本文介绍了一个建立在GPV/JMA档案之上的Web服务系统。该档案馆将提供日本气象厅(JMA)提供的每日业务天气预报数据。目前，它正在服务于几种类型的GPV数据，如全球光谱模式数据、区域光谱模式数据和中尺度非静力模式数据。为了使这些数据更易从网络上使用，我们构建了一个Web服务系统，由几个Web服务组成，如元数据生成、搜索和渲染，以及一个允许用户执行基于BPEL的科学工作流的工作流引擎。特别是，我们为GPV数据设计了专用的元数据格式，并实现了元数据提取程序，以实现对传入GPV数据的自动元数据提取。本文对整个系统进行了描述，并对构建的服务进行了详细的描述。
In this paper we report a Web service system constructed on top of the GPV/JMA Archive. The archive is to offer the daily operational weather forecasting data provided by the Japan meteorological agency (JMA). Currently, it is serving several kinds of GPV data, such as global spectral model data, regional spectral model data, and meso- scale non-hydrostatic model data. In order to make those data more usable from the Net, we have constructed a Web service system, consisting of several Web services, such as metadata generation, searching, and rendering, and a workflow engine that allows users to execute BPEL based scientific workflows. In particular, we have designed a dedicated metadata format for GPV data, and implemented metadata extractor to enable automatic metadata extraction for incoming GPV data. In this paper, the entire system and the details of the constructed services are described.
