
