On the API level the only supported syntax is ObjectLogic. This means that the KAON2Factory methods:
| • | axiom |
| • | axioms |
| • | groundTerm |
with the parameter OntologyLanguage are deprecated and only support the OntologyLanguage.OBJECTLOGIC.
Furthermore:
| • | Ontology.addAxioms |
also supports ObjectLogic as syntax only for RDF ontologies in particular. One may use the SPARQL update command to add triples using SPARQL syntax.
