Reminded OMF members on difference between issue and pull request with respective procedures for submitting
Comment from Stephen S.: Can use GTFS stop_id in events to link to GTFS stops.txt
Change suggestions:
- Need to add gtfs_api_url documentation somewhere
- Note that gtfs_api_url maybe different depending on the jurisdiction
- Stop_sequence may not be necessary in trips or telemetry (only needs to be in events)
Matt made updates to the request on Feb 19, after feedback from meeting.

Wonderful to see you Rupal! 00:06:20 Michael Schnuerle (OMF): OMF member steering committee https://docs.google.com/forms/d/e/1FAIpQLSftC7Lz2-bJLyX6XzgKWSrmCOBx75K2s8mr5DrZRFVtBPorIQ/viewform 00:07:00 Aylene McCallum // OMF: Open Mobility Mixer in Denver - RSVP here: https://open-mobility-mixer-denver-2025.eventbrite.com 00:07:36 Aylene McCallum // OMF: Please share on Linked In and invite your digital infrastructure colleagues located in Denver to join us! 00:08:23 Andrew Glass Hastings (OMF): Free drinks and friends!! 00:08:48 Aylene McCallum // OMF: Lots of mobility nerds have already RSVP'd for the Denver event so you will definitely make friends 00:08:52 Athan Rebelos Curb Mobility: Athan Rebelos Curb Mobility 🚖 00:09:27 Aylene McCallum // OMF: A very nostalgic Open Mobility Mixer 00:09:38 Andrew Glass Hastings (OMF): Reacted to "Athan Rebelos Curb M..." with 👍 00:10:30 Angela Giacchetti: OMF’s 2025 event calendar can be found here: https://www.openmobilityfoundation.org/2025-calendar/ 00:18:10 Andrew Glass Hastings (OMF): Love that SFMTA goal of standardizing mobility data formats - perfect for MDS! 00:24:23 RUPAL BAPAT (City of Chicago BACP): Reacted to "Love that SFMTA goal..." with 👍 00:27:59 Michael Schnuerle (OMF): Follow along with the Pull Request and leave your comments and replies to comments at the bottom. https://github.com/openmobilityfoundation/mobility-data-specification/pull/927 00:31:42 Stephen Siciliano (Seattle DOT): Curious about an incrementing integer for stop_sequence as opposed to using the GTFS stop_id (which seems like it’d be more stable for long-term analysis; also if multiple routes serve the same stop you’d be able to understand that). 00:31:48 Michael Schnuerle (OMF): Reacted to "Curious about an inc..." with 👍🏼 00:36:05 Matt Davis (Populus): Reacted to "Curious about an inc..." with 👍 00:36:12 Stephen Siciliano (Seattle DOT): Sounds great! 00:36:53 Andrew Glass Hastings (OMF): Safe space - no dumb questions! 00:41:37 Matt Davis (Populus): What is the larger utility of the providers.csv file in MDS? I’ve been using MDS for several years and I don’t think I’ve ever used it. 00:55:01 Matt Davis (Populus): Definitely on Events and Trips. Not sure it needs to be on Telemetry. 00:56:21 Pierre Bouffort (Blue Systems): Reacted to "Definitely on Even..." with 👍 00:56:36 Pierre Bouffort (Blue Systems): Agree with Matt on the above :) 00:57:54 Matt Davis (Populus): Could see it being useful on Telemetry if we care about which telemetries are on trips (while moving between stops) and which telemetries are from being stopped or something?
That relates to how we define a “trip” for this mode. Is a trip defined as moving between stops? Is it defined at all? 00:59:40 Matt Davis (Populus): Telemetry objects do have a journey_id field that could be used to tie together telemetries from the same “journey”. 00:59:51 Michael Schnuerle (OMF): Reacted to "Telemetry objects do..." with 👍🏼 01:00:39 Chay Mosqueda | WFRC: I have to run to another meeting! Have a good day all 01:01:03 Pierre Bouffort (Blue Systems): I think it would, I believe the trip would describe the movement from stop A to stop B, and the overall route would be described by the journey altogether (ie. the group of trips pu together).
To your point about telemetries, I believe we would only use the stop identification with the events, and not the in-between telemetries. Generally, we believe telemetries is mostly to give individual breadcrumbs of GPS between events 01:02:20 Christy Hirsch, Blue Systems: Thank you, Great Meeting! 01:02:20 Armand Shahbazian / Seattle DOT: thanks!
