Throughout 2019 Ideal Interface worked with a large number of different organisations and individuals in the transport and mobility sector to develop two API specifications for transport account interoperability (a customer-account API for the consistent integration of purchase, usage and concession data, plus an operator-information API to be the design for a centralised look-up service for all transport providers & MaaS platforms).
The resulted in the release of a draft (v0.9) for peer review in October 2019. Then the subsequent ratification of this standard by industry stakeholders and specialist, leading to its release as version 1.0 on 3rd January 2020.
The full specifications are available here:

From this date these specifications have become Open Standards and therefore they are free to adopt and adapt. Meaning any intellectual property Ideal Interface (or any other contributing organisation) has built up during the design process is now surrendered and we no longer manage any further changes. Instead all oversight and further iterations of the Open Transport standards are managed by a Standards Board run by Open Transport Technology Ltd.

We wish this initiative the best of luck and hope it gets swift and uniform adoption across the transport industry as planned.
