This presentation introduces a generic approach to supporting the repository community's implementation of new metadata standards and guidelines. We will first discuss the challenges in adopting metadata standard and guidelines across repositories in an interoperable manner, sharing our decade-long experience with harvesting and processing metadata from repositories. We will then describe the components needed to ensure a community-driven approach which we argue will lead to a better adoption across the sector, benefitting all stakeholders. leading to a proper adoption. . We will illustrate this approach on a project the CORE (core.ac.uk) team is currently carrying out to support the uptake of v3 by the Eprints community.
