数据共享平台的数据访问及其在Android终端的呈现

摘要

Realizing data sharing can make more people take full advantage of the existing data resources to create new value. CKAN (Comprehensive Knowledge Archive Network) is the world's leading open source data platform. It can manage the existing data resources and make them sharing. So this paper implements a CKAN APP based on Android development in order that the users can view the sharing data resources of CKAN anytime and anywhere. This paper mainly uses the Android client development technology to realize the access into data resources of CKAN by CKAN API, then changes the format of the obtained data resources into an appropriate format and stores them, eventually, displays the data resources at the Android terminal. The test results show that CKAN APP developed in this paper provides an available APP tool for users to view the sharing data resources of CKAN anytime and anywhere.%实现数据共享,可以使更多的人更充分地利用已有数据资源,创造新的价值.CKAN(Comprehensive Knowledge Archive Network)是世界领先的开源数据平台,对收集的数据实现管理和共享.本文实现了一款基于Android开发的CKAN APP,以便用户可以随时随地查看CKAN平台上的共享数据.本文主要是运用Android客户端的开发技术,通过CKAN的API来访问CKAN平台的数据资源,然后将访问到的数据资源转化为合适的格式存储起来,最终将数据在Android终端呈现出来.测试结果表明:本文开发的CKAN APP,为用户随时随地查看CKAN平台的共享数据提供了一个可用的APP工具.
