Scope is a framework built around an extensible implementation of the Hierarchical Model-View-Controller (HMVC) pattern similar to the pattern described in HMVC: The layered pattern for developing strong client tiers . It provides an easy-to-use Java library that can be used as a basis for component-oriented application development following the layered architecture detailed in Sun’s J2EE and in Cheesman/Daniels: UML Components .
Applications developed using Scope are “view-agnostic”: a Swing application uses the same infrastructure and patterns as a web application that happens to use XML/XSLT to generate HTML, or a JSP-based application. The framework has been used in production systems built using the default Swing and XML/XSL Servlet implementations, as well as proprietary VoiceXML, ColdFusion and custom XML/XSLT implementations.
