Rule based systems are often used because people find defining required functionality in terms of rules intuitive. Using them, non-programmers can specify and explain complicated structures and relationships.

Given this, it's really important that non-programmers can create rule sets without understanding syntax or a computer language, and that is why we have created our interactive guided editor.

Our guided editor takes you through the process of creating rules interactively. At each stage of editing it shows you only the alternatives that are valid, thus ensuring you can't create syntactically incorrect rules. You edit and develop rules by selecting from alternatives.

You can experiment with our editor below. This is our newest version based on Microsoft's Silverlight www.silverlight.net. You will need the Silverlight 2.0 runtime to use it. The Metarule editor is Beta software, so we cannot rule out bugs. The editor is set to demo mode, which means that while you can edit rule sets you can't save them.

Select a pre existing rule set from the list at the top, select a rule from the tree in the editor, and try out the editing process in the pane below. 

To begin an edit you must select Rule Sets-> Edit from the menu.
You can add a new rule by selecting Rules->Add Rule from the menu.
