The KM3NeT neutrino detectors are currently under construction at two locations in the Mediterranean Sea and starting to produce valuable data both for the astrophysics and neutrino physics communities. Having committed itself to an Open Science policy, the KM3NeT collaboration is establishing a system to facilitate data sharing, open software development and integration of KM3NeT analyses in common analysis platforms, as well as providing training material. In this contribution, the current prototype architecture and future development initiatives are presented, and the benefit of Open Science for education and outreach highlighted.
