Version IRI: https://openric.org/ns/ext/v1.6.0 · Released: 2026-10-20 · Specification: v0.55.0

The current release. Its Turtle is /ns/ext/v1.ttl; the copy fixed at this release is in the specification repository at the v0.55.0 tag. It adds physical storage, which RiC-O 1.1 does not model: openricx:Container and openricx:ContainerType, openricx:isOrWasStoredIn with its inverse openricx:storesOrStored, and openricx:hasContainerType with its inverse. A container is placed in a rico:Place with RiC-O’s own rico:hasOrHadLocation. No term is changed or removed; 1.5.0 is the release before it.

The terms themselves do not change IRI between versions: every term is https://openric.org/ns/ext/v1#<name>. The ontology page lists them, with the version history.
