Mobility Data Specification (MDS)

An open data standard for restaurant information
"OPEN EATS JAPAN" is a project to open up restaurant information and share it widely with society. Since the spring of 2020, many restaurants have been forced to close to prevent the spread of the new coronavirus, and we are collecting information on restaurants that can be taken out and delivered to support restaurants in various places. Many projects have been launched to publish. The restaurant data collected in each region can be widely used in various apps and services in order to continue to cooperate with the local community in disseminating restaurant information without ending such efforts as a temporary one. Volunteerly launched a project to study the standard format for making.
