Study on Ontology Based Military Metadata Model

Metadata is "the data about data",it's the information that is used to describe resources' properties.The purpose of using metadata is to find,get and use resources easily.However,different department has different metadata,which made data can not share among departments.For the sake of solving the problem,introduce the thought of ontology into metadata model,and then present an ontology based military model refer to the military standard.Comparing with the traditional one,this model can express domain concepts and the relationships between them from semantic level,which provides theoretical basis for solving the isomerism between information systems.
