KDE PIM/KPublicTransport/Endpoint Configuration

Public Transport Provider Endpoint Configurations

Can we share public transport provider API endpoint configurations with a wider set of users, beyond KDE? What would be a sensible subset of information?

Motivation

• All existing projects use subsets of available endpoints, so most if not all could benefit from more endpoint configurations becoming available with little extra effort for them.
• Maintaining endpoint configurations is work, some parameters require elaborate research to obtain.
