Ontology Diff Tool

Description

Tool to compare two ontologies and to create a diff of both ontologies. The tool creates various types of diff files:

  • ADDED_AXIOMS ... all axioms which are present in ontology B, but not in ontology A
  • COMMON_AXIOMS ... all axioms which are present in both ontologies
  • COMPLETE_DIFF ... all axioms which are present in (ontology A but not in B) & (ontology B but not in A)
  • DELETED_AXIOMS ... all axioms which are present in ontology A, but not in ontology B

Example & Usage

The OntologyDiff Tool offers a command line interface support following parameters:

    
usage: Ontology Comparator
 -f,--format <format>     ontology format. 'OWLXMLOntologyFormat'
                          (default),'ManchesterOWLSyntax'
 -i1,--ontologyA <file>   use given file as ontology A
 -i2,--ontologyB <file>   use given file as ontology B
 -out,--output <file>     use given output file
 -v,--verbose             turn on verbose mode

An exmaple usage can be ...

 
java -jar ontologydiff-1.0.1.jar -i1 /path/to/file/in1.owl -i2 /path/to/file/in2.owl -out /path/to/file/out.owl -v

The output of the program will look similar to this ...
