基于REST模式的环境保护档案信息资源服务

Services of Environmental Protection Archival Information Resources Based on REST Mode

为解决各级环保部门档案管理存在的数据类型复杂、资源利用率低等问题,实现异构环境下环保档案信息资源的整合、共享,提出一种基于表述性状态转移架构模式的环境保护档案信息资源Web服务方案。首先,探讨基于REST架构设计环境保护档案信息资源服务的关键环节;其次,详细阐述档案信息服务的REST资源识别、档案实体及元数据等资源的标识及表述、档案信息资源相关操作等方面的具体设计方法;最后,基于J2EE及Spring 3.0 REST框架,给出环境保护档案信息资源服务的具体实现,并将其应用于"分布式环保档案信息资源共享平台"中,取得较好效果。

The paper proposes a scheme of environmental protection archival information resources （EPAIR） services based on REST architecture to solve some problems （such as complex data types and low utilization of archival resources and so on）, for sharing of environmental protection archival information resource in heterogeneous environment. Firstly, the key points of designing EPAIR services are discussed. The specific steps of the EPAIR services are elaborated in detail including identification of resource, resource identifiers and resource representation of environmental protection archival and its metadata, and resource CRUD operation. Finally, the essentials on how to implement it under Spring 3.0 REST and J2EE are elaborated. Moreover, the services are applied to environmental protection archival information resources sharing platform and get better results.
