The Mobile JSON Wire Protocol Workshop` was a two-day workshop held in London, where representatives from various mobile automation projects, including `Selenium Project`, `ios-driver`, and `Selendroid`, came together to discuss the development of standard specifications for mobile automation. The goal of the workshop was to create a standardized protocol that would ensure maximum interoperability between frameworks and promote collaboration among project teams. The event was led by the `Selenium Project` and aimed to build on their success in developing standards for web automation with the W3C. Over two days, participants made significant progress in planning the specs of a standardized mobile automation protocol and developing roadmaps for submitting extensions to W3C and implementing changes in automation servers and client libraries. The workshop's outcome is expected to greatly benefit users of mobile automation frameworks, providing them with greater flexibility and protection from vendor lock-in, while also promoting growth in the open source community.
