Multilateral defense cooperation in the Indo-Asia-Pacific region: Tentative steps toward a regional NATO?

Some U.S. military leaders have asserted that the United States, Japan, Australia, and India and the Republic of Korea are developing multilateral defense cooperation to deter aggression and uphold norms much like North Atlantic Treaty Organization (NATO) has in Europe. Frequent military exercises and China’s threats to freedom of navigation (FoN) and North Korea’s nuclear missiles comprise the motive force for such cooperation. However, cooperation thus far has been trilateral and minimal, given divergent national interests and dispersed geopolitical locations. Cooperation among Japan, Republic of Korea (ROK), and the United States is increasing given the threat, but ROK’s public opinion is divided about Japan. Australia, Japan, and India have increased cooperation with the United States but are reluctant to conduct FoN operations with the United States to challenge China’s expansionism in the South China Sea. If China becomes more aggressive and blocks FoN or seizes territory, development toward an Asian NATO is possible.     

基于元数据的信息共享机制研究

数字信息的逐渐增长以及信息技术在各领域内的广泛应用,使得信息共享成为信息建设的重要组成部分。面对建设过程中存在的大量格式不兼容的数据及数据标准的专有化,文中针对在元数据基础上的信息共享机制进行了研究,通过分析美军网络中心数据策略和美国防部发现元数据标准(DDMS)的内容,提出一个基于元数据的信息共享系统的总体构建方案。
