Circular Economy Ontology Network (CEON)
The Circular Economy Ontology Network (CEON) provides a shared vocabulary for representing information about circular economies in the form of a network of ontology modules.
The figure below shows an overview of the topics covered. The lines between the boxes represent some common-sense relations between the topics, which are represented as formal relations within the actual modules, such as owl:import
or specific object properties connecting concepts inside the modules. The light blue box (location) is not part of CEON, but instead reuses a standard geographical ontology such as the OGC GeoSPARQL standards.

Core Modules
The set of core modules that are in this release of CEON forms a set of generic reusable ontology building blocks and include Actor, Process, Resource, and Circular Value Network.
