This policy brief presents the Interoperability Platform, Finland’s metadata service supporting the creation, publication and reuse of semantic resources in one shared environment. It explains the rationale behind a shared semantic capability to reduce duplicated work, make existing resources easier to find, and promote gradual convergence through reuse rather than attempting to impose a single standard upfront.
The brief explores how the platform is used in practice, highlighting the key design features that allow organisations both to publish and maintain the semantic resources they own and to search, view and reuse what has already been published. It shows how the platform has evolved into a mature capability, used consistently in high‑value national contexts such as the Suomi.fi Service Catalogue, and distils practical insights and lessons learned for administrations seeking to develop similar solutions.
