Korean government, port and logistics companies have made a lot of effects t exchange electronic documents between themselves and their partners. As a result of it, Korean Electronic Data Interchange(EDI) standards were make by the Korean Electronic Data Interchange for Administration, Commerce and Transport(EDIFACT) committee and the standards have been used by companies and governmental organizations in Korea. However, Korea port and logistics EDI system is based on Value Added Network (VAN) and a VAN company has monopolist right to relay EDI documents to Ministry of Maritime Affairs & Fisheries(MOMAF) and Customs Service. Therefore it leads to a lot of problems such as inconvenient software, expensive transmission fee, insufficient improvement of business process and the difficulty of connection with the in-house systems of user companies, To solve these problems, United National Centre for Trade Facilitation and Electronic Business(UN/CEFACT) and Organization for Structured Information Standards(OASIS) are aimed to progress for eXtensible Markup Language(XML) and Internet-based Electronic Business Extensible Markup Language(ebXML) electronic commerce framework. This research is trying to derive an conceptual ebXML model based e-Business for port and logistics industry. Especially, for improving extant problems in the port and logistics industry, this research proposes the Information Strategic Planning(ISP) and Proof of Concept(POC) for ebXML system.
