This volume contains the papers that were accepted for presentation at the - ternationalConferenceonT X, XML, andDigitalTypography, jointlyheld with E the 25th Annual Meeting of the T X Users Group in Xanthi, Greece in the sum- E mer of2004.Theterm DigitalTypography refersto thepreparationofprinted matter using only electronic computers and electronic printing devices, such as laser-jetprinters.Thedocumentpreparationprocessinvolvesmainlytheuseofa digital typesetting system as well as data representation technologies. TXand E its o?spring are beyond doubt the most successful current digital typesetters, while XML is the standard for text-based data representation for both business and scienti?c activities. Allpapersappearinginthisvolumewerefullyrefereedbythemembersofthe program committee. The papers were carefully selected to re?ect the research work that is being done in the ?eld of digital typography using T X and/or its E o?spring. The problems for which comprehensivesolutions have been proposed include proper multilingual document preparation and XML document processing and generation. The proposed solutions deal not simply with typesetting issues, but also related issues in document preparation, such as the manipulation of c- plex bibliographic databases, and automatic conversion of text expressed in one grammaticalsystem to a more recent one (as for the Greek language, converting between monotonic Greek and polytonic Greek). The conference is being graciously hosted by the Democritus University of Thrace in Xanthi and by the Greek T X Friends. We wish to thank Basil K."

This book constitutes the thoroughly refereed post-proceedings of the 4th International Workshop on Distributed Communities on the Web, DCW 2002, held in Sydney, Australia in April 2002.The 25 revised full papers presented together with an introductory overview and outline of the field were carefully reviewed and selected from 59 submissions. The papers are organized in topical sections on adaptive networks, collaborative systems, languages for the Web, and adaptive distributed systems.

Communities are groupings of distributed objects that are capable of com- nicating, directly or indirectly, through the medium of a shared context. To support communities on a wide scale will require developments at all levels of computing, from low-level communication protocols supporting transparent - cess to mobile objects, through to distributed operating systems, through to high-level programming models allowing complex interaction between objects. This workshop brought together researchers interested in the technical issues of supporting communities. This workshop was the third in the DCW series. The ?rst two, entitled D- tributed Computing on the Web, took place in 1998 and 1999 at the University of Rostock, with proceedings published by the University of Rostock Press. This year, the workshop also incorporated the ISLIP (International Symposium on Languages for Intensional Programming) symposium. The ISLIP symposia have taken place every year since 1988, and have led to two volumes published by World-Scienti?c (Intensional Programming I, 1995, and Intensional Progr- ming II, 2000). While the two conferences emerged from di?erent needs, their focus merged to such an extent that it became clear that a joint conference promised to o?er great opportunities.
