XDL——基于XML的软件体系结构描述元语言

XDL——XML-based meta language of software architecture description language

软件体系结构是指导基于体系结构的软件开发过程的系统蓝图,而软件体系结构是由软件体系结构描述语言(ADL)来描述的.提出1种基于XML的软件体系结构描述元语言XDL作为ADL的元语言.通过XDL构造出的ADL具备大多数基于XML的ADL描述高层软件体系结构的能力,支持系统的扩展与演化,支持系统的验证,保证与其他ADL的互操作性,在软件生命周期中保证体系结构模型的可追溯性.

As the blueprint,software architecture described by Architecture Description Language(ADL) directs software development based on software architecture.An XML-based meta language of ADL,named XDL,is presented.First,ADLs defined by XDL have the ability of describing the high level architecture of software as other ADLs.Second,they support the extension,evolution and verification of software system.Third,they validate the ability to inter operate with other ADLs and the traceability of software architecture model during the software life-cycle.
