Reengenharia do XUL, uma linguagem de descrição da interface do usuário

Abstract

In a modern system information, the interface with the user is a concept key for the success. However, even though in the modero language of modeling "Unified Modeling Language (UML)" the specification of the interface with the user did not have the handling due. The language "XML -based User Interface Language (XUL)" [01 ], recently adopted for the Netscape for the specification of its interface, represents a concrete step in the route of a standard. Although complete and extensible, this language has its scope delimited to the local applications. The fact of XUL be flexible and extensible allows reengineering in its concepts resulting in a more expansive conception of interface with the user. This article considers XUL as a language of abstract interface's description that makes possible diverse rendering over distributed architectures. An abstract description of the interface allows that the final implementation is delayed and customized to the final requirements without additional cost. The proposal expands the semantics of the XUL so the interface's description is build in a model that equally contemplates local and distributed applications. This article still shows to the interactions of XUL with the Python language [ 06,04] and XSL [04] for automatic translation of models in UML for scripts JSP [15][16][18][20], in the case of interface's render in pages HTML.
