Rule Editor
An ontology without rules describes only simple relationships between concepts. More complex relationships have to be described by rules and constraints. This plugin aims to help user in defining and editing rules for ontologies.
Functional Description

The Graphical Rule Editor (GRE) enables the user to formulate rules in a graphical way. Double-Click on a rule. The chosen rule will be displayed with name, namespace and the rule diagram.
Stylized English The Stylized English View shows a natural-language-like representation of the rule diagram currently shown in the Graphical Rule Editor.
Textual Queries Textual Queries allows manually writing F-Logic queries against the modeled ontologies. Before using the editor you have to chose a project. If you specify a module you don�t have to specify the module in the query text, anymore. If you specify a default namespace you can replace <namspace>#<local> with #<local>.
