The Panama Ship Registry: 1917–2017

The Panama Ship Registry has its origins in the year 1917. Nowadays, Panama has the largest vessel registry in the world. The second placed registry in the world ranking is Liberia, which does not have even half the number of Panamanian ships. In this Centennial, the aim of this paper is to analyse the evolution of the Panamanian Registry, the structure of the Panamanian-flagged fleet and the level of compliance with international standards in relation to maritime safety and working conditions. To undertake the analysis, two different qualitative and quantitative approaches are compared and integrated for the evaluation of the Panama Ship Registry: the degree of ratification and enforcement of the Conventions and Recommendations of the International Maritime Organization and International Labour Organization, and the results of Panamanian flagged vessels in inspections carried out within the major Port State Control Memoranda of Understanding. This paper fills a research gap by discussing an approach to the concept of flag of convenience and flag State, Panama is more an international registry, whose role is becoming less important from the points of view of safety or working conditions. The fleet performance evolution has been very positive as evidenced by the data presented in this article regarding Port State Control.     

VO-DAS Registry系统的设计与实现

为了给天文学家提供一个统一访问分布存储于世界各地数据中心的异构天文数据资源的方案,中国虚拟天文台项目组设计了虚拟天文台数据访问服务(VO-DAS)。VO-DAS支持国际虚拟天文台联盟(IVOA)制订的各项相关标准,使得它具有良好的互操作性。VO-DAS Registry系统是VO-DAS系统的重要组成部分,它为VO-DAS系统获取数据资源的元数据,从而使得VO-DAS更好的管理和应用这些数据资源。在这个过程中,此系统符合IVOA的相关标准。
