Interoperability between different port information systems

Abstract

—This paper discusses one of the most common level of data exchange between the different port systems issues in order to exploit the internal resources and the collective resources of all the different systems. Our goal is to overcome any type of heterogeneity conflict: semantic, technical and structural during the exchange of information between each different heterogeneous system. In this paper we propose a practical architecture to facilitate the exchange and communication between all the different port systems without modifying the local information systems. Our architecture is based on three levels: 1) User level 2) Mediation level, 3) Source level. The first level is dedicated to applications and users, the second includes various tools to process queries and solve conflicts (technical, structural, semantic) through mediators and ontologies. The third level concerns local information systems and adapters that provide unified interface information systems. The use of XACML format will establish a secure data exchange and standardization of a good decision for the access control of different types of documents belonging to various port information systems
