A Model-Based Approach for Supporting Offline Interaction with Web Sites Resilient to Interruptions | | Detalle: |
|
Despite the wide
availability of Internet connections, situations of interrupted work caused by
accidental loss of connectivity or by intentional offline work are very frequent.
Concerned by the negative effects of interruptions in users’ activities, this
work investigates a new approach for the design and development of Web
applications resilient to interruptions. In order to help users to recover from
interruptions whilst navigating Web sites, this paper proposes a model-based
approach that combines explicit representation of end-user navigation, local
information storage (i.e. Web browser caching mechanism) and polices for
client-side adaptation of Web sites. With this model, we are able to provide
users with information about which Web site’s contents are available in an offline
mode and how they can get easy access to local cache content. Moreover, the
model can be also be used to set proactive mechanism such as pre-caching Web
pages that are likely to be seen by users. Mechanisms for synchronizing Web contents when the interruption is
resumed are also discussed. Such model-based approach is aimed to be used to
build new Web sites from scratch but it can also be used as a mapping support
to describe offline navigation of existing Web site. This paper presents the
conceptual model, a modeling case study and a tool support that illustrates the
feasibility of the approach. | |
