This page hosts the downloads for the following KNX IoT frameworks.
- KNX Information Model (KIM)
- KNX IoT 3rd Party API
- KNX IoT Point API
- KNX IoT Router
The page is part of the KNX support system, you can navigate directly to it, or you may be forwarded from https://schema.knx.org.
KNX Information Model
Provides data for the KNX Information Model.
Downloads/Links
| Version | Ontology Files | GitLab | Specification* |
| v2 | TURTLE | JSON-LD | Link | 3-10-3 KNX IoT Information Model (2.1.0) |
| v3 | TURTLE | JSON-LD | Link | 3-10-3 KNX IoT Information Model (work in progress) |
To visualize the KIM ontology several tools can be used e.g., Protégé (Stanford University), an online viewer can be found here. To import the KIM ontology directly in a tool the following options are available.
SPECIFIC VERSIONS
- https://update.knx.org/data/Semantics/ontology/v2/ontology.ttl returns a specific KIM ontology version v2 with TURTLE format (note, this URL is also used by the MaC ETS).
- http://schema.knx.org/2020/ontology/v2 returns a specific KIM ontology version v2, with default TURTLE format
MOST RECENT VERSION
- 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
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.
KNX IoT 3rd Party API
Provides data for the KNX IoT 3rd Party API, based on OpenAPI Specification (OAS).

KNX IoT Point API
Provides data for the KNX IoT Point API,based on OpenAPI Specification (OAS).
