Key facts

• Access to a growing number of industrial semantic definitions, resolved under the URL semantic-hub.io/semanticId
• Free of charge to use under the open license DL-DE Zero 2.0 ("Datenlizenz Deutschland")
• Maintained by a growing community that likes the vision of a central hub like we: https://semantic-hub-community.coapp.io/
• Trusted partner for standardisation organizations that want to publish their definitions on a central hub
• already xxx definitions ingested

Purpose

The hub was initiated as Wikibase to solve the problem of scattered dictionaries and APIs that make it hard to find the information behind semantic definitions instantly. Semantic definitions are the meta data (e.g., unit of measure) for concepts (e.g., temperature) that form the vocabular that is strongly needed for:

• an efficient data mapping, consistency checking and interface design
• interoperability of technical systems and the Asset Administration Shell
• common vocabulary and language in data spaces, like Factory-X, Catena-X or Dataspace4Everybody

Simple and clear rules

Identifier semanticID

change to issuer item instead of issuerID pageI

dentifier (the semanticID) of semantic definitions have to be unique, e.g., URI/IRI, IRDI or URN. In this wikibase there are two kinds of items that have to have a semanticID, the Definition item with a non-versionized semanticID and the Version item with a versionized semanticID.

When creating a semantic definition initially in the semantic hub and there is no semanticID availabe we recommend to create your semanticID as following:

1) Add an issuerID to the issuerID page in order to reserve your namespace

2) Name your semanticID according this structure:

• Definition item: https://semanticid.io/{IssuerID}/{LocalIdentifier} or https://semanticid.io/{IssuerID}/{LocalGroupIdentifier}/{LocalIdentifier}
• Version item: https://semanticid.io/{IssuerID}/{LocalIdentifier}/{Version} or https://semanticid.io/{IssuerID}/{LocalGroupIdentifier}/{LocalIdentifier}/{Version}

Example: https://semanticid.io/example/temperature (non-versionized) or https://semanticid.io/example/temperature/0 (versionized)

Recognition of namespaces

change to issuer item instead of issuerID page

Please inform the community about your namespace (e.g., IRDI or URI) with an entry in the issuerID page. Only owners of namespaces are allowed to publish Version items for 'their' Definition items. That means, that every user can work on these definitions commonly with the owner but to make a definition official in a certain namespace, will be only possibly for namespace owners.

Open license

To reach the communities goal of true interoperability and openess every semantic definition in this wiki has to comply to DL-DE Zero 2.0 ("Datenlizenz Deutschland") or CC0. More information can be found here: https://www.govdata.de/dl-de/zero-2-0 or CC0 - Creative Commons. Owner of data sets can publish their data under these licenses on semantic-hub.io. Users that publish not their own data have to verify that the data is licensed according to DL-DE Zero 2.0 or CC0.
