Integrating heterogeneous systems using meta information networks

This paper discusses issues related to the integration of distributed heterogeneous environmental information systems. Starting with a brief discussion of the integration problems, a general concept for integrating heterogeneous systems within a meta-information- based network is described. Meta data requirements for this type of integration are developed and a number of application examples are shown, growing in scope towards generic architectures. Future directions of meta information systems are also discussed. In summary, the paper gives an overview of eight years’ work of the author, together with colleagues from various institutions, from early integration concepts to matured system integration tools
