The informationization 3.0 represented by deep mining and fusion applications of big data is starting, and the software in the traditional static environment is evolving into complex software in the human-cyber-physical ternary environment which is open and dynamic. How to realize the trusted, manageable, and controllable data interconnection on the untrusted and uncontrollable Internet is an urgent problem to be solved. The Internet of Data technical system represented by digital object architecture and identifier resolution technology provides a feasible solution for these challenges. In order to solve the problems such as low transmission efficiency, high coordination cost, and security management issues in the process of data sharing on the Internet, this study proposes identifier resolution standard specifications for human-cyber-physical ternary environments. Moreover, to meet the demands that data resources owned by different entities need to be discoverable, accessible, understandable, trustworthy, and interoperable in the human-cyber-physical ternary environment, this study designs the identifier resolution protocol and implements the identifier/resolution prototype system for human-cyber-physical ternary environments. At last, this study tests the performance of the prototype system, and the validity of the system is verified by applying it to application scenarios.
