OpenCS

Main OpenCS ontology repository.

The ontology is currently in its early stages of development. It was built from a subset of the Microsoft Academic Knowledge Graph by Michael Färber. You can find the scripts used for making OpenCS from MAKG in this repository.

See also the documentation where you will find more information about the schema and ontology modules.

Contents

• /schema/schema.ttl – OpenCS schema (upper ontology)
• /ontology – OpenCS ontology
  • header.ttl – header with ontology metadata
  • authors.ttl – manual list of ontology authors
  • core – core of the ontology, split into one Turtle file per concept. The files are grouped by 1000 into directories to help with potential filesystem or file browser issues.
  • makg_extra.ttl.gz – extra assertions carried over from MAKG
  • opencs_to_makg.ttl.gz – equivalence relations between OpenCS and MAKG
  • shacl_constraints.ttl – the file with SHACL constraints for ontology validation

Releases

The dev release tag corresponds to the main branch in the repository and is updated automatically.

Tagged (versioned) releases are created manually and follow the Semantic Versioning scheme.

To create a new tagged release (example for version 1.2.3):

$ git checkout main
$ git pull
$ git tag v1.2.3
$ git push origin v1.2.3

The rest (packaging and release creation) will be handled automatically by the CI.
