document: eBag : a ubiquitous Web infrastructure for nomadic learning This paper describes the eBag infrastructure , which is a generic infrastructure inspired from work with school children who could benefit from a electronic schoolbag for collaborative handling of their digital material . The eBag infrastructure is utilizing the Context-aware HyCon framework and collaborative web services based on WebDAV . A ubiquitous login and logout mechanism has been built based on BlueTooth sensor networks . The eBag infrastructure has been tried out in field tests with school kids . In this paper we discuss experiences and design issues for ubiquitous Web integration in interactive school environments with multiple interactive whiteboards and workstations . This includes proposals for specialized and adaptive XLink structures for organizing school materials as well as issues in login\/logout based on proximity of different display surfaces .
