Ubiquitous computing has been identified as one of the next major directions in computing. This paper identifies several requirements to support data access in ubiquitous computing environments and presents a design to meet the requirements. The impetus for the design lies in three areas; 1)~content adaptation, 2)~data grouping, and 3)~location awareness. The system is composed of data access building blocks, which allows devices to customize the way in which they retrieve data. All data in the system is indexed and typed, which facilitates data grouping, automatic content conversions, random access, and higher level services, such as streaming. The personal storage of a user is implicitly linked to a user and can be automatically incorporated into an environment conditioned on their physical presence.
