KNX Information Model
Provides data for the KNX Information Model.

| v2 | TURTLE | JSON-LD | Link | 3-10-3 KNX IoT Information Model |
To visualize the KIM ontology several tools can be used e.g., Protegé (Stanford University), an online viewer can be found here. To import the KIM ontology directly in a tool the following options are available.
- The below URL can be used.
-
- https://update.knx.org/data/Semantics/ontology/v2/ontology.ttl returns a specific (TURTLE) KIM ontology version v2 (the URL is also used by the MaC ETS).
- The ontology IRIs can be used as a URL.
-
- http://schema.knx.org/2020/ontology returns the most recent KIM ontology version, with default TURTLE format
- http://schema.knx.org/2020/ontology?destination_format=ttl returns the most recent KIM ontology version, TURTLE format
- http://schema.knx.org/2020/ontology?destination_format=jsonld returns the most recent KIM ontology version, JSON-LD format
-
http://schema.knx.org/2020/ontology/v2 returns a specific KIM ontology version v2, with default TURTLE format
Downloads with a IRI scheme http:// are usually blocked by web browsers (aka HTTPS-Only Mode setting). If not blocked the links from above are redirected to HTTPS, moreover a direct download with the https:// scheme is also possible, such as from https://schema.knx.org/2020/ontology.
