SEASPRITE facilitates the electronic exchange of data in the shipping industry by utilising a common intermediary language, STEP, and thus avoiding the need for translators between each piece of proprietary software. SEASPRITE also includes a CORBA-based tool, the DEM, for the management of the exchanged data.
At present, most data exchanges within the shipping industry are carried out by moving paper by post or courier. The electronic transfer of data offers many advantages over present practice, chiefly ones of time and accuracy. For example, it takes about a day to transfer data by paper (c.f. minutes for electronic transfers) and inputting data from this paper to computers takes many man-days (c.f. hours for translation from computing system to computing system). To implement the electronic transfer of data, SEASPRITE uses a common language, STEP, for ship product data. For any system to be able to exchange data with any other system using this intermediary language, two translators are required, a STEP output translator and a STEP input translator. For example, if five partners were collaborating in a ship building project, each using a different system, then ten translators would be required for data exchange between any pair of partners in either direction in the case where STEP was used, but twenty (each of the five systems would have to be able to export to each of the other four) would be required in the case where no intermediary language was used. In addition, SEASPRITE provides a software architecture, the Data Exchange and Management architecture (DEM), for the transparent management, access and exchange of information and services across company boundaries.
The DEM is developed using CORBA, and provides authorised access to information within inter-company projects, through the co-operation of CORBA servers located within various companies.
The SEASPRITE project has also developed a Java Information Browser application and applet, providing a Web-enabled graphical user interface for viewing, managing and obtaining the information within the DEM.
