11.10 The Rules Editor

The Worklet Rules Editor is a purpose-built tool, deployed as part of the Worklet
Repository, that enables the addition of new rules to existing rule sets of specifica-
tions, and the creation of new rule sets. It has been developed as a Microsoft .NET
2005 based application; the primary reason for choosing a .NET platform was to
provide a demonstration of the interoperability of the web- and Java-based Worklet
Service with a Windows-based administration tool using HTTP messaging.
The main screen of the editor allows users to graphically view the various parts
of each rule node of each rule tree defined for a particular specification. From this
screen users can also add new rules to the current rule set, create new tree sets
for an existing rule set, and create entirely new rule sets for new specifications.
Figure 11.17 shows the main screen with a rule set loaded.
The main features of the screen are explained below.
