On the use of XML for port communications

In this paper we analyze and compare EDI and XML based communication between shipping lines, terminal operators, government agencies, trucking companies, rail operators and other agents at the example of the Los Angeles and Long Beach ports. We investigate the suitability of (1) XML/EDI, (2) EDIINT (Web EDI), (3) Collaboration EDI and (4) Web Services for use as communication platforms at the ports.Currently at the Los Angeles and Long Beach ports information is mostly shared in a bilateral manner. As a result we describe and recommend an approach where terminals share data with shipping lines/carriers, rail operators, trucking companies, truckers and government agencies using XML based Web Services. This approach allows agents to either make information accessible through a web browser or through direct computer system to computer system communication. In the latter approach the terminals computer system will function as an automated information clearing house that can provide up-to-date, real-time information to all interested and authorized parties. Web Services furthermore allow securing and authenticating this information, protecting its dissemination. We believe that this approach can lead to increased throughput at the ports and an increase in capacity.
