(1) Most importantly, YAMATO is designed with both engineering and philosophical minds. (2) YAMATO is based on a sophisticated theory of roles, given that the world is full of roles. (3) YAMATO has a tenable theory of functions which helps to deal with artifacts effectively. (4) Information is a `content-bearing' entity and it differs significantly from the entities that philosophers have traditionally discussed. Taking into account the modern society in which a flood of information occurs, YAMATO has a sophisticated theory of informational objects (representations). (5) Quality and quantity are carefully organized for the sake of greater interoperability of real-world data. (6) The philosophical contribution of YAMATO includes a theory of objects, processes, and events. Those features are illustrated with several case studies. These features lead to the intensive application of YAMATO in some domains such as biomedicine and learning engineering. 收起
