Notes

Board approved the merger of the City and Provider Working Groups into a single MDS Working Group.
- Consolidating mailing lists, wiki pages
- Making a new charter
Neil presenting about "Tiered Dwell Time with Rates" pull request adding policy examples of parking fees that vary over the duration of the parking event
- https://github.com/openmobilityfoundation/mobility-data-specification/pull/658
- In response to this question posted as an issue: https://github.com/openmobilityfoundation/mobility-data-specification/issues/631
- Matt Davis asked a clarifying question about rate amount: rate amount is always per time unit, so to represent a $2 fee per 30 minutes you'd divide 200 cents / 30 minutes = ~7 cents per minute
- Emmett asked about whether rates apply as soon as they match a time unit (e.g. at the start of an hour), or after the completion of the time unit. Policy lets you specify either option via different rate_recurrence options.
- Sebastien Berthaud asked whether the examples in the PR are based on real use cases. Answer is yes, Jean's original post in #631 was motivated by real world use cases. One example is this from Omaha, NE (page 27): https://cityclerk.cityofomaha.org/images/agenda/ID_20_07_14/RES-2020-0583.pdf
- Neil continues to discussion of Matt's suggestions in #666 and #677
- #666 suggests adding a flag of whether a rate applies when an event matches a rule or when it does not
  - Implementing #666 doesn't block #658, but we do need to clarify whether rates apply to rules when events match or when they do not
- Matt raises the question of how one knows whether a rule applies to individual units or an entire group of things (whether that's vehicles or units of time)
  - This will probably require additional clarification
- Regarding whether rule minimum and maximum are inclusive (#677), Neil suggests that that may need to be configurable to support all rule types
