Abstract: In the construction of marine geological information service system, the big data utilization is a challenge. This paper puts forward four suggestions for consideration: using Internet Web platform and Web development technology, following the Internet protocols and OData data open protocol, building restful APIs based lightweight Web services, and researching web-based interactive data visualization methods. Learning from the Internet success model of specification, technology and application complementary strategies, the APIs core application ecosystem will be expected to gradually promote openness, sharing and interoperability for marine geological information resources.
