  FAIR principles have the intent to act as a guideline for those wishing to
enhance the reusability of their data holdings and put specific emphasis on
enhancing the ability of machines to automatically find and use the data, in
addition to supporting its reuse by individuals. Interoperability, one core of
these principles, especially when dealing with automated systems' ability to
interface with each other, requires open standards to avoid restrictions that
negatively impact the user's experience. Open-ness of standards is best
supported when the governance itself is open and includes a wide range of
community participation. In this contribution we report our experience with the
FAIR principles, interoperable systems and open governance in astrophysics. We
report on activities that have matured within the ESCAPE project with a focus
on interfacing the EOSC architecture and Interoperability Framework.
