This volume contains the ?nal proceedings for the Metainformatics Symposium 2002 (MIS 2002). This event was held during 7-10 August on the campus of Aalborg University Esbjerg, located in Esbjerg, Denmark. MIS is at once both an extension of the previous Structural Computing (SC) Workshop series (see LNCS vols. 1903 and 2266 -available from Springer-Verlag -for the proceedings of SC2 and SC3), and a broadening of the themes of that workshop series in several new and exciting directions. I hope you ?nd the work presented in these proceedings as interesting and exciting as I have. I would like to thank Dr. Siegfried Reich and Mrs. Britta Jensen for their help in compiling these proceedings. Also, this volume would not have been possible without the support of Springer-Verlag, Heidelberg. In particular, I would like to thank the executive editor of the LNCS series, Mr. Alfred Hofmann.
