Ontology Models to realize federated query

• This repository hosts ontologies based on the CX - 0067 Ontology Models to realize federated query in Catena-X v.1.1.0 standard to realize Knowledge Agent applications.
• The Catena-X Ontology and its initial Catena-X Taxonomy are not intended to be a world model. Instead, it is intended to be an integrative framework with a focus on automotive manufacturing. Therefore, our focus is on defining practical domain ontologies. All definitions in a domain ontology should belong to the same namespace (which is the technical key of the domain) and should use a common prefix. Domain ontologies can refer to classes of other domains by importing concrete versions.
• The Catena-X taxonomy contains all concepts used in domain ontologies. Furthermore, the defined concepts are not only used in the knowledge agent approach, but are also made available to all Catena-X applications.

Ontology Development

• The ontologies are developed using the protégé editor. Therefore, we recommend to use this editor.
• After the development of a new ontology is finished, the documentation is automatically generated as a Markdown file and stored in the repository. In addition, the ontologies are published at w3id.org Catena-X. This also allows access to all versions.

Provisioning of Ontology and Taxanomy

• The ontologies/taxonomies are provided as individual domain files and are simultaneously available as a merged Catena-X ontology/taxonomy in the root directory.
