The Mobility Data Specification (MDS), a project of the Open Mobility Foundation (OMF), is a data standard to enable right-of-way regulation and two-way communication between mobility companies and local governments.

MDS is a key piece of digital infrastructure that supports the effective implementation of mobility policies in cities around the world. For a high level overview and visuals, see the About MDS page on the OMF website.

The OpenAPI description for MDS data feeds is managed by the Open Mobility Foundation. This schema can be used to validate your MDS public or authenticated API endpoint data feeds automatically and on demand.

Interactive online documentation is available on Stoplight.

Starting with MDS 2.0, OpenAPI documents describe MDS endpoints and allow for schema validation, expanding on the prior JSON Schemas work. MDS versions are organized by branches starting with a branch for v2.0.

The Mobility Data Specification (MDS), a project of the Open Mobility Foundation (OMF), is a set of Application Programming Interfaces (APIs) that helps cities better manage transportation in the public right of way, standardizing communication and data-sharing between cities and mobility providers, allowing cities to share and validate policy digitally, and enabling vehicle management and better outcomes for residents. Inspired in part by projects like GTFS and GBFS, MDS is focused on managing mobility services such as dockless scooters, bicycles, mopeds, car share, delivery robots, and passenger services.
