The Mobility Data Specification (MDS), a project of the Open Mobility Foundation (OMF), is a set of Application Programming Interfaces (APIs) focused on dockless e-scooters, bicycles, mopeds and carshare. Inspired by projects like GTFS and GBFS, the goals of MDS are to provide a standardized way for municipalities or other regulatory agencies to ingest, compare and analyze data from mobility service providers, and to give municipalities the ability to express regulation in machine-readable formats. MDS helps cities interact with companies who operate dockless scooters, bicycles, mopeds and carshare in the public right-of-way. MDS is a key piece of digital infrastructure that supports the effective implementation of mobility policies in cities around the world.
