Preface

The International Conference on Web Information Systems Engineering (WISE)provides an annual forum for exploring research, development, novel applicationsand industrial innovations in the area of Web Information Systems. The 9thedition of this conference (WISE 2008) was held in Auckland, New Zealand fromSeptember 1 to 3, 2008. This volume contains the papers that were presentedduring the WISE 2008 workshops. We commend these papers to you and hopeyou find them useful.

A major objective of the WISE conferences is to identify new issues anddirections in Web engineering, to share experiences, to host discussions, and toinitiate future work and collaborations. Associated workshops devoted to emerg-ing or specialist topics are an important part of the WISE conferences helpingto make them an inspiring experience for all participants. Three workshops wereorganized and held in conjunction with the WISE 2008 main conference:

– The First International Workshop on Web Information Systems Engineer-ing for Electronic Businesses and Governments (E-BAG 2008), chaired bySebastian Link (Victoria University of Wellington, New Zealand), Hui Ma(Victoria University of Wellington, New Zealand), and Jian Yang (MacquarieUniversity, Sydney, Australia);

– The Second International Workshop on Web Usability and Accessibility(IWWUA 2008), chaired by Silvia Abrahao (Valencia University of Technol-ogy, Spain), Cristina Cachero (University of Alicante, Spain), and MaristellaMatera (Politecnico di Milano, Italy); and

– The First International Workshop on Mashups, Enterprise Mashups andLightweight Composition on the Web (MEM&LCW 2008), chaired by MarekKowalkiewicz (SAP Research Brisbane, Australia), Dominik Flejter (PoznanUniversity of Economics, Poland), and Tomasz Kaczmarek (Poznan Univer-sity of Economics, Poland).

Following calls for papers, we received 40 submissions. All submitted paperswere carefully reviewed by at least three international experts, and the best 16were then selected for presentation during the workshops and for inclusion in thisvolume. We would like to thank all authors of submissions, and the membersof the program committees of the WISE workshops for their timely expertise.We are grateful to the workshop organizers for the time and effort they spentto guarantee the high quality of the program, thus contributing to the successof WISE 2008. We further thank Athman Bouguettaya (CSIRO, Australia) andGiorgio Brajnik (University of Udine, Italy), who kindly agreed to give keynotetalks to the workshop participants.

High-quality tutorials are a long-standing tradition of the WISE conferences.They complement the depth-oriented regular paper sessions and keynote talks

VI Preface

by providing conference participants with broad overviews of emerging fields orclear syntheses of results in existing fields. For WISE 2008, we invited Hans-Ludwig Hausen (Fraunhofer National Research Center, Germany), and ShaziaSadiq and Ke Deng (The University of Queensland, Australia) to present tuto-rials on specific areas of their expertise in Web technologies and methodologies.We wish to express our appreciation to the tutorial speakers for their illuminat-ing presentations and their patience in answering questions from the interestedaudience.

Special thanks are due to Yanchun Zhang (Victoria University of Melbourne,Australia) for moderating the WISE 2008 panel discussion on “Engineering Is-sues for the Web 2.0”.

We would like to thank all those who helped to make WISE 2008 a remarkableevent. We are particularly grateful to the local organizers at Auckland Universityof Technology for the wonderful days in New Zealand.
