If the MergeImports parameter is set to "on" in the OntoConfig.prp, imported ontologies are directly merged into the importing root ontology. This means that the imported ontologies are not available as separate ontologies as in OntoStudio.
To activate the MergeImports switch, in the OntoConfig.prp set
MergeImports = on
Assume that you have three ontologies A,B, and C. A imports B and B imports C. Then, after loading you have only one ontology A' (consisting of rules and facts from A,B, and C).
NOTE 1: The flag influences only the loading process on OntoBroker start (or reload command).
NOTE 2: The MergeImports flag cannot be used together with project files.
