Open source has been highly democratized thanks to a clear OSI defintion. In a Digital infrastrcuture world, now it is the time for APIs to have such open and clear defintion. Inspired by Open Source, this talk will present the FACT framework, a way to create and publish easily Fair API Commitment Terms, making API Terms of Service that are easy to read and understand. Indeed, the biggest threat on trust in the digital infrastructure we know is the threat on APIs you consume for your software. What if the API provider breaks the API? What if the API provider change its licence? Its version abruptly making it a breaking version without notice? Its pricing making it unaffordable for all users? This is why we have worked to make a framework to make it easy to provide clear open commitment about your APIs to your community. It is like a Creative Commons for APIs, as it is also easy to read and understand for users about what they can expect about API provider commitments about trust for their API. This project has been supported by the Ford Foundation, Mozilla foundation and Open Society foundation.rThis talk will present the FACT framework, a way to create and publish easily Fair API Commitment Terms, making API Terms of Service that are easy to read and understand.
