“A crucial aspect of most (if not all) Web systems is the way in which information is utilised and managed. Recent work on areas as diverse as topic maps, information architectures, adaptation of the Unified Modeling Language, agile development methods such as extreme programming, and modelling for the semantic Web, have all contributed to an emerging understanding of how to design the information structures that underpin the Web (and of course much of this work has in turn been informed by research in areas like hypertext and HCI).” (David Lowe – Journal of Digital Information 5.2)
