Abstract: An extensive and powerful XML meta-data rule-based language and system for developing a use-interface for configuring, monitoring and provisioning a telecommunications system is provided. The language is based on rules that define configuration objects and relationships. The rules are organized into files that define the individual objects used to configure the telecommunications system. The rules are interpreted at run-time to instruct the system to present appropriate user-interface controls to create, edit, and manipulate the objects. The rules will direct the specific editor for objects' properties, sometimes consisting of edit controls, combo box controls, multiple selection controls, or dialog boxes for IP addresses, point codes, or dates. The rules can enforce dependencies and cardinalities, as well as display customized data tables across different objects.
