-MDS is intended to be used for multiple transportation modes, including its original micromobility (e-scooters, bikes, etc.) mode, as well as additional modes such as taxis, car share, and delivery bots. A given `provider_id` shall be associated with a single mobility [mode], so that the mode does not have to be specified in each data structure and API call. A provider implementing more than one mode shall [register](/README.md#providers-using-mds) a unique `provider_id` for each mode.
