Increasingly, application developers are looking for ways to provide
users with higher levels of personalization that capture different elements of a
user's operating context, such as her location, the task that she is currently engaged
in, who her colleagues are, etc. While there are many sources of contextual
information, they tend to vary from one user to another and also over time.
Different users may rely on different location tracking functionality provided
by different cell phone operators; they may use different calendar systems, etc.
In this paper, we describe work on a Semantic e-Wallet aimed at supporting
automated discovery and access of personal resources, each represented as a
Semantic Web Service. A key objective is to provide a Semantic Web environment
for open access to a user's contextual resources, thereby reducing the costs
associated with the development and maintenance of context-aware applications.
A second objective is, through Semantic Web technologies, to empower
users to selectively control who has access to their contextual information and
under which conditions. This work has been carried out in the context of my-
Campus, a context-aware environment aimed at enhancing everyday campus
life. Empirical results obtained on Carnegie Mellon's campus are encouraging.
