基于OpenDLib的可扩展性数字图书馆功能模型研究

Study on Function Model of Extensible Digital Library Based on OpenDLib

以OpenDLib原型系统为例,深入剖析其设计理念、建设特点、系统信息管理模块、系统信息服务模块、可扩展性,在此基础上概括指出,OpenDLib不仅包含基础的实体图书馆体系结构,而且拥有一套核心的数字图书馆服务。用户完全可以通过定制来满足自身的使用需求。由于该系统设计的基础图书馆体系结构能够提供必要的软件支持,从而保证兼容新的文档模型——DoMDL的各类核心服务之间的关联与合作,并使之可以被动态扩展与切割。论文最后指出具有可扩展性功能的数字图书馆在功能模型上的基本组成要素。

Based on the prototype OpenDLib,the paper analyses the design idea,construction characteristics,system information management module,system information service module and ex- tensibility of OpenDLib,then concludes that OpenDLib not only includes the architecture of tradition- al library,but also embeds a suit of core services of digital library that makes users satisfy them- selves through customization.With the help of the softwares provided by the architecture of tradition- al library,the relation and cooperation among core services are compatible with DoMDL,and the core services can be extended and breakuped dynamically.In addition,the functions model of ex- tensible digital library is discussed also.
