travel-rules's Introduction

Travel Rules Database

Travel rules around the world as an executable Datalog database.

This project makes no claim to the accuracy of the data. The query results cannot be taken as legal advice.

The travel rules for each nation state (in the 3 letter ISO 3166-1 alpha-3 format) is specified in its own Datalog file in the ./state_rules folder. Preferably each rule should have a referenced source that could be checked regularly for updates.

An example session:

Fill in your personal travel information, including passports, visas and/or residence permits you hold (see the sample files in the ./facts folder)
make
See output/can_visit_state_formatted.csv. An excerpt is included here:

travel-rules's Issues

Each rule should have an ID for verification

For debugging or paper-trailing, we should have a way to list out why a decision was made.

Safer and more discoverable enums

Many of the enum values we're using are just plain symbol. For example Visa/passport types, country code, etc. We should make them proper enum to avoid data entry errors and to facilitate building friendly UI in the future.

Implement passport requirements

Some countries require the passport expiration date to be at least N months after expected leaving date. Some require the passport to not be more than 10 years old.

Get the country code from iso.org

Current data is from Wikipedia.

CI job to test that the main script at least compiles correctly

Scheduled job to check if referenced Internet sources have changed

Many rules refer to Internet sources. They may change over time. We should have a scheduled job once per week or so to check if anything needs to be updated.

This requires that the sources be included in a machine-readable way.
