A Study on Marine Information Sharing and Integration Model Based on Ontology

By analyzing the difficulty in information integration and sharing of ocean, a hierarchical model, including distributed resource layer, data integration layer, services layer, service integration layer and application layer, was proposed to integrate information. Exchange data format based on ontology was defined to transform data between different modules. In addition, service integrator was introduced to the layer model to achieve service collaboration. Finally, an ocean disaster query system was developed to testify the validity and feasibility of the model.
