Roadmap

👋 MobilityData created this space for you to share your big picture plans and to see ours.

This is meant to be a list of major features. More granular items (e.g. specific validation rules) are covered in contributing.md.

Backbone infrastructure

🔒 MobilityData believes these items need tighter ownership to ensure stability. Please get in touch with @isabelle-dr to coordinate contribution.

Disambiguate spec, review rules

• Need: There is vague language in the GTFS specification leading to unclear validity in some cases.
• Feature: Clean up the spec, review existing validation rules accuracy according to updated spec.

📅.	👥	🛠️
2021 Q1	Google, MobilityData	Ambiguity in the language of GTFS flagged.
2021 Q2 & Q3	MobilityData	Working on reviewing the rules, adding rules that are missing, and clarifications in GTFS spec.

Evaluate changes on all GTFS datasets

• Need: Changes to Validator should not result in previously valid datasets becoming invalid.
• Feature: Run tests on a large number of expectedly valid datasets. MobilityData plan = leverage the Mobility Archives.

📅.	👥	🛠️
2021 Q1	Google	Suggested feature.
2021 Q2 & Q3	MobilityData	Implementation work.

Custom Validator feature

• Need: Consumers & regulatory bodies have requirements beyond the GTFS spec itself. Producers want test validity against these, too.
• Feature: Allow rules that are not in the spec itself yet but are required by various consumers or regulatory bodies. Validator users should be able to toggle to use their choice of additional rules beyond the core in-GTFS-spec rules.

📅.	👥	🛠️
2020 Q4	Cal-ITP	Suggested feature.
2021 Q3	MobilityData	Design & implementation.

Community features

🤝 Features expected to allow larger autonomy by the open-source community. It's recommended to check in with others here if you're planning major work.

Integration into mobility repositories

• Need: Validity of data should be determined as early as possible to make errors easier to fix.
• Feature: Validator should run whenever data is published/ingested into data portals.

📅.	👥	🛠️
2020 Q3	Cal-ITP, MobilityData	Feature originated in vision discussion.
2021 Q2	MobilityData	Populating the Mobility Archives
2021 Q3	MobilityData	Run Validator on every dataset

Results UI

• Need: A way for users to better understand content of the validation report.
• Feature: A web user interface that will present the content of the validation report.

📅.	👥	🛠️
2020 Q3	Cal-ITP, MobilityData	Feature originated in vision discussion.

Local web UI

• Need: Make the Validator easily usable by anyone.
• Feature: Web user interface that will allow users to use an online instance of the gtfs-validator without having to use the command line.

📅.	👥	🛠️
2020 Q3	Cal-ITP	Feature originated in vision discussion.

Update to reflect GTFS extensions

• Need: GTFS has been extended, validation of the additional concepts would help ease implementation.
• Feature: Add rules for each extensions. Areas needing rules include Pathways, Fares v2.

📅.	👥	🛠️

GTFS Best Practices

• Need: Show if the data is compliant with the Best Practices.
• Feature: Add warnings to show if dataset is not complaint with Best Practices

📅.	👥	🛠️

Validation against previous datasets

• Need: Discover errors that may have occurred as a result of updating dataset.
• Feature: Compare dataset to previous version. Flag if changes are widespread.
