The Ocean Data and Information System (ODIS) is a federation of independent data systems coordinated by the International Oceanographic Data and Information Exchange (IODE) of IOC-UNESCO. This federation includes continental-scale data systems as well as those of small organisations. ODIS partners use web architectural approaches to share metadata describing their holdings, services, and other capacities. This is the foundation for deeper (meta)data and information exchange, as well as service orchestration. IODE publishes guidelines on how to share (meta)data as linked open data, serialised in JSONLD using schema.org semantics. This guidance - which specifies the ODIS Architecture (ODIS-Arch) - will extend to other data types and services in the near future. The ODIS Architecture allows all systems with web connectivity to harvest and merge the (meta)data catalogues provided by ODIS Nodes, creating a global map of the ocean datascape. As a core service, IODE harvests all metadata shared by ODIS partners, combines it as a knowledge graph, and processes this to export derivative products (e.g. diagnostic reports and cloud-optimised data products). A web interface for this system has also been developed (https://oceaninfohub.org/).
