Abstract

This paper presents a new framework for Digital Ocean construction that includes a supporting layer, basic layer, data layer, service layer, application layer, and assurance layer; the functional composition and architecture of each layer are described. The model framework realizes effective integration, exchange, and sharing of marine information, basic geographical information, and closely related economic and social information through open architecture and a standardized service mode. The research results revealed that the proposed framework overcomes the defects inherent in the existing Digital Ocean systems. Therefore, it serves as a basic framework for policymakers, provides unified technical architecture for constructing a Digital Ocean system for use by managers, provides a unified platform for industry users to integrate marine information, and provides an interface for use in developing application systems. The proposed basic framework model for Digital Ocean construction has already been adopted for implementation by the Qingdao Municipal Government in China and has now been extended to Shandong Province. The framework model will be further extended over a broader range.
