ABSTRACT
Mobile computing and localization systems recent diffusion enables the use of contexts and trails in several applications, with the incorporation of resources for content adaptation and distribution. A trail represents a set of user contexts, historically organized. This article presents a proposal for managing multiple trails in mobile computing environments. Its differential is the representation of the data of each entity in several trails. This approach allows the multiple aspects of interest for the entity to be modeled and stored. In addition, facilitates its use in different applications, which may need only part of the elements in this set of trails. In this way, this proposal extends the possibility of context composition for entities, providing greater flexibility to their use. This is demonstrated in two case studies of the application of this model.
