 | ASSIGNED                   | Represent the allocation by a RIR of a network resource (AS, Prefix) to a resource holder (see OpaqueID). Or represent the assigned IP address of an AtlasProbe.                                                 |
 | AVAILABLE                  | Relate ASes and Prefixes to RIRs (in the form of an OpaqueID) meaning that the resource is not allocated and available at the related RIR.                                                                       |
 | CATEGORIZED                | Relate a network resource (AS, Prefix, URL) to a Tag, meaning that the resource has been classified accordingly to the Tag. The **reference_name** property provide the name of the original dataset/classifier. |
+| CENSORED                   | Relate ASes to an OONI censorship test in form of a Tag or a network resource (IP, URL), meaning that there exists a censorship test result from a probe in this AS to the connected node. The **reference_name** property provides the name of the test.|
 | COUNTRY                    | Relate any node to its corresponding country. This relation may have different meaning depending on the original dataset (e.g. geo-location or registration).                                                    |
