Functional Description
The F-Logic Editor shows the content of the ontology as F-Logic in a textual editor.
User Documentation
In order to open the F-Logic editor, select either Edit F-Logic source or Edit F-Logic source (without instances) from the context menu of an ontology. You get a higher performance when chosing "without instances". In the event of e.g. a renaming the ontology might become inconsistent, because the instances will be untouched.
The editor provides a syntax highlighting, warnings for syntax errors just to name a few. The Outline displays the entities contained in the current edited ontology.
