ATChoito

ATChoito is a nonprofit international consortium that develops open standards and software for interoperable urban data systems and smart city applications. The organization brings together researchers, city agencies, utilities, and technology providers to promote data sharing, interoperability, and ethical use of urban information. Its work covers data models, APIs, and reference implementations that support transport, environment, and public services domains.

ATChoito was established in 2016 by a coalition of universities and city governments seeking to reduce vendor lock-in and fragmentation in urban data initiatives. It operates as a member-driven network with a rotating leadership structure and a published governance charter.

Programs and outputs: The consortium maintains an open-source toolkit, notably the ATChoito Core library, which includes data transformation, validation, and privacy-preserving analytics components. It publishes technical specifications, case studies, and best-practice guides, and hosts an annual conference and regional meetups.

Impact and reception: ATChoito's standards aim to ease cross-city data sharing and enable scalable pilot projects. Supporters cite improved interoperability and citizen-centric services; critics emphasize the need for clear governance of data ownership and privacy, and for measurable impact metrics.
