CERN viewpoint

<!--HTML-->REVA is an implementation of CS3 APIs which has become a key component of several systems: 1) CERNBox service (where it was originally developed) 2) Interoperability Platform (IOP) for ScienceMesh with 3rd party connectors to Owncloud, Seafile and Nextcloud 3) Core module and dependency of ownCloud Infinite Scale A roadmap and agreement on governance is needed to define the direction in which REVA will continue to evolve and to ensure that needs and perspectives of all REVA users are harmoniously reconciled: 1) open platform welcoming contributions from the FOSS community at large; 2) vendor-neutral interoperability component for European Open Science Cloud; 3) efficient implementation layer for commercial products supported by interested vendors; 4) efficient implementation layer for specific service deployments in the CS3 community.
