基于Web Service和元数据的农业生物质特性数据共享平台研究

农业生物质特性数据共享平台是实现农业生物质基础性技术参数全社会共享的平台,也是发展优质、高效、低耗生物质产业的公益性基础。其关键在于如何将区域存储分散、数据源不统一的生物质特性数据进行标准化处理,最终实现共享。通过对平台关键技术的分析,提出以野中心数据库要要数据分节点冶为架构,以元数据和Web Service 技术为基础的多层次数据共享平台。对平台的实现流程、Web Service 服务流程和元数据服务流程进行分析,开发了农业生物质特性数据共享平台,平台能实现跨平台和跨操作系统的部署。该软件平台已经投入使用,涉及农作物秸秆、堆肥、畜禽粪便的化学组成特性、物理和热特性、热化学工程特性以及机械特性方面的数据,能方便的为用户提供稳定农业生物质特性数据共享服务。

Research on agricultural biomass characteristics data sharingplatform based on Metadata and Web Service

Agricultural biomass characteristics data sharing platform is used to share the agricultural biomass parameters forthe whole society, and it is also the foundation for the development biomass industry. The key point of the platform is how tostandardize, integrate and share the diverse data whose sources are dispersed. After analysis of the key technologies, the platformcomposed of "Central Database-Data Node" and based on Web Service and Metadata was designed. Then some implementation of thekey technologies is discussed in the paper, such as the service process of Web Service and Metadata. By using these technologies, theAgricultural biomass characteristics data sharing platform was developed, which can be deployed across multi-platform and differentoperating systems. The software platform has been practically used, and the platform have the data of chemical compositecharacteristics, physical and thermal properties, thermochemistry engineering properties and mechanical properties has beenintegrated into the platform.
